position and the engine is run-

 

ning.

Y DC voltage is still present at the

 

weld terminals when Process/

 

Contactor switch is in the

 

Remote − 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 7-4).

Place switch in Remote positions to turn weld output on and off with a de- vice connected to the remote 14 recep- tacle.

Place switch in Electrode Hot 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.

. Place switch in Electrode Hot - Stick position when using optional three-phase generator (see Sec- tion 8-2).

. The engine auto idle option does not work in the Remote-TIG mode.
