the end of the gun assembly.
2. Make sure the proper groove on the drive
roller is in place for the wire being installed.
If the proper groove is not in place, change
the drive roller as described above.
3. Unwrap the spool of wire and then find the
leading end of the wire (it goes through a
hole in the outer edge of the spool and is
bent over the spool edge to prevent the
wire from unspooling), BUT DO NOT
UNHOOK IT YET.
4. Place the spool on the spindle in such a
manner that when the wire comes off the
spool, it will look like the top illustration in
Figure 6. The welding wire should always
come off the top of the spool into the drive
mechanism.

5. If you are installing a four-inch spool of
wire, install the drive brake hardware on
the top of the spool of wire according to
figure 7A. If you are installing an eight-inch
spool, install the spindle adapter and drive
brake hardware as shown in Figure 7B.
The purpose of the drive brake is to cause
the spool of wire to stop turning at nearly
the same moment that wire feeding stops.
6. Once the drive brake hardware is installed,
set the spool tension. With one hand, turn
the wire spool and continue turning it while
adjusting the tension on the spool. With
your free hand, tighten (turn clockwise) the
knob that holds the spool in place. Stop
tightening when drag is felt on the wire
spool that you are turning, then stop hand-
turning the wire spool.
Note: If TOO MUCH tension is applied to the
wire spool, the wire will slip on the drive roller or
will not be able to feed at all. If TOO LITTLE
tension is applied, the spool of wire will want to
unspool itself. Readjust the drive brake tension
as necessary to correct for either problem.
7. After checking to make sure that your
welder is disconnected from the ac power
source, free the leading end of the wire
from the spool, but do not let go of it until
told to do so, or the wire will unspool itself.
8. Use a wire cutter, cut the bent end off the
leading end of the wire so that only a
straight leading end remains.
9. Loosen the tension adjusting screw holding
the drive tension arm in place and lift the
tension arm up off the drive roller.
10. Insert the leading end of the wire into the
inlet guide tube. Then push it across the
drive roller and into the gun assembly
about six inches.
CAUTION
Make certain that the welding wire is actually is
going into the gun liner. Be very sure it has not
somehow been accidentally been routed
alongside the liner or even in some other
direction. If this should happen, the wire could
feed inside the cable casing or take a right
angle and follow the wires and gas hose inside
the welder. It could also feed back on itself
jamming up the mechanism.
11. Line the wire up in the inside groove of the
drive roller, then allow the drive tension
arm to drop onto the drive roller.
12. Flip the quick release drive tensioner back
up into position on the drive tensioner arm.
13. Tighten (turn clockwise) the drive tension
adjusting screw until the tension roller is
applying enough force on the wire to pre-
vent it from slipping out of the drive assem-
