Use switch to select weld process
and weld output on/off control (see
table below and Section 6-4).
Place switch in Remote positions to
turn weld output on and off with a de-
vice connected to the remote 14 re-
ceptacle.
Place switch in Electrode Hot posi-
tions for weld output to be on whenev-
er the engine 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 addi-
tional amperage during low voltage
(short arc length conditions) to pre-
vent "sticking" electrodes.
The arc drive (dig) circuit is disabled
when switch is in MIG or TIG
positions.
