6-4. Process/Contactor Switch

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-

tion 6-9).

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.
