----------- IMPORTANT -----------
NOTE:
Over-tightening of the drive rolls will cause excessive knurling and/or deformation
of the wire. When the complete system is set-up properly, wire will feed out of the
end of the torch and fall on the ground forming a 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 detailed there.
THIS IS THE NUMBER ONE CAUSE OF POOR WIRE FEED PERFORMANCE
---------------------------------------------
Drive Roll Installation/Removal
Please Note : Drive rolls have a LEFT HAND thread.
Remove the drive roll with small nose pliers by turning the drive roll clockwise.
Install new drive roll on motor shaft using left hand thread. Drive roll will
self-tighten when 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.
3. Tighten.
