Adjust the drive roller according to the follow-
ing steps:
1. Open the Wire Drive cover on the Spool
Gun.
2. Remove the drive tension by loosening
the tension adjusting screw and lifting the
Drive Tension Adjustor up, 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 clockwise. 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
spool gun.
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.
Note: The drive roller has two wire size
grooves built into it. When installing the drive
roller, the number stamped on the drive roller
for the wire size you are using should be fac-
ing you. Use only the proper size drive roller
when using your welder.
Table 4 indicates which drive roller groove
should be used with each wire diameter size.
4. Find the side of the drive roller that is
stamped with the same wire diameter as
that of the wire being installed (see
Figure 10). Push the drive roller onto the
drive roller shaft, with the side stamped
with the desired wire diameter facing you.
5. Reinstall the Drive Roller Cap and lock in
place by turning it clockwise.
6. Close the Wire Drive cover on the Spool
Gun.
