Liner trim length

NOTICE: The variation in cable lengths prevents 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 gun and cable assembly from machine.

2.Remove the gas nozzle from the gun by unscrewing counter-clockwise.

3.Remove the existing contact tip from the gun by unscrewing counter-clockwise.

4.Remove the gas diffuser from the gun tube by unscrewing counter-clockwise.

5.Lay the gun and cable out straight on a flat sur- face. Loosen the set screw located in the brass connector at the wire feeder end of the cable. Pull the liner out of the cable.

6.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.

7.Fully seat the liner bushing into the connector. Tighten the set screw on the brass cable con- nector. At this time, the gas diffuser should not be installed onto the end of the gun tube.

8.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.

9.Screw the gas diffuser onto the end of the gun tube and securely tighten.

10.Replace the contact tip and nozzle.
