6-4. Process/Contactor Switch
1
Process/Contactor Switch
!
Weld output terminals are
energized when Process/
Contactor 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).
Place switch in Remote On/Off
Switch Required positions to turn
weld output on and off with a de-
vice connected to the Remote re-
ceptacle.
Place switch in Electrode Hot
positions for weld output to be on
whenever the engine is running.
Use the Lift-Arc TIG mode for TIG
(GTAW) welding using the Lift-Arc
TIG starting procedure (see Sec-
1
Ref. 277070-A
Process/Contactor Switch Setting
Typical Process Applications (DC Only)
OUTPUT ON
Output On – GMAW/FCAW (MIG)
MIG solid wire and dual shield flux core use a voltage sensing (VS) feeder that does not
require a control cable back to the welder/generator.
Output On – FCAW-S (Electrode
Negative)
FCAW (Flux Cored Arc Welding
−
self shielded) uses a voltage sensing (VS) feeder that
does not require a control cable back to the welder/generator.
Output On
−
SMAW (STICK XX18
and STICK XX10)
Stick welding with or without a remote amperage control. Strike an arc to start welding.
Output On – GTAW (Lift-Arc TIG)
Lift-Arc TIG: touch tungsten to work and lift to start welding. Uses circuitry internal to the
welder/generator to aid arc start. Can be used with or without a remote control. Auto
Crater option can be enabled/disabled using the Service Menu (see Section 6-5).
Output On – CAC-A (Air Carbon Arc
Gouging)
Gouging with or without a remote amperage control. Strike an arc to start gouging.
REMOTE ON/OFF REQUIRED
Remote ON/OFF Required - GTAW
(Remote TIG)
High Frequency TIG or Scratch Start TIG welding. High frequency TIG starting with re-
mote control allows remote On/Off and Amperage control. Another typical application is a
simple TIG rig with a remote control device.
Remote ON/OFF Required - SMAW
(Remote Stick)
Stick welding with RHC-14 control allows remote On/Off and Amperage control. This can
help eliminate accidental arc strikes.
Remote ON/OFF Required - GMAW/
FCAW (Remote MIG)
MIG solid wire and dual shield flux core using a constant speed feeder. Use feeders with
14-pin remote voltage control, or use a Spoolmatic 30A with WC24 control.
