 -  A mixture of metallic elements combined to provide specific properties such as greater resistance to corrosion or improved strength. For example, brass is an alloy of copper and zinc; steel is an alloy of iron and carbon.

 -  Power source only. 575 V with auxiliary power

 -  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 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.

The molten weld pool is shielded by this slag which moves along the full cross-section of the joint as welding progresses. The process is initiated by an arc which heats the slag. The arc is then extinguished and the conductive slag is maintained in a molten condition by its resistance to electric current passing between the electrode and the work.

 -  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

 -  Micro-Start TIG technology employs an independent power supply capable of welding without SCR assistance at low amperages – SCRs only fire to raise the current and supplement the 2 amp welding supply. 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.

Indicator lights will also signal when output voltage during welding is above or below 30 volts DC.

 -  The principal bond which holds metals together and which is formed between base metals and filler metals in all welding processes. This is a primary bond arising from the increased spatial extension of the valence electron wave functions when an aggregate of metal atoms is brought close together.

 -  One or more integrated circuits that can be programmed with stored instructions to perform a variety of functions.

 -  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).
