Process/Contactor Switch Settings | Miller Electric Big Blue 452P

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

1	Process/Contactor Switch
Y Weld output terminals are ener-
	gized when Process/Contactor
1	switch is in an Electrode Hot
	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.
