Drive and Idler Rolls

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 Optional kits).

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.

----------- IMPORTANT -----------

NOTE: Over-tightening of the drive rolls will cause excessive knurling and/or deformation of the wire. When the complete system is setup properly, feeding wire out of the end of the torch and letting fall on the ground should form a large uniform circle. If it forms a spiral or spring then there is too much tension in the system, please refer to the Cabinet Owners Manual for adjustment to the tension setting.

INCORRECT DRIVE ROLL TENSION IS THE NUMBER ONE

CAUSE OF POOR WIRE FEED PERFORMANCE

DRIVE ROLL INSTALLATION AND REMOVAL

Note:

Neither of the handles needs to be removed to access the Drive or Idler Rolls.

1.Using a 5/32” hex wrench, loosen the Idler Roll tension screw. This will relieve the pressure against the drive roll.

2.Align the Drive Roll Removal Tool (P/N 931-0100) over the ﬂ ats of the drive roll. Hold the torch 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 torch.

4.Install a new drive roll on the left-hand threaded shaft. The drive roll will self-tighten when it is feeding wire.

IDLER ROLL INSTALLATION AND REMOVAL

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.
