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.

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.
