CAUTION

Excessive pressure at the start may cause the dirt to form a plug.

Flex the cable over its entire length and again blow out the cable. Repeat this procedure until no further dirt comes out. If this has been done and feed prob- lems are experienced, try liner replacement, and refer to trouble shooting section on rough wire feeding.

LINER REMOVAL AND REPLACEMENT

(SEE FIGURE D.1)

LINER REMOVAL, INSTALLATION AND TRIMMING INSTRUCTIONS FOR MAGNUM 300

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.

2.Remove the gas diffuser from the gun tube. If gas diffuser contains a small set screw, loosen the set screw.

3.Lay gun and cable out straight on a flat surface. Loosen set screw of the connector on the back end of the gun.

4.Insert the untrimmed Liner into the back end of the gun.

5.Seat Liner bushing into back of gun. Secure Liner by tightening set screw. Do not install the gas dif- fuser at this time.

6.Lay the cable straight and trim Liner to 9/16”. Remove burrs.

7.Secure the gas diffuser into the tube.

8.Tighten the set screw against the Liner.

CAUTION

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