Barrel
The Millermatic Compatible™ Python ® comes standard with a 60˚ curved
barrel. The barrel assembly locks to the Python ® body using the patented EZ
Lock™ system.
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, push the barrel assembly into the gun body
until it stops. 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.
Barrel Liner
The standard Teflon liner in the Millermatic Compatible™ Python ® barrel is
designed for aluminum and other soft wire. A Steel liner is available for steel,
cored and other hard wires.
NOTE: Contact the factory for more barrel options.
