5 Mode Switch
Mode switch setting determines the process.
For Air Carbon Arc (CAC-A) cutting and goug-
ing, place switch in Stick position. For best re-
sults, place Arc Control in the maximum posi-
tion.
6 Arc Control
Control adjusts Dig when Stick mode is se-
lected on mode switch. When set towards
minimum, short-circuit amperage at low arc
voltage is the same as normal welding
amperage.
When set towards maximum, short-circuit
amperage is increased at low arc voltage to
assist with arc starts as well as reduce stick-
ing while welding.
Select setting best suited for application.
Control adjusts inductance when V-Sense
Feeder position is selected on the mode
switch. Inductance determines the “wetness”
of the weld puddle. When set towards maxi-
mum, “wetness” (puddle fluidity) increases.
When one of the TIG modes is selected, this
control is not functional.
