Alternating Current (AC)
 -  An electric current which periodically reverses direction. It is the form in which electric power is delivered to businesses and residences.
Direct Current (DC)
 -  Flows in one direction and does not reverse its direction of flow as does alternating current.
Intermetallic
 - 

A term used to describe a compound material composed of two or more metals or of a metal and a nonmetal.

Across the arc wire feeders
 -  Also referred to as voltage-sensing wire feeders. The wire feeder is powered by the welding cable instead of a control cable. This configuration provides the benefit of fewer cables running back to the power source. Voltage control at the point of use is not possible without the addition of a control cable however, technologies such as ArcReach and CrossLinc now provided remote control capability via the welding cable.
Actual throat
 -  The shortest distance from the root of a fillet weld to its face.
All-weld-metal test specimen
 -  A test specimen with the reduced section composed wholly of weld metal

Amperage
 -  The measurement of the amount of electricity flowing past a given point in a conductor per second. Current is another name for amperage.
Arc
 -  The physical gap between the end of the electrode and the base metal. The physical gap causes heat due to resistance of current flow and arc rays.
Arc blow
 -  The deflection of an electric arc from its normal path because of magnetic forces.
Arc force
 -  Arc force prevents the electrode from sticking during welding. Arc force is a temporary increase of the output current during welding when the arc is too short. This feature supports production with consistently excellent arc performance. It also enhances simple position welding making the job easier. In order to produce an outstanding weld performance on a variety of electrodes (rutile, basic or cellulose), the arc force can be finely adjusted with a simple knob. To have a smooth arc with less spatter, set the knob to minimum (rutile, basic). For a more crisp arc, with more penetration, set it to maximum.
Arc seam weld
 -  A seam weld made by an arc welding process.
Arc spot weld
 -  A spot weld made by an arc welding process.
Arc time
 -  The time during which an arc is maintained in making an arc weld.
Arc voltage
 -  The voltage across the welding arc.
Arc Welding
 -  Welding processes which use heat from the resistance of current flow and arc rays to produce coalescence of metals. Can use either direct (DC) or alternating (AC) current, consumable or non-consumable electrodes, with or without the application of pressure.
Arc welding electrode
 -  A component of the welding circuit through which current is conducted between the electrode holder and the arc.
Arc welding gun
 -  In semi-automatic, machine and automatic welding, a manipulating device to transfer current and guide the electrode into the arc. It may include provisions for shielding and arc initiation.
As-welded
 -  The condition of weld metal, welded joints, and weldments after welding but prior to any subsequent thermal, mechanical, or chemical treatments.
Asynchronous welder generator
 -  An asynchronous generator is an alternator that utilizes an air-gap rotating magnetic-field between a stator and a rotor to interact with an induced current in a rotor winding. An asynchronous generator requires no maintenance since there is no collector ring, brush, or rotor excitation winding. It is sometimes called an induction generator. General efficiency is higher than that of a synchronous generator with the same capacity and the same speed. Red-D-Arc's GX200 DC CC gas engine welder employs an asynchronous generator to produce welding current.
Autogenous weld
 -  A fusion weld made without the addition of filler metal.
Automatic welding
 -  Welding with equipment which performs the welding operation without adjustment of the controls by a welding operator. The equipment may of may not perform the loading and unloading of the work. See machine welding.
Automatic Welding
 -  Uses equipment that welds without the constant adjusting of controls by the welder or operator. Equipment controls joint alignment by using an automatic sensing device.
Axis of a weld
 -  A line through the length of a weld, perpendicular to and at the geometric center of its cross section.
Back gouging
 -  The removal of weld metal and base metal from the other side of a partially welded joint to assure complete penetration upon subsequent welding from that side.
Backhand welding
 -  A welding technique in which the welding torch or gun is directed opposite to the progress of welding. Sometimes referred to as the “pull gun technique” in GMAW and FCAW.
Backing
 -  A material (base metal, weld metal, carbon, or granular material) placed at the root of a weld joint for the purpose of supporting molten weld metal.
Backing pass
 -  A pass made to deposit a baking weld.
Backing ring
 -  Backing in the form of a ring, generally used in the welding of piping.
Backing strip
 -  Backing in the form of a strip.
Backstep sequence
 -  A longitudinal sequence in which the weld bead increments are deposited in the direction opposite to the progress of welding the joint. See block sequence, cascade sequence,continuous sequence, joint building sequence, and longitudinal sequence.
Bare electrode
 -  A filler metal electrode consisting of a single metal or alloy that has been produced into a wire, strip, or bar form and that has had no coating or covering applied to it other than that which was incidental to its manufacture or preservation.
Bare metal arc welding (BMAW)
 -  An arc welding process which produces coalescence of metals by heating them with an electric arc between a bare or lightly coated metal electrode and the work. Neither shielding nor pressure is used and filler metal is obtained from the electrode. (This process is now obsolete in industrial applications).
Base metal (material)
 -  The metal (material) to be welded, brazed, soldered, or cut.
Base metal test specimen
 -  A test specimen composed wholly of base-metal.
Bend Test
 -  A destructive testing method where the weld specimen is bent to a specified bend radius to evaluate the ductility and soundness of the weld. See Weld Quality Assurance

Constant speed wire feeders
 -  A constant speed wire feeder is used only with a constant voltage (CV) power source. This arrangement requires an extra control cord between the wire feeder and the power source but that allows operators to control both voltage and wire feed speed (amperage) at the feeder, a big benefit when working remotely. Further, voltage and amperage values remain constant unless manually adjusted, and both can be adjusted independently of each other. When welding procedures specify wire feed speed and voltage (instead of amps and volts), a constant speed feeder may be your best choice. When you set the controls for a wire feed speed of 250 inches per minute, that's what the system delivers. Wire feed speed does not vary like it does with a voltage sensing system. Both VS and RC feeders have digital meters, typically an option, make setting e xact parameters easier. The meters display wire feed speed or volts (one at a time) or they can be set to display amps or wire feed speed (one at a time).

Inadequate joint penetration
 -  Joint penetration which is less than that specified.
Incomplete fusion
 -  Fusion which is less than complete.
Indentation
 -  In a spot, seam, or projection weld, the depression on the exterior surface or surfaces of the base metal.
Induction heating
 -  Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents. See induction heating systems
Inert gas
 -  A gas which does not normally combine chemically with the base metal or filler metal. See also protective atmosphere.
Infrared radiation
 -  Electromagnetic energy with wavelengths from 770 to 12000 nanometers.
Intergranular penetration
 -  The penetration of a filler metal along the grain boundaries of a base metal.
Intermittent weld
 -  A weld in which the continuity is broken by recurring unwelded spaces.
Interpass temperature
 -  In a multiple-pass weld, the temperature (minimum or maximum as specified) of the deposited weld metal before the next pass is started.
Inverter Welding Power Source
 -  Power source that increases the frequency of the incoming primary power, thus providing for a smaller size machine and improved electrical characteristics for welding, such as faster response time and more control. Inverters are more portable and lighter weight than traditional transformer-rectifiers, making them easier to maneuver around the job site. In addition, inverters offer high-quality, multi-process welding capabilities so that one machine can handle Stick, MIG, TIG, FCAW, arc gouging and even pulsing.
Inverters can also save money in energy costs over traditional-type power sources since:
Greater transformer efficiencies are realized through the use of ferrite cores in the inverter's power transformer. This reduces the current losses resulting in lower idle currents in the supply conductors.
The inverter transformer coils are physically smaller than common transformers. A smaller coil translates to less wire wrapping around the core - less wire means fewer losses and greater efficiency.
The inverter's power electronic components have been carefully designed to reduce losses and extend operating life.
Many inverters use a copper conductor. Copper has higher thermal and electrical conductivity compared to aluminum, which will minimize losses and maximize efficiency.
Operating at higher frequencies than conventional welders, inverters require less output inductance for smooth operation. The energy needed for stick welding or for globular transfer welding processes is stored in capacitors allowing for smaller output chokes.
The compact design and relatively small physical size of an inverter welder means shorter leads and cables (or even direct connections) between power components. Shorter current paths translate to lower resistances and better efficiencies.
Because the inverter is designed to inherently have low losses, smaller cooling fans are required. This means less power is needed for moving cooling air and, again, greater efficiency.
The smaller size of the components inside the inverter machine translate into less heat to dissipate and again, greater efficiency
Jimmy Jammer
 -  Semi-Automatic Welding System composed of a manipulator, weld oscillator (oscillating welding torch), cross slide, positioner and turning rolls. The semi-automatic weld oscillator controls the positioners and turning rolls.
Joined buildup sequence
 -  The order in which the weld beads of a multiple-pass weld are deposited with respect to the cross section of the joint.
Joint
 -  The junction of members or the edges of members which are to be joined or have been joined.
Joint clearance
 -  The distance between the faying surfaces of a joint. In brazing this distance is referred to as that which is present either before brazing, at the brazing temperature, or after brazing is completed.
Joint design
 -  The joint geometry together with the required dimensions of the welded joint.
Joint efficiency
 -  The ratio of the strength of a joint to the strength of the base metal (expressed in percent).
Joint geometry
 -  The shape and dimensions of a joint in cross section prior to welding.
Joint penetration
 -  The minimum depth a groove or flange weld extends from its face into a joint, exclusive of reinforcement. Joint penetration may include root penetration.
Joint welding procedure
 -  The materials, detailed methods and practices employed in the welding of a particular joint.
Kerf
 -  The width of the cut produced during a cutting process.
Keyhole TIG
 -  A high speed, full penetration GTAW welding technology that offers enormous productivity, cost and quality advantages over existing processes in stainless steels and other corrosion resistant materials.

Kilogram (kg)
 -  The kilogram or kilogramme (SI unit symbol: kg) is the base unit of mass in the International System of Units (SI). 1 Kilogram = 2.2 pounds | 1 pound = 0.453592 Kilograms.
kVA (1,000 volt-amps)
 -  A kVA is 1,000 volt-amps. It's what you get when you multiply the voltage (the force that moves electrons around a circuit) by the amps (electrical current). Kilovolt-amps measure what's called the 'apparent power' of a generator. This is different from kilowatts (kW), which measure the 'true power'. kW is the amount of 'actual power' an electrical system has. This shows you how much power is being converted into useful, working output. kVA, on the other hand is the measure of 'apparent' power. If kW is how much power you can work with, kVA tells you how much is being used in the system overall.
kW (Kilowatts)
 -  A kilowatt is simply 1,000 watts, which is a measure of power. Primary kW is the actual power used by a power source when it is producing its rated output. Secondary kW is the actual power output of a welding power source. Kilowatts are found by taking volts times amps divided by 1,000 and taking into account any power factor.
Lap joint
 -  A joint between two overlapping members.
Layer
 -  A stratum of weld metal or surfacing material. The layer may consist of one or more weld beads laid side by side.
Leg of a fillet weld
 -  The distance from the root of the joint to the toe of the fillet weld.
Lightly coated electrode
 -  A filler metal electrode consisting of a metal wire with a light coating applied subsequent to the drawing operation, primarily for stabilizing the arc.

Lincoln Chopper Technology
 -  Lincoln Electric’s Chopper Technology is the simplest form of high frequency power conversion. A chopper is composed of a transistor switch and a diode. DC input power is “chopped” to a lower output voltage, and a choke is placed in the path of the output to smooth current variation. Choppers were developed for engine driven welders to offer the same control over the welding arc as the inverter machines. This allows more consistent arc performance across product lines. Choppers are ideal for the customer searching for an inexpensive option for low cost, high quality arc performance.

Lincoln Inverter Technology
 -  Lincoln inverter-based welding power sources operate at frequencies above 20 kHz, whereas traditional power sources operate at a line frequency of 50 or 60 Hz. Some of the advantages an inverter has are smaller magnetic components (chokes and transformers), higher efficiency, and a fast response to the welding arc. Inverter power sources were first introduced into the welding industry in the early 1980s. The initial attraction of the inverter was its small size and easy portability. For example, a rectifier-based machine, could weigh as much as four times that of an inverter-based machine. Less space is needed and the inverter unit is easily moved around the job site. As the popularity and reliability of the inverter increased, the capabilities were expanded. Inverters are now designed for many different processes: SMAW, GTAW, FCAW, SAW, and are capable of operating in extreme environments. Over the last decade, Lincoln Electric has invested heavily in developing inverter technology, producing highly reliable inverter machines.

This gives Micro-Start TIG very stable low current welding and provides it with the ability to eliminate erratic high frequency and weld thin materials in a consistent, high quality manner. Lincoln is the first manufacturer to offer a background circuit from which an operator can weld and smoothly transition to, or from, higher outputs. Micro-Start TIG is capable of independently welding off of its electronic power supply when the amperage is down to the minimum rated 2 amps. As the operator depresses the foot Amptrol™ to increase the current, the main welding circuit (i.e. transformer and SCR bridge) turns on and provides amperage. The technology assists the transformer SCR choke circuit with its special electronic welding circuit instead of completely relying on chokes to smooth the arc as do conventional machines. The result is a very stable and smooth output at low amperage levels. With Micro-Start TIG, operators don’t have to buy more expensive machines to get low end welding capabilities – Micro-Start technology is able to provide inverter-like performance using a lower cost, conventional machine. With Lincoln’s Micro-Start TIG technology, an operator at virtually any TIG skill level will be able to make repeatable, high-quality starts, welds and finishes. This is because the new technology makes it easy to overcome the most common TIG welding issues with machines that overcome the most common performance limitations.
Lincoln Micro-Start™ II Technology
 -  Micro-Start II provides the operator with the ability to weld at lower DC amperages and “feather out” to as low as 2-5 amps at the end of the weld. Also, once the high frequency initiates the DC arc, the control circuit prevents the high frequency from coming on again during crater fill. In effect, the high frequency is no longer needed because Micro-Start technology provides tremendous low amperage stability for the machine. With Micro-Start II technology (found on Lincoln Precision TIG welders), Lincoln Electric has devised a way to get the arc established more quickly, more smoothly and with greater stability. It does this using an electronic low amp welding power supply to supplement the main power supply. The starting circuit offers just enough energy to heat the tungsten and establish a more stable plasma flow to the work piece. This starting sequence is short and provides precise control over starting conditions. In effect, Micro-Start II technology is so effective that most operators cannot detect that the high frequency was used during starting. In many traditional, low amperage TIG applications, operators have trouble maintaining a smooth, stable arc. This is because the machine's choke cannot store enough energy between SCR firings to stabilize the arc. The resultant ‘ripple effect’ creates arc instability, which may result in arc outages followed by high-frequency arc re-initiations. These erratic outages can lead to inconsistencies in the weld. Micro-Start TIG utilizes a separate electronic power supply to establish an arc and weld at the Precision TIG minimum rated amps. When the operator first depresses the foot pedal, this separate power supply starts and welds independently of the Precision TIG main welding circuit (i.e. transformer and SCR bridge). As the operator further depresses the foot pedal to increase the current, the main welding circuit turns on and provides additional amperage. Unlike conventional machines, which rely completely on the SCR choke, Micro-Start technology’s special electronic welding circuit assists the transformer SCR choke circuit by delivering smooth power to the arc. This gives the Precision TIG very stable low-current welding capability and provides the customer with the ability to weld thin materials in a consistent, high-quality manner.

Lincoln Synchronized Tandem MIG®
 -  Lincoln Electric technology which overcomes deposition rate limitations of a single wire by using two wires and specific waveforms. The result is nearly double deposition rates and faster travel speeds.
Lincoln TVT™ True Voltage Technology™ voltage drop compensation
 -  In many outdoor welding applications the operator can be located hundreds of feet away from the power source. All that cable can create a difference in voltage, or voltage drop, between the power source and the weld. For example, if 24 volts is set on the welding power source, as a result of electrical resistance through the cables, only 20 volts may actually be available at the wire feeder. This would result in a cold weld. True Voltage Technology (TVT) calculates this drop and gives the true voltage set at the wire feeder by adjusting the power source to compensate for the voltage drop. In this example, 24 volts is preset at the wire feeder. TVT senses there is a 4 volt drop due to long weld cables and compensates by increasing the welder power source output to 28 volts. The result is that the desired 24 volt is available at the welding arc.

 -  MIG is an acronym for Metal-Inert-Gas, also known as GMAW or Gas Metal Arc Welding. This arc welding process uses a spooled, continuously fed filler metal (consumable) electrode. Shielding is provided by externally supplied gas or gas mixtures. Easiest process to learn, High welding speeds possible, Provides better control on thinner metals, Cleaner welds possible with no slag, Same equipment can be used for flux-cored welding. For welding steel, stainless steel, nickel alloys, aluminium, copper/brass. Learn More about: Aluminum MIG Welding, MIG Packages, MIG Wirefeeder Welders, Miller MIG Welders Lincoln MIG Welders
MIG/MAG GMAW Welding
 -  MIG stands for Metal Inert Gas. Only inert gases or gas mixtures are used for the shielding gas when MIG welding. Typical inert gases used for MIG welding are argon and helium. These gases are usually used for MIG welding of aluminium and other non-ferrous metals. MAG stands for Metal Active Gas. Active gas mixtures have been developed primarily for welding steels. Typical shielding gases are mixtures of argon, carbon dioxide and oxygen e.g. CO2 , Ar + 2 to 5% O2 , Ar + 5 to 25% CO2 and Ar + 10% CO2 + 5% O 2 . The composition of the shielding gas has a substantial effect on the stability of the arc, metal transfer and the amount of spatter. The shielding gas also affects the behaviour of the weld pool, particularly its penetration and the mechanical properties of the welded joint. In the US, both MIG and MAG welding are described by the term GMAW (Gas Metal Arc Welding).

Paralleling
 -  Running multiple power generators to form a large capacity power source with redundancy. Often used for mission critical operations such as oilfield and emergency backup power. More about paralleling generators.
Partial joint penetration
 -  Joint penetration which is less than complete.
Pass
 -  A single progression of a welding or surfacing operation along a joint, weld deposit, or substrate. The result of a pass is a weld bead, layer, or spray deposit.
Peel test
 -  A destructive method of inspection which mechanically separates a lap joint by peeling.
Peening
 -  The mechanical working of metals using impact blows.
Plano lens (eye protection)
 -  A lens which does not incorporate correction.
Plasma
 -  A gas that has been heated to an at least partially ionized condition, enabling it to conduct an electric current.
Plasma Arc Welding (PAW)
 -  An arc welding process which produces coalescence of metals by heating them with a constricted arc between an electrode and the workpiece (transferred arc) or the electrode and the constricting nozzle (non transferred arc). Shielding is obtained from the hot, ionized gas issuing from the orifice which may be supplemented by an auxiliary source of shielding gas. Shielding gas may be an inert gas or a mixture of gases. Pressure may or may not be used, and filler metal may or may not be supplied. View all Plasma Cutters
Plug weld
 -  A circular weld made through a hole in one member of a lap or T-joint fusing that member to the other. The walls of the hole may or may not be parallel and the hole may be partially or completely filled with weld metal. (A fillet welded hole or a spot weld should not be construed as conforming to this definition.)
Polarity
 -  Electrode welding polarity affects the penetration level of the weld. With most arc welding processes, DC+ (direct current electrode positive) polarity produces more weld penetration, because more arc energy is focused into the base plate. Conversely, DC- (direct current electrode negative) polarity produces less weld penetration, because more arc energy is focused into the electrode and not into the base plate. This is the case with the shielded metal arc welding (SMAW), gas metal arc welding (GMAW), flux cored arc welding (FCAW) and SAW processes. The exception is the gas tungsten arc welding (GTAW) process, in which the effect of polarity on penetration is opposite. With GTAW, DC- polarity results in more weld penetration (with DC+ polarity generally not used).
Porosity
 -  Cavity type discontinuities formed by gas entrapment during solidification.
Positioned weld
 -  a weld made in a joint which has been so placed as to facilitate making the weld. See: welding positioners.
Postheating
 -  The application of heat to an assembly after a welding, brazing, soldering, thermal spraying or cutting operation.
Postweld heat treatment
 -  Any heat treatment subsequent to welding.
Pounds Per Square Inch (psi)
 -  A measurement equal to a mass or weight applied to one square inch of surface area.
Power Efficiency
 -  How well an electrical machine uses the incoming electrical power.
Power Factor Correction
 -  Normally used on single-phase, constant current power sources to reduce the amount of primary amperage demanded from the power company while welding.
Preheat temperature
 -  A specified temperature that the base metal must attain in the welding, brazing soldering, thermal spraying, or cutting area immediately before these operations are performed.
Preheating
 -  The application of heat to the base metal immediately before welding, brazing, soldering, thermal spraying, or cutting. See > Induction Heating Equipment Used for Preheating
Primary Power
 -  Often referred to as the input line voltage and amperage available to the welding machine from the shop's main power line. Often expressed in watts or kilowatts (kW), primary input power is AC and may be single-phase or three-phase.
Prime power generator rating
 -  Prime power ratings can be defined as having an “unlimited run time”, or essentially a generator that will be used as a primary power source and not just for standby or backup power.
Procedure
 -  The detailed elements (with prescribed values or ranges of values) of a process or method used to produce a specific result.
Procedure qualification
 -  The demonstration that welds made by a specific procedure can meet prescribed standards.
Progressive block sequence
 -  A block sequence during which successive blocks are completed progressively along the joint, either from one end to the other or from the center of the joint toward either end.
Protective atmosphere
 -  A gas envelope surrounding the part to be brazed, welded or thermal sprayed, with the gas composition controlled with respect to chemical composition, dew point, pressure, flow rate, etc. Example are inert gases, combusted fuel gases, hydrogen and vacuum.
Pulse
 -  A current of controlled duration through a welding circuit.
Pulse time
 -  The duration of a pulse.
Pulsed MIG (GMAW-P)
 -  A modified spray transfer process that produces no spatter, because the wire does not touch the weld puddle. Applications best suited for pulsed MIG are those currently using the short circuit transfer method for welding steel, 14 gauge (1.8 mm) and up. Flexibility and productivity—nearly all metals can be welded in all positions, Larger diameter electrode wires for higher deposition rates, Virtually no spatter, Welds thin to thick metalsArticle: Why Use Pulsed MIG?
Pulsed power welding
 -  Any arc welding method in which the power is cyclically programmed to pulse so that effective but short duration values of a parameter can be utilized. Such short duration values are significantly different from the average value of the parameter. Equivalent terms are pulsed voltage or pulsed current welding: see also pulsed spray welding.
Pulsed spray welding
 -  An arc welding method in which the current in pulsed to utilize the advantages of the spray mode of metal transfer at average currents equal to or less than the globular to spray transition current.
Pulsing
 -  Sequencing and controlling the amount of current, the frequency and the duration of the welding arc.
Push Angle
 -  The travel angle when the electrode is pointing in the direction of travel. Defines the position of welding guns, welding torches, high energy beams, welding rods, thermal cutting and thermal spraying torches, and thermal spraying guns in a forward direction.
Quality Assurance (QA)
 -  The practice of using a set of defined processes for systematic monitoring and evaluation to assure product quality. See Welding Quality Assurance & Quality Control Processes
Quality Control (QC)
 -  The process of confirming that a product meets an established set of specifications. See Welding Quality Assurance & Quality Control Processes
Rated Load
 -  The amperage and voltage the power source is designed to produce for a given specific duty cycle period. For example, 300 amps, 32 load volts, at 60 percent duty cycle.

TIG Arc Starting Techniques
 -  Lift TIG - Developed as alternative to “scratch starts” or high-frequency (HF) arc starts, Lift TIG provides consistent, positive arc starts for welding with a DC output. There were two primary reasons to develop Lift TIG. First, HF current can interfere with electronics, including laptop computers and CNC machinery. Second, the scratch start technique, where the operator scratched the tip of the tungsten on a work-piece with a motion similar to that of striking a match, could contaminate the weld with tungsten particles. In a critical application, arc starts would need to be ground out and rewelded. Lift TIG completely eliminates issue associated with HF and, when executed properly, almost entirely eliminates the risk of tungsten inclusions. When people get frustrated with a Lift TIG unit, most of the time it’s because they are trying to use a scratch start technique. It’s critical that you just lightly touch, not scratch, the tungsten to the work piece, as well as hold it there for a second before lifting the TIG torch.
/High Frequency (HF) Capabilities - Note that Lift TIG is not acceptable for welding procedures that specify a non-contact arc starting method, as is often the case with pressure vessels and process piping. Here, you need a welding system that provides HF arc starts, which typically results in people asking, “How come unit X, Y or Z doesn’t have HF capabilities?” The simple answer is that ESAB and the other manufacturers do have units specifically designed to provide HF TIG arc starts. Going beyond that, it might help to understand that HF is a High-Voltage, Low Current, high RF frequency that is induced onto the welding lead. Incorporating HF components adds hundreds of dollars in cost to a power source, and not every customer wants to pay for functionality they don’t plan to use. That’s why equipment manufacturers offer Lift TIG-only power sources only and power sources with both Lift TIG and HF TIG arc starts. For more information visit www.esab.com

Travel angle (pipe)
 -  The angle that the electrode makes with a reference line extending from the center of the pipe through the puddle in the plane of the weld axis.
Travel angle of welding electrode
 -  The degree of the travel angle, whether a push or drag travel angle, affects how much of the arc force is directed down into the base plate. A travel angle of 0° to 10° (e.g.the electrode perpendicular or almost perpendicular to the plate) will result in more weld penetration. As the travel angle is increased, the level of weld penetration decreases.

 -  An automatic electrical control device for maintaining a constant voltage supply to the primary of a welding transformer.
Voltage sensing wire feeders
 -  Voltage sensing wire feeders (also referred to as across-the-arc wire feeders) operate on arc voltage, eliminating the need for a control cord between the power source and the wire feeder. A voltage sensing wire feeder can be paired with either a constant voltage (CV) or a constant current (CC) power source. These feeders typically have a CC/CV switch inside the case. With a voltage sensing wire feeder and CV power source, voltage is set at the power source while wire feed speed (amperage) is set at the feeder. This can present a headache when working remotely from the power source, such as up on scaffolding and when you need to adjust voltage. Also, because voltage varies directly with distance between the electrode and the work piece (arc length), the feeder attempts to regulate voltage variations (e.g., an unsteady hand) by controlling wire feed speed. This means your parameters can vary slightly. Many engineering firms, construction companies and building codes no longer allow flux cored welding (FCAW) with a CC power source. It does not provide adequate assurance that the weld is being made with the proper voltage because operators must hunt for a voltage because the voltage fluxuates on a volt/amp curve from the CC power source. Instead, experts recommend a CV power source for wire welding, especially for the nickel-alloy and other flux cored wires used for structural welds on buildings and bridges. These wires are very voltage sensitive and generally require the fine-tuning capabilities of a CV machine.

Welding machine
 -  Equipment used to perform the welding operation. For example, spot welding machine, arc welding machine, seam welding machine, etc.
Welding operator
 -  One who operates machine or automatic welding equipment.
Welding procedure
 -  The detailed methods and practices including all joint welding procedures involved in the production of a weldment.
Welding process
 -  A materials joining process which produces coalescence of materials by heating them to suitable temperatures, with or without the application of pressure or by the application of pressure alone, and with or without the use of filler metal.
Welding rectifier
 -  A device in a welding machine for converting alternating current to direct current.
Welding rod
 -  A form of filler metal used for welding or brazing which does not conduct the electrical current.
Welding sequence
 -  The order of making the welds in a weldment.
Welding technique
 -  The details of a welding procedure which are controlled by the welder or welding operator.
Weldment
 -  An assembly whose component parts are joined by welding.
Wet-stacking on diesel engines
 -  Unburned fuel and engine oil collecting in the exhaust stack of a diesel engine, characterized by the exhaust stack being coated with a black, sticky, oily substance. The condition is caused by the engine being run at too light of a load for extended periods of time. Caught early, this does not cause permanent damage and can be alleviated if additional load is applied. If ignored, permanent damage can occur to the cylinder walls and piston rings. Improved emission standards and higher quality fuel make engines less prone to wet-stacking in recent years.
Wetting
 -  The bonding or spreading of a liquid filler metal or flux on a solid base metal.
What is VRD?
 -  VRD stands for voltage reduction device. When VRD is included in the design of a welding machine it reduces the maximum unloaded open circuit voltage (OCV) across the output terminals of a welding machine to a safe voltage. Normally this reduced voltage is about 12 volts. When a load of less than 200 ohms resistance is applied to the output of the welding machine, the VRD will sense this resistance and adjust the welder to full output so that the welding arc can be established and welding commenced. When the resistance across the output rises above 200 ohms, or the electrode is removed from the workpiece, then VRD will adjust the output of the welder back to a reduced output state. Why is this necessary? A lot of new welders, and some older units, have an open circuit voltage in excess of 105 volts DC or 85 volts AC. This voltage may be legal, and in normal (dry) conditions may be quite safe. The problem is that many sites have "abnormal" (e.g. damp, wet, caustic, salty conditions, high or confined space) working conditions, and an electric shock in these situations can be hazardous to the operator including dangers due to ventricular fibrillation, falling from heights, and inability to escape the power source when in confined spaces, not to mention the serious physical injuries sustained as a secondary result of an electric shock. Electric shock from a welder power source can also cause serious internal injuries to the human body which are not always immediately noticeable. On some welders, such as Red-D-Arc's FX500XL, the VRD™ functionality must be set manually via internal switches on the machine, and in the case of the FX500XL, only operates in CC-Stick mode. From the FX500XL IM Manual: "The VRD™ feature provides additional safety in the CC-Stick mode. The VRD™ reduces the OCV (Open Circuit Voltage) at the welding output terminals while not welding to less than 35VDC peak. The VRD™ requires that the welding cable connections be kept in good electrical condition because poor connections will contribute to poor (arc) starting. Having good electrical connections also limits the possibility of other safety issues such as heat-generated damage, burns and fires. The machine is shipped with VRD™ “Disabled”. The VRD™ function can be disabled or enabled via dip switches on the user interface P.C. board. The user interface board and dip switches can be accessed by removing the case top and side as shown in Internal Controls section."
Wire feed speed
 -  The rate of speed in mm/s* or in./min at which a filler metal is consumed in arc welding. *Note: In Canada this is expressed in mm/min.
Wire straightener
 -  A device used for controlling the cast of coiled wire to enable it to be easily fed in to the gun.
Work angle
 -  The angle that the electrode makes with the referenced plane or surface of the base metal in a plane perpendicular to the axis of the weld.
Work connection
 -  The connection of the work lead to the work.
Work lead
 -  The electric conductor between the source of arc welding current and the work.
