The balance control is adjustable to provide

additional oxide removal (more cleaning) or less

cleaning based on the condition of the material

being welded. See pg 2 for more information on

this feature.

Syncro Start allows the choice of Soft, Standard

or Hot TIG starts based on the application, lead

lengths and tungsten size.

Dual inline high-frequency points provide

intense high frequency for arc starting and

stabilization. Internal machine components are

protected from HF interference with additional

grounding and filtering for extended product life.

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.

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.
