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.
