Prepare unit for welding wire load-
ing as follows:
S Install wire spool and adjust hub
tension (see Section 4-2).
S Use proper drive rolls and wire
guide (see Section 4-6).
S Thread welding wire and adjust

Without starting a weld, press and
hold for three seconds the torch
trigger 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 parts
during wire loading. Welding
wire will be loaded at a wire
feed speed value of about 11
meters per minute (mpm). The
wire feed speed is only meas-
ured in meters per minute.
To stop loading wire, release torch
trigger.
