Barrel Removal and Installation

CAUTION: Power-off the coolant pump before removing or loosening liquid-cooled cups and barrels.

To remove the barrel assembly, loosen the patented EZ Lock™ taper lock nut until it is clear of the threads. Pull barrel out of the gun body.

To replace a barrel assembly, push the barrel assembly into the gun body until it clicks to a stop. To assure proper seating of the barrel, open the drive/ idler roll door in the top of the handle. The rear face of the barrel should now be flush with the gun body. Take care not to damage the o-rings when inserting into the body. Tighten taper lock nut assembly firmly so that barrel cannot rotate while welding.

Barrel Rotation

To rotate a barrel assembly, loosen the patented EZ Lock™ taper lock nut assembly no more than 1 turn. Rotate barrel to the position of your choice and re-tighten taper lock nut assembly firmly so that the barrel cannot rotate.

CAUTION: Do not attempt to weld without the barrel being tightly secured in the gun body, or damage to the barrel or body may result.

Maintenance

Disconnect Power

Before Maintaining.

Periodic Maintenance

Your liquid cooled Millermatic Compatible™ Python® is designed to provide years of reliable service. Maintenance of the gun will normally consist of a general cleaning of the wire guide system, including barrels, drive rolls, and conduits at regular intervals.

Remove spatter build-up from inside of nozzles with a hardwood stick.

The only parts that are subject to normal wear are the conduit, contact tips, nozzles, barrel liners, wire guides, drive and idler rolls. A supply of these parts should be maintained on hand.

The number of units in operation and the importance of minimal down time will determine to what extent spare parts should be stocked on hand. See the recommended spare parts list for the most commonly replaced parts.

It is recommended that you blow out your conduit each time you install a new spool of wire.

If repairs do become necessary, qualified shop maintenance personnel can easily replace any part.
