6-3. Process/Contactor Switch On CC/CV Models
1
1 Process/Contactor Switch
Y Weld output terminals are en-
ergized when Process/Con-
tactor switch is in an Electrode
Hot position and the engine is
running.
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.
. Place switch in Electrode Hot -
Stick position when using option-
al auxiliary power plant (see Sec-
tion 7-2).
. The engine auto idle function
does not work in the Remote-TIG
mode.
