DC TIG Features

  • Exceptionally Smooth and Precise Arc. For welding exotic materials.
  • DC Pulse. Pulsing can increase puddle agitation, arc stability and travel speeds while reducing heat input and distortion.

DC Stick Features

  • DIG Control. Allows the arc characteristics to be changed for specific applications and electrodes. Lower the DIG setting for smooth running electrodes like E7018 and increase the DIG setting for stiffer, more penetrating electrodes like E6010.
  • Hot Start Adaptive Control. Provides positive arc starts without sticking.

Lift-Arc Starting

Provides AC or DC arc initiation without the use of high frequency.

Blue Lightning

High-frequency arc starter for non-contact arc initiation. Provides more consistent arc starts and greater reliability.

Fan-On-Demand

Power source cooling system operates only when needed - reducing noise, energy use and the amount of contaminants pulled through the machine.

Cooler-On-Demand

Operates the auxiliary cooling system only when needed, reducing noise, energy use, and airborne contaminants pulled through the cooler.

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 porosity.

Meter Calibration

Allows meters to be calibrated for certification.

Cooler Power Supply (CPS)

An integrated 120-volt dedicated-use receptacle for the Coolmate 3.5 TIG Torch water cooler.

Wind Tunnel Technology

Protects internal electrical components from airborne contaminants, extending the product life.
