16.6 DRIVE AND IDLER ROLLS
16.6.1 GENERAL
The Prince™XL torch comes standard with knurled drive rolls which will
handle wire diameters from .023 - 1/16 inch. Optional grooved drive rolls are
also available for feeding aluminum wire if desired (see page 7).
Drive roll tension is accomplished by means of a pressure adjusting allen
screw located on the left hand side of the torch. Proper tension is achieved
when wire does not slip if a small amount of pressure is added to the wire as
it exits the tip.
NOTE: Over-tightening of the drive rolls will cause excessive knurling and/or
deformation of the wire.
16.6.2 DRIVE ROLL INSTALLATION & REMOVAL
Rotate drive roll by jogging drive motor with trigger switch or with finger tips
until slots line up with door.
Hold the drive roll with 3/8" open-end wrench.
Insert a slot type screwdriver into the slot on motor shaft, and turn screwdriver
CCW (left hand thread).
Install new drive roll on motor shaft using left hand thread. Drive roll will self-
tighten when feeding wire.
16.6.3 IDLER ROLL INSTALLATION & REMOVAL
Using a slot type screwdriver, loosen idler screw, taking care not to lose lock
washer under idler roll.
Insert new idler roll and lock washer onto screw, insuring that idler groove is
