5. Choose a drive roller based on the thickness of the welding wire. Twist the retainer knob
and flip the cap up (Fig. 7). Place the roller onto the spindle with the correct wire size on
top. Flip the cap down and twist to lock in place.
5.1 Flux-Core – Install a knurled drive roller. Apply a light amount of pressure to the drive roller.
Too much pressure will crush the cored wire.
6. Loosen the tension knob and swing it up and out of the way (Fig. 8). Swing the pressure
roller arm out of the way as well.
7. Snip the wire carefully, be sure to hold the wire to prevent the spool uncoiling. Carefully
feed the wire into the inlet guide tube of the wire feed unit (Fig. 8).
8. Feed the wire through the drive roller and into the outlet guide tube of the wire feeder.
9. Swing the pressure arm into place against the roller and lock it into place with the tension
arm. Tighten the knob to apply a medium amount of pressure (Fig. 9).
10. Remove the gas nozzle and contact tip from the torch neck (Fig. 10)
11. Press and hold the welding torch trigger to feed the wire through to the torch neck. Release
the trigger when the wire exits the torch neck.
12. Fit the correct sized contact tip and feed the wire through it, screw the contact tip into the
tip holder of the torch head. Clip the wire close to the tip unless testing the drive tension.
13. Fit the gas nozzle to the torch head (Fig. 10).
14. A simple check for the correct drive tension is
to bend the end of the wire over hold it about
4 in. from your hand and let it run into your
hand, it should coil round in your hand
without stopping and slipping at the drive
rollers, increase the tension if it slips (Fig. 11).
15. Insufficient tension on the wire spool can
allow it to spin after the wire feeding
mechanism stops, forcing loops of wire off
the spool to become tangled. Increase the
pressure on the tension spring inside the
spool holder assembly by adjusting the tension screw if this happens (Fig. 6).
