ALIGN AND SET THE DRIVE ROLLER
Before installing any welding wire into the
unit, the proper sized groove must be placed
into position on the wire drive mechanism.
Adjust the drive roller according to the
following steps:
1. Open the door to the welder drive com-
partment.
2. Remove the drive tension by loosening
the tension adjusting knob and lifting the
Drive Tension Adjustor away from the
Drive Tension Arm. Pull the drive tension
arm away from the drive roller.
3. If there is wire already installed in the
welder, roll it back onto the wire spool by
hand-turning the spool counterclockwise.
Be careful not to allow the wire to come
out of the rear end of the inlet guide tube
without holding onto it or it will unspool
itself. Put the end of the wire into the hole
on the outside edge of the wire spool and
bend it over to hold the wire in place.
Remove the spool of wire from the drive
compartment of the welder.
4. Rotate the Drive Roller Cap counterclock-
wise and remove it from the Drive Roller.
5. Pull the Drive Roller off of the Drive
Roller Shaft.
