3.5 Based on the wire diameter select the correct groove. See the chart below for assistance.
When installing the drive roller, the number stamped on the drive roller for the wire size you are
using should be facing inward. Push the Drive Roller onto the Drive Roller Shaft.
3.7 Reinstall the Drive Roller knob and tighten clockwise.
3.8 Close the door to the welder drive compartment.
4. INSTALL THE WIRE - We recommend the usage of .023, .030, and .035 MIG wire, or .030, .035
and .040 flux core wire, on this unit.
4.1 Select welding wire - Both 8" and 11" wire spools of .023, .030, .035 and .040 wire can be used
on this welder. You can also use 4" spools of wire when using the optional Quick Draw Spool Gun
#44453.
NOTE: - Burn through can occur if you attempt to weld mild or stainless steel thinner than 24 gauge.
- Remove all rusted wire from your wire spool. If the whole spool is rusty, discard it.
4.2 Installing the wire
Electrical Shock

Electric shock can kill! Always turn the POWER switch OFF and unplug the power cord
from the AC power source before installing wire.
NOTE:
- Before installing, make sure that you have removed any old wire from the torch assembly. This will
help to prevent the possibility of the wire jamming inside the gun liner.
- Be very careful when removing the welding nozzle. The contact tip on this welder is live whenever
the torch trigger is pulled. Make certain POWER is turned OFF.
4.2.1 Remove the nozzle and contact tip from the end of the torch assembly.
4.2.2 Make sure the proper groove on the drive roller is in place for the wire installed. If not,
change the drive roller as described in Section 3.
