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 (0-100%) determines the
"wetness" of the weld puddle. When set to-
wards maximum, "wetness" (puddle fluidity)
increases.
For self-shielding wires (FCAW) adjust arc
control to FCAW setting.
When one of the TIG modes is selected, this
control is not functional.
