HOW TO THREAD WELDING WIRE THROUGH THE WIRE FEEDER
1. Unlock the tension bar (1) on the wire tensioner and lift up the rocker arm (2). Insure that
the wire drive wheel is appropriate to the welding wire size, see above describing the installation
to wire feed roller installation.
2. Pull out the welding wire (3) from the welding wire spool carefully.
NOTE: Do not let go of the wire prior to step 5 or the entire spool will unravel and be
useless.
3. Cut off the small piece of the curved segment at the front of welding wire and straighten the
welding wire approximately 3.0” long.
4. Thread the welding wire through the guide pipe (4) and over the wire feed roller (5) and into
the torch hole (6).
5. Reattach the rocker arm (2) and reset the presser bar (1) of the wire feeder (now the welding
wire can be fed smoothly).
6. Remove the contact tip and nozzle from the Mig torch.
7. Turn on the machine and set the wire speed about ½ on the scale.
8. With the gun pointed away from you and others, depress the trigger to begin feeding wire.
NOTE: Watch the drive roller to see if any slipping is occurring between the roller and the wire-
if so turn the machine off and tighten the tension wing nut ¼ turn and test again.
9. You do not want too much tension on the tension roller as it will tend to deform the wire.
Just enough to feed the wire without slipping
10. Once the wire has emerged from the tip of the gun, turn the machine OFF and replace the tip
and nozzle.
