A. Removal
1. Remove threaded nozzles by turning in a counterclockwise
direction. Slip-on nozzles can be removed by pulling straight
away from the gun.
2. Cut wire end with sharp side cutters to remove the ball,
allowing for the tip to slide over the wire.
3. Unthread the contact tip from the gas diffuser by twisting in a
counterclockwise rotation. You may need pliers, or welding
pliers, to break the connection loose.
4. Remove the gas diffuser from the neck by using an open-end
wrench on the flats of the diffuser to turn counterclockwise.
5. Remove the power pin cap of the back of the gun, and then
pull the liner out of the gun from the neck.
B. Installation
1. Insert the heat-shrink end of the liner in through the neck, and
push the liner all the way through the gun using short strokes
to avoid kinking until the brass end of the liner stops on the
neck face.
2. Reinstall gas diffuser by threading in a clockwise rotation.
Tighten with a wrench and torque to 144 in-lbs (12 ft-lbs).
3. Reinstall the contact tip by threading into the gas diffuser by
hand and tighten with non-marring pliers. Torque to 30 in-lbs
(3.5 Nm). NOTE:AccuLock tip tool part # T-ALTOOL is
recommended.
4. Reinstall the thread-on nozzle by turning clockwise onto the
gas diffuser and hand tighten. To reinstall a slip-on nozzle,
press the nozzle toward the gas diffuser by hand until you feel
a positive stop.
5. Trim the liner:
a. Lay the gun straight, making sure there are no twists in
the cable, and tighten the power pin cap by placing a
wrench on the power pin and a second wrench on the
power pin cap. Torque to 120 in-lbs (10 ft-lbs).
b. Cut liner portion sticking out of the power pin to the
desired length stick-out. NOTE: Cutting flush to the power
pin is recommended in most applications.
IMPORTANT: Failing to tighten to the minimum spec may result in
liner slippage and porosity. Extreme over-tightening may cause
damage to the liner and/or the power pin cap.
