Welding Wire Loading Settings - Miller Electric MPi 220P Owner's Manual

5-13. Welding Wire Loading Settings

Prepare unit for welding wire load-
ing as follows:
S Install wire spool and adjust hub
tension (see Section 4-7).
S Use proper drive rolls and wire
guide (see Section 4-8).
S Thread welding wire and adjust
pressure roll tension (see Section
4-12).
Without starting a weld, press and
hold torch trigger for three seconds
to load welding wire.
.
After pressing and holding the
torch trigger, gas valve and in-
put power contactor are dis-
abled. This method prevents
the risks of arc ignitions due to
contact with conductive sur-
faces during wire loading.
Welding wire will be loaded at a
wire feed value of about 11
mpm. The wire feed speed is
only measured in meters per
minute.
To stop loading wire, release torch
trigger.
