7-3. Process/Contactor Switch On CC/CV Models

1 Process/Contactor Switch

! Weld output terminals are ener- gized when Process/Contactor switch is in an Weld Terminals Always On position and the en- gine is running.

DC voltage is still present at the weld terminals when Process/ Contactor switch is in the Re- mote On/Off Switch Required − 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 On/Off Switch Required positions to turn weld output on and off with a device connected to the remote 14 receptacle.

Place switch in Weld Terminals Always On 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 Weld Terminals Al- ways On - Stick position when us- ing optional three-phase generator (see Section 8-2).

The engine auto idle option does not work in the Remote On/Off Switch Required-TIG mode.
