3. Refer to the diagram below: At the adaptor block end of the torch cable,
slide the brass collet and O-ring over the liner until they are located in the
recess in the adaptor block; replace the liner retaining nut. DO NOT CUT
THE LINER YET!
4. If the wire feed unit was previously set up for steel wire, it may be necessary
to take a pair of long-nosed pliers and remove the steel inlet guide from the
central adaptor installed in the front face of the wire feed unit.
5. With the plastic liner still protruding from the adaptor plug, feed the liner
through the inlet of the central adaptor until the adaptor plug on the torch is
butted against the central adaptor. Fasten into position with the plastic adap-
tor nut. Lift the feed rollers of the wire feeder to enable the excess liner to
pass through. Cut the liner, using a sharp knife, so that it butts up to the feed
rollers, thereby supplying support to the soft wire immediately after it exits
the drive rolls. If this is done correctly, “bird-nesting” in the event of a wire
jam will be prevented.
6. Remove the welding gun from the machine and ensure that the brass guide
tube is 3mm shorter than the protruding plastic liner (if not, cut accordingly).
Slide the guide tube over the liner and feed the liner (with the guide tube
fi tted) into the inlet in the central adaptor; continue to feed through until the
adaptor plug is butted against the central adaptor, then tighten the plastic
adaptor nut.
Note: Plastic liners with a diameter of 4.7mm do not require a guide tube.
(See diagram below for correct location of parts.)
7. Reduce the wire hub tension by backing off the nut in the center of the hub
until the friction is only enough to stop the wire spool from spinning freely.
8. After
confi rming that the feed rolls are the correct size and type for the wire
being used, and that the wire is fed into the liner correctly, back off the wire
feed roll pressure until the feed rolls no longer feed the wire, then retighten
slightly. Be cautious, as too much pressure will deform soft wires such as
aluminum and cause the wire to jam in the contact tip.

1. Thread the connector plug into the rear of the torch (the connector plug may differ
from the one shown).
2. Tighten down the set screw with the Allen key provided.
3. Connect the appropriate end of the trigger lead jumper supplied in the kit to the con-
nector exiting the torch (the trigger lead may also differ from the one shown).
4. Install the gun liner supplied with the torch as per the liner installation instructions on
pages 4-5.
5. The torch is now ready to install into the feeder. Finally, hook up the trigger connector
on the feeder side.
