7.Screw the gas diffuser onto the end of the gun tube and securely tighten. Be sure the gas diffuser is correct for the liner being used. (See table and dif- fuser stencil.)

8.Tighten the set screw in the side of the gas diffuser against the cable liner using a 5/64" (2.0 mm) Allen wrench.

NOTE: The variation in cable lengths prevents the interchangeability of liners between guns. 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. Liners are shipped with the jacket of the liner extended the proper amount.

1.Remove the gas nozzle and nozzle insulator, if used, to locate the set screw in the gas diffuser which is used to hold the old liner in place. Loosen the set screw with a 5/64" (2.0 mm) Allen wrench.

2.Remove the gas diffuser from the gun tube.

3.Lay the gun and cable out straight on a flat surface. Loosen the set screw located in the brass connec- tor at the feeder end of the cable and pull the liner out of the cable.

4.Insert a new untrimmed liner into the connector end of the cable. Be sure the liner bushing is sten- cilled appropriately for the wire size bing used.

5.Fully seat the liner bushing into the connector. tighten the set screw on the brass cable connector. the gas diffuser, at this time, should not be installed onto the end of the gun tube.

6.With the gas diffuser still removed from the gun tube, be sure the cable is straight, and then trim the liner to the length shown in Figure D.1. Remove any burrs from the end of the liner.

CAUTION

This screw should only be gently tightened. Overtightening will split or collapse the liner and cause poor wire feeding.
