Main Features

  • NEW! Coolmate ™ 3X cooler TIGRunner option features a 3-gallon cooling system. A flow indicator provides visual indication that the system is working. The Coolmate 3X is also equipped with an external filter to stop any foreign objects from entering the water-cooled torch cable for better flow and longer life.
  • NEW! Syncrowave 350 LX TIGRunner Complete! Now includes EZ Load™ Cylinder Rack, 4 gallons of coolant, and a water-cooled torch kit.
  • Syncro Start™ for customized arc starts allows the operator to choose from three different starting conditions to optimize the application according to tungsten diameter and material thickness.
  • Squarewave output with AC balance control features adjustable penetration and cleaning action while increasing arc stability on various aluminum alloys, and helps eliminate tungsten spitting and arc rectification.
  • Dual digital meters allow for quick and easy viewing of actual and preset values of amperage and voltage.
  • Last procedure recall automatically recalls the last procedure set-up when switching polarity.
  • Built-in preflow/postflow provides 0 - 10 seconds of preflow and 0 - 50 seconds of postflow.
  • Built-in consumable storage located on the front panel allows the operator to store and readily access the needed consumables to be more productive.
  • Fan-On-Demand™ operates only when needed reducing noise, power consumption, and the amount of airborne contaminants pulled through the machine.
  • Lift-Arc™ start provides TIG arc starting without the use of high frequency.
  • LVC™ keeps output of the power source constant regardless of fluctuation in input power ± 10%.
  • Adaptive Hot Start™ for Stick Automatically increases output amperage at the start of a weld should the start require it and prevents the electrode from sticking and creating an inclusion.
