DC TIG Features

  • Pulse. Pulsing can increase puddle agitation, arc stability and travel speeds while reducing the heat input and distortion. DX models provide extended ranges.
  • Exceptionally smooth and precise arc for welding materials.

DC Stick Features

  • DIG control allows the arc characteristics to be changed for specific applications and electrodes. Lower DIG setting for smooth running electrodes like E7018 and increase the DIG setting for stiffer, more penetrating electrodes like E66010.
  • Hot Start adaptive control provides positive arc starts without sticking.
  • Stick-Stuck detects if the electrode is stuck to the part and turns the welding output off to safety and easliy remove the electrode. Menu selectable.

Pro Set

Eliminates the guesswork when setting the weld parameters. Use Pro-Set when you want the speed, convenience and confidence of preset controls. Simply select the feature and adjust until Pro-Set appears on display.

Blue Lightning

Blue lightning high frequency (HF) arc starter for non-contact arc starts and greater reliability compared to traditional HF arc starters.

Update & Expand

Front panel memory data card port provides the ability to easily update software and expand product features.

Sleep Timer

The sleep times conserves electricity. This programmable feature will power down the machine if it sits is idle for a specified time.


Variable speed fan adjusts to match cooling requirements, reducing noise, energy use and the amount of contaminants pulled through the machine.

Auto-Line Power Management Technology

Allows for any input Voltage hookup (240-480 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power.

Rated for use from 15 Amp Plug

Wind Tunnel Technology

Protects internal components from airborne contaminates, extending product life.

3 Year Warranty

For details, refer to Miller's True Blue Warranty statement.
