  • Hot Start™
  • AC frequency control

Main Features

  • Auto-Line™ - Allows for any input voltage hook-up (208-575 V) with no manual linking, providing convenience in any job setting.
  • HF arc starting provides non-contact arc starting that eliminates tungsten or material contamination.
  • Superior Arc Performance- Smooth running 7018 or stiffer, more penetrating 6010.
  • Fan-On-Demand™ cooling system only operates when needed.
  • 120 V auxiliary power receptacle for cooling system or small tools.
  • Programmable start parameters allow independent starting conditions based on process and memory selections (amperage, time, and polarity.
  • Extended Balance Control range (30-90% EN) allows precise cleaning control and prolonged tungsten life.
  • Lift-Arc™ start provides TIG arc starting without the use of high frequency.
  • Wind Tunnel Technology™ is an Internal air flow that protects electrical components and PC boards from dirt, dust, and debris, greatly improving reliability.
  • Program memory features 9 independent program memories that maintain/save your parameters.
  • 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 porisity.
  • TIGRunner™ packages feature a 3.5 gallon cooling system. The cart is equipped with cylinder-carrying capabilities, filler rod holder, foot pedal holder, torch, and cable holders. A pullout drawer provides additional storage for torch consumables and tools.
