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.
