4. Open the Wire Spool Casing, located at
the rear of the Spool Gun, by turning the
retaining knob counterclockwise.
Figure 11. Spool Cover
5. Unwrap the spool of wire and then find
the 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).
6. 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.
7. Loosen the tension adjusting knob
holding the drive tension arm in place and
lift the tension arm up off the drive roller.
8. Using a pair of pliers, cut off the bent por-
tion at the end of the wire so that you are
left with a straight section of wire.
9. Unroll about 10 inches of welding wire
from the wire spool.
10. Insert the leading end of the wire into the
inlet guide tube (located in the Wire
Spool Casing). Then push it across the
drive roller and into the gun assembly
about six inches.
11. Line the wire up in the top groove of the
drive roller, then push the drive tension
arm against the drive roller.
12. Flip the quick release drive tensioner
back into position on the drive tensioner
arm.
13. Tighten (turn clockwise) the drive tension
adjusting knob until the tension roller is apply-
ing enough force on the wire to prevent it
from slipping out of the drive assembly.
14. Let go of the wire.
15. 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 12. The welding wire should
always come off the top of the spool into
the drive mechanism.

Technical Note: 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.
