CHANGING LINER

NOTICE: The variation in cable lengths pre-

vents the interchangeability of liners. Once

a liner has been cut for a particular gun, it

should not be installed in another gun

unless it can meet the liner cutoff length

requirement. Refer to Figure D.2.

1. Remove the gas nozzle from the gun by

unscrewing counter-clockwise.

2. Remove the existing contact tip from the

gun by unscrewing counter-clockwise.

3. Remove the gas diffuser from the gun

tube by unscrewing counter-clockwise.

4. Lay the gun and cable out straight on a

flat surface. Loosen the set screw locat-

ed in the brass connector at the wire

feeder end of the cable. Pull the liner out

of the cable.

5. Insert a new untrimmed liner into the

connector end of the cable. Be sure the

liner bushing is stenciled appropriately

for the wire size being used.

6. Fully seat the liner bushing into the con-

nector. Tighten the set screw on the

brass cable connector. At this time, the

gas diffuser should not be installed onto

the end of the gun tube.

7. With the gas nozzle and diffuser

removed from the gun tube, be sure the

cable is straight, and then trim the liner

to the length shown in the Figure D.2.

Remove any burrs from the end of the

liner.

8. Screw the gas diffuser onto the end of

the gun tube and securely tighten.

9. Replace the contact tip and nozzle.
