Barrel Removal and Installation
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, open the drive and idler roll door and seat the
barrel assembly until the inlet guide is almost touching the drive and idler roll
and the rear face of the barrel is flush with the aluminum body block. Take
care not to damage the “O” rings when inserting into the body. Tighten taper
lock nut assembly firmly so that barrel cannot rotate.
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 retighten taper lock nut assembly firmly so that the barrel cannot rotate.
WARNING: Do not attempt to weld without the barrel being tightly
secured in the gun body, or damage to the barrel or body may result.
Section D Maintenance
Periodic Maintenance
Your Cobramatic ® System 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 on the Cobramatic
® system that are subject to normal wear
are the conduit, contact tips, gas cups, front body 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.
If repairs do become necessary, qualified shop maintenance personnel can
easily replace any part.
