8-2 Changing AccuLock™ S Consumables
A. Removal
1. Loosen the set screw in the power pin cap and remove the cap
from the rear of the gun.
2. Remove the nozzle. Loosen and remove the diffuser.
3. 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. Place the power pin cap over the liner extending from the rear
of the gun, and thread the cap onto the power pin.
6. Tighten cap snug against the power pin shoulder with welding
pliers.
7. Lay the gun straight, making sure there are no twists in the
cable. Holding a hex wrench by its shank, tighten the set screw
“finger tight” against the liner.
8. Hold the hex wrench by the handle and tighten the set screw an
additional half turn (180°) to fully secure the liner.
9. Trim the exposed portion of the liner flush with power pin cap.
10. Insert a piece of welding wire into the liner to check for burrs or
obstructions. If needed, loosen screw slightly until wire slides
freely.
