6-2. Process/Contactor Switch On CC/CV Models
1 Process/Contactor Switch
Y Weld output terminals are ener-
gized when Process/Contactor
switch is in an Electrode Hot posi-
tion and the engine is running.
. The unit will not return to idle speed
when Process/Contactor switch is in
a Wire or TIG mode and the remote
contactor is on (closure between
pins A and B on remote receptacle).
Use switch to select weld process and
weld output on/off control (see table be-
low and Section 5-9).
Place switch in Remote positions to turn
weld output on and off with a device con-
nected to the remote receptacle.
Place switch in Electrode Hot positions
for weld output to be on whenever the en-
gine is running.
Use Stick positions for air carbon arc
(CAC-A) cutting and gouging.
When switch is in a Stick position, the dig
circuit provides additional amperage
during low voltage (short arc length con-
ditions) to prevent “sticking” electrodes.
The dig circuit is disabled when switch is
in Wire or TIG positions.
