SECTION 6 − OPERATION
Mode switch setting determines both the pro-
cess and output On/Off control (see Section
6-3).
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 at minimum,
short-clearing amperage at low arc voltage is
the same as normal welding amperage.
2
When set at maximum, short-clearing amper-
age is increased at low arc voltage to assist
with arc starts as well as reduce sticking while
welding.
Select setting best suited for application.
Control adjusts inductance when MIG or
FCAW − no gas is selected on the mode
switch. Inductance (0−100%) determines the
"wetness" of the weld puddle. When set to-
wards maximum, "wetness" (puddle fluidity)
increases.
When one of the TIG modes is selected, this
control is not functional.
