DC TIG Features

  • Exceptionally smooth and precise arc
  • High-Speed DC TIG Pulse Controls

DC Stick Features

  • Tailored arc controls (DIG)
  • Hot Start™

Auto-Line™ allows for any input voltage hook-up (208-575 V) with no manual linking, providing convenience in any job setting.

120 V auxiliary power receptacle for cooling system or small tools.

Program memory features 9 independent program memories that maintain/save your parameters.

Programmable start parameters allow the operator to independently set starting conditions based upon process and memory selections (amperage and time).

Superior TIG/Stick arc performance on all input voltages. Even on the difficult to run electrodes like E6010.

HF arc starting provides non-contact arc starting that eliminates tungsten or material contamination.

Auto-Postflow calculates the length of postflow time based on the amperage setting. This eliminates the need to independently set the postflow time for different amperages. This feature preserves your tungsten and prevents porosity.

Lift-Arc™ start provides TIG arc starting without the use of high frequency.

Fan-On-Demand™ only operates when needed — reducing noise, power consumption, and the amount of airborne contaminants pulled through the machine.

Wind Tunnel Technology™ is an Internal air flow that protects electrical components and PC boards from dirt, dust, and debris, greatly improving reliability.

LVC™ Line Voltage Compensation
keeps output of the power source constant regardless of fluctuation in input power ± 10%.

Optional TIGRunner® Packages feature a 3.5 gallon coolant system, foot pedal current/contactor control, and cart with cylinder rack, cable holders, and extra storage space.

Optional Automation Interface Kit (#195 516) includes automation PC board, 28-pin socket receptacle with harness, and 28-pin plug connector. Provides required and advanced automation controls.
