3 AmperageNoltage Adjustment
Control
Control adjusts voltage with process switch
in
GMAW
position, and adjusts
amperage
in
SMAW and GTAW
positions.
Switch selects panel
or
remote control of
amperage/voltage level.
Ref. ST-165 852-B
6 Output (Contactor) Control Switch
Set control
at
0 for normal welding
amper
age. Turn clockwise to
increase short-cir
cuit amperage.
Switch selects panel On
or
remote
control of
output
On/Off.
4 Process Switch
short-circuit amperage
at
low
arc
voltage is
the
same as
normal welding
amperage.
When set towards
100,
short-circuit amper
age is increased
at low
arc
voltage to assist
with
arc
starts
as
well
as
reduce
sticking
while welding.

Switch selects
type
of weld
output.
Use
SMAW
position
for SMAW. Use GTAW posi
tion for GTAW, GMAW-P, and CAC-A. Use
GMAW position for GMAW, and FCAW.

Control Switch
Switch selects
panel
or
remote control of
arc
force/inductance.
8 Dig/Inductance Control
Control adjusts inductance with process
switch in GMAW. Inductance determines
the wetness of the weld puddle. When set
towards
100,
wetness (puddle fluidity)
increases.
This control is not functional with process
switch in GTAW.
Control adjusts dig with process switch in
SMAW
position.
When set towards 0 (zero),
Numbers around control
are
for reference
only.
