6-2. Process/Contactor Switch On CC/CV Models

11 Process/Contactor Switch

Y Weld output terminals are ener- gized when Process/Contactor switch is in an Electrode Hot posi- tion and the engine is running.

. The unit will not return to idle speed when Process/Contactor switch is in a Wire or TIG mode and the remote contactor is on (closure between pins A and B on remote receptacle).

Use switch to select weld process and weld output on/off control (see table be- low and Section 5-9).

Place switch in Remote positions to turn weld output on and off with a device con- nected to the remote receptacle.

Place switch in Electrode Hot positions for weld output to be on whenever the en- gine is running.

Use Stick positions for air carbon arc (CAC-A) cutting and gouging.

When switch is in a Stick position, the dig circuit provides additional amperage during low voltage (short arc length con- ditions) to prevent “sticking” electrodes.

The dig circuit is disabled when switch is in Wire or TIG positions.
