v. The welder can use either 4 inch or 8 inch spools. See Figure 5 for additional
reference. The wing nut controls the tension on the spool.

vi. Setting the wire spool tension. a) Turn the spool of wire with one hand. b)
Increase the spool tension by tightening (turn clockwise) the wing nut while
turning the spool. Turn the spool while tightening the wing nut until the spool
slows down and you feel a slight drag. Stop tightening the wing nut; you may
need to repeat these steps until proper spool tension is achieved.
vii. If TOO MUCH tension is applied to the wire spool, the wire will slip on the
drive roller or will not be able to feed at all. If TOO LITTLE tension is applied,
the spool of wire will want to unspool itself when the trigger is released.
Readjust the spool tension using the wing nut as necessary to correct for
either problem.
viii. With the welder disconnected from the power source, remove the leading end
of the wire from the spool. Hold on to it securely, so as not to allow
unspooling or tangling of the wire as it will result in tangled wire and feeding
problems.
ix. Cut off any bent portion of the wire using a wire cutter.
x. Loosen the tension adjusting knob holding the drive tension arm in place and
lift the tension arm up off the drive roller.
xi. Insert the wire into the inlet guide tube and feed it across the drive roller and
into the torch assembly about six inches.
⚠CAUTION
 Make certain that the welding wire is actually going into the torch liner. If not, the wire will jam up in
the mechanism.
xii. Line the wire up with the correct groove in the drive roller. Place the drive
tension arm back above the drive roller.
xiii. Place the drive tension adjustment arm back in place.
xiv. Tighten (turn clockwise) the drive tension adjusting knob until the tension
roller is applying enough force on the wire to prevent it from slipping in the
drive rollers. DO NOT OVER TIGHTEN.
xv. NOW YOU CAN LET GO OF THE WIRE.
