Use switch to select weld process and
weld output on/off control (see table be-
low and Section 7-4).
Place switch in Remote positions to turn
weld output on and off with a device con-
nected to the remote 14 receptacle.
Place switch in Electrode Hot positions
for weld output to be on whenever the en-
gine is running.
Use Stick position for air carbon arc
(CAC-A) cutting and gouging.
When switch is in a Stick position, the arc
drive (dig) circuit provides additional am-
perage during low voltage (short arc
length conditions) to prevent "sticking"
electrodes.
The arc drive (dig) circuit is disabled
when switch is in MIG or TIG positions.
