MAINTENANCE
2. Remove liner assembly. (See Maintenance
Section)
3. Remove gun tube assembly. (See Maintenance

4. Remove wire drive assembly. (See Maintenance
Section)
5. Disconnect trigger. Use adjustable pliers to
remove cable strain relief from right handle half.
(See figure D.13)
FIGURE D.13
6. Pull damaged cable out of the right handle half.
The cable connector will fit through the strain relief
opening. Mark the new cable at a point 4.750 to
4.813 inches from the end of the cable connector.
(See figure D.14)

8. Install the new gun cable. Pass the cable connec-
tor through the opening in the right handle, seat
the strain relief in place, and then check to insure
the cable is not kinked between strain relief and
connector. Reassemble gun by reversing steps 2
through 5.
CORRECTING WIRE SHAvING ISSUES
1. If the inlet of the liner assembly is shaving the alu-
minum wire (the wire is usually peeled off in curled
chips) during feeding, the wire feed centerlines of
the wire drive and the liner itself may be mis-
aligned.
• This misalignment may occur whenever the gun
tube, wire drive, or welding cable assemblies are
replaced.
• A limited amount of adjustment is available at the
gun tube mounting to possibly eliminate the shav-
ing problem.
2. Visually check if wire is centered in the liner's inlet
opening. Feed wire through the spool gun and note
which side the shaving seems to occur.
3. Remove left side of handle. See Figure D.10 Gun
Tube Replacement. Slightly loosen gun tube's nut
as shown.
4. Slide the gun tube in the mounting plate's hole to
realign the wire and then retighten the nut as
shown. Reassemble the gun.
5. Repeat steps 2 thru 4 until shaving is eliminated. A
light accumulation of fine dust is also permissible
after feeding 1/4 of a spool during welding use.
