1 Process/Contactor Switch
Weld output terminals are ener-
gized when Process/Contactor
switch is in a Weld Terminals Al-
ways On position and the en-
gine is running.
DC voltage is still present at the
weld terminals when Process/
Contactor switch is in the Re-
mote On/Off Switch Required −
Stick position and the engine is
running.
Use switch to select weld process and
weld output on/off control (see table be-
low and Section 6-4).
Place switch in Remote On/Off Switch
Required positions to turn weld output
on and off with a device connected to
the remote 14 receptacle.
Place switch in Weld Terminals Always
On positions for weld output to be on
whenever 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 addition-
al amperage during low voltage (short
arc length conditions) to prevent “stick-
ing” electrodes.
The arc drive (dig) circuit is disabled
when switch is in MIG or TIG positions.
The engine auto idle option does
not work in the Remote On/Off
Switch Required-TIG mode.
