1 Material Switch
!Do not use AC output in
damp areas, if movement is
confined, or if there is dan-
ger of falling. Use AC output
ONLY if required for the
welding process, and then
use a remote control.
!Do not change position of
switch while welding or
while under load.
Use switch to select DC for steel,
stainless steel, and chrome-moly,
or AC for aluminum applications.
2 Material Thickness/Amperage
Control
Use control to select material thick-
ness and corresponding amper-
age.
When Material switch is in the DC
position, use the blue scale to se-
lect the appropriate material thick-
ness and corresponding amperage
from the white scale. When Material
switch is in the AC position, use the
gray scale to select the appropriate
material thickness and correspond-
ing amperage from the white scale.
Set maximum desired amperage.
The maximum amperage available
when using the foot control will be
the value the Amperage control dial
is set at.
3 Foot Control
Press pedal lightly to turn weld
output and gas flow on. Press pedal
further to increase weld output.
Raise pedal to reduce amperage,
crater-out, and turn off weld output
and gas flow.
