Output (Contactor) Switch; Pulser Switch - Miller Electric PC-300 Owner's Manual

4-9. Output (Contactor) Switch

4-10. Pulser Switch

This switch may be turned
On and Off while welding.
1 Output (Contactor) Switch
Use switch to select way of control-
ling unit output. Availability of open-
circuit voltage depends on the posi-
tion of the Pulser Control Output
(Contactor) switch and the position
of the welding power source Output
(Contactor) switch (see Section
1
4-8).
For front panel control, place switch
in On position.
For remote control, place switch in
Remote 14 position (see Section
3-4).
1 Pulser Switch
When this switch is in the On posi-
tion, the welding power source out-
put will pulse between the back-
ground and peak amperage set-
tings of this pulser control (see Sec-
tions 4-4 and 4-3).
When this switch is in the Off posi-
tion, the welding power source out-
put remains at peak amperage lev-
el.

This switch may be placed in either
the On or Off position before or dur-
ing welding. If placed in the On posi-
tion before welding, the output am-
perage may begin pulsing at either
the peak or background level. If
placed in the On position while
welding, pulsing begins at the peak
amperage level and pulses to the
background level.
