GUN AND CABLE INSTALLATION

AMagnum 300 gun and 15Ft.(4.6m) cable (12Ft.(3.7m) for Codes 11000 and below) are provid- ed with the POWER MIG 300. A Magnum cable liner for .035-.045" (0.9-1.2 mm) electrode and contact tips for .035” (0.9mm) and .045” (1.2mm) are included for 15Ft..

WARNING

Turn the welder power switch off before installing gun and cable.

LINER INSTALLATION AND TRIMMING INSTRUCTION (SEE FIGURE A.3)

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.

GUN & CABLE ASSEMBLY INSTALLED INTO THE POWER MIG

1.Unscrew knurled screw on the drive unit front end (inside wire feed compartment) until tip of screw no longer protrudes into gun opening as seen from front of machine.

2.Insert the male end of gun cable into the female casting through opening in front panel. Make sure connector is fully inserted and tighten knurled screw.

3.Connect the gun trigger connector from the gun and cable to the mating receptacle inside the com- partment located above the gun connection made in step 2 above. Make sure that the key ways are aligned, insert and tighten retaining ring.

SHIELDING GAS

(For Gas Metal Arc Welding Processes)

Customer must provide cylinder of appropriate type shielding gas for the process being used.

A gas flow regulator, for CO2 or Argon blend gas, and an inlet gas hose are factory provided with the POWER MIG 300.

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.

WARNING

CYLINDER may explode if damaged.

• Gas under pressure is explosive. Always keep gas cylinders in an upright position and always keep chained to undercarriage or stationary support. See American National Standard Z-49.1, “Safety in Welding and Cutting” published by the American Welding Society.

Install shielding gas supply as follows:

1.Set gas cylinder on rear platform of POWER MIG 300. Hook chain in place to secure cylinder to rear of welder.

2.Remove the cylinder cap. Inspect the cylinder valves and regulator for damaged threads, dirt, dust, oil or grease. Remove dust and dirt with a clean cloth.
