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.
