Additional Features

Description
The GX300 is a 305 amp DC, multiprocess, 100% duty cycle, gasoline engine-driven welder with 10,000 watts peak (9,500 watts continuous) 120/240 VAC 60 Hz auxiliary power. Rugged and reliable, the GX300 welder is built to Extreme-Duty specs with a completely enclosed case and is available with an optional protective frame with base that will accept a 3-wheel shop wheel kit. With an optional adapter, the frame with base can also be mounted on a 3+3 construction trailer. Designed for welding professionals who demand a superior welding arc. CSA certified

Engine
Kohler OHV Command CH22, 2 cylinder, 4 cycle, air-cooled, 22 HP @ 3600 RPM, 41 cu in (674 cc) gasoline engine

Features

  • “Chopper Technology” delivers easy welding starts, smooth arc, low spatter and excellent weld bead appearance
  • Output Control is via a single, full-range, potentiometer-type output control (which eliminates output-selection taps)
  • Welding Mode selection includes CV-Wire, Downhill Pipe, CC-Stick and Touch Start Tig positions
  • Arc Control adjustment gives a softer, buttery arc or a more forceful, digging arc in CC-Stick welding mode and inductance/pinch control in CV-Wire welding mode
  • Built-in “hot start” for easier starts and restrikes, minimizing the electrode “sticking” to the work
  • Enhanced Downhill Pipe welding mode provides faster travel speeds - especially on fill passes
  • No high frequency is required with Touch Start Tig - you just lift the tungsten from the work to start the arc
  • When the torch is lifted at the end of weld, there is a voltage-sensing arc cutoff providing enhanced weld quality
  • Output at welding terminals can be switched to Weld Terminals On or Remotely Controlled
  • A Wire Feeder Voltmeter switch matches the polarity of the wire feeder-voltmeter to the polarity of the electrode
  • Remote output control is auto-activated when a remote control is plugged into a 3-pin MS connector and constant-speed wire feeders (such as the LN7) are controlled remotely via a 14-pin MS connector
  • An electric fuel pump assures consistent delivery in high altitude and warm ambient-temperature conditions
  • An engine hour-meter and an electric fuel-gauge mounted on the control panel are standard
  • The fully-enclosed sheet metal package results in a low 101.3 dB sound rating (Lwa) at rated load
  • Engine idle speed can be switched between High Idle and Auto Idle
