Squarewave technology

Squarewave technology was developed by Miller Electric in 1976 to improve your weld quality and make TIG welding easier. Miller Squarewave technology provides arc stability when welding aluminum, prevents arc rectification and eliminates tungsten erosion.

Syncro Start™

This allows the choice of Soft, Standard or Hot TIG starts based on the application, lead lengths and tungsten size.

Last procedure recall

Simplifies changing your Syncrowave back and forth from aluminum TIG to stainless TIG to Stick welding. One switch makes all the control panel changes.

Pulsed TIG control

This control lowers the heat input into the part and reduces warping and distortion.


Balance control

The balance control is adjustable to provide additional oxide removal (more cleaning) or lesscleaning based on the condition of the material being welded.


Digital welding meters

Display both amperage and voltage for viewing of the actual and preset values for greater accuracy and repeatability in your welding procedure.


Adaptive Hot Start™

Stick welding features such as Adaptive Hot Start™ provide good arc strikes without sticking. Once welding, the DIG control makes dynamic adjustments to the welder to ensure smooth E7018 and deep penetration E6010.

  • Features:
  • All-in-one design features a 3-year warranty- the first and ONLY cooler in the industry with a warranty beyond one year.
  • 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.
  • Last procedure recall automatically recalls the last procedure set-up when switching polarity. Prevents operator confusion and reduces training time requirements.
  • Built-in pulser provides a heating and cooling effect on the weld puddle to reduce the heat input and distortion of the material.
  • Dual digital meters allows for quick and easy viewing of actual and preset values of amperage and voltage.
  • Built-in preflow and postflow provides 0 - 10 seconds of preflow and 0 - 50 seconds of postflow.
  • Built-in cable hangers on both sides conveniently fold out of power supply to allow all weld cables to be neatly stored, to prevent torch or cable damage.
  • NEMA Class 1 Rating
  • Optional built-in sequencer allows the operator to set a start current that is highter or lower than the welding current.
  • Fan-On-Demand - Internal power source cooling system that only works when needed, keeping internal components cleaner.
  • LVC Line Voltage Compensation - Keeps output of the power source constant regardless of fluctuation in input power ± 10%.
  • Hot Start - Used on some Stick (SMAW) machines to make it easier to start difficult-to-start electrodes. Used for arc starting only.
  • Lift-Arc - Simply touch the tungsten to the work piece…lift…and the arc is initiated instantly and automatically.
  • Adaptive Hot Start for Stick - Automatically increases output amerage at the start of a weld should the start require it and prevents the electrode from sticking and creating an inclusion
