Optional insulated V-groove drive rolls are also available for aluminum wire if 

desired (see optional kits).
Drive roll tension is accomplished with a unique spring-loaded pressure 

screw.  The Millermatic Compatible™ Python 

®

 comes from the factory with 

the pressure adjustment screw preset.

1.  Pull  the cam lever away from the 

idler roll.  This will relieve the pressure 

against the drive roll (as shown in Figure 

1).

2.  Align  the drive roll removal tool over the 

flats of the drive roll (as shown in Figure 

2).  Hold the gun with one hand or on a 

table top, with the other hand give the 

removal tool a quick snap-turn in the 

CLOCKWISE DIRECTION.

3.  Once the drive roll is loose, continue to 

spin drive roll in the clockwise direction 

to remove the drive roll from the gun.

4.  Install a new drive roll on the left-hand 

threaded shaft.  The drive roll will self-

tighten when it is feeding wire.

(Reference Figure 3)
1.  Using a slot type screwdriver, loosen idler screw, taking care not to lose 

lock washer under idler roll.

2.  Insert new idler roll and lock washer onto screw, insuring that idler groove 

is toward top and lock washer is beneath.

3.  Tighten screw until tight.
