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 clock-
wise) 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
instructed 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. Flip down the screw holding the drive ten-
sion 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-
going into the gun liner. Be very sure it has not
somehow been accidentallyrouted 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-
bly.
14. Let go of the wire.
15. Connect the welder power cord to the ac
power source. Turn the welder ON by set-
ting the VOLTAGE switch to the voltage
(heat) setting recommended for the gauge
metal that is to be welded. Refer to the
label mounted on the cover, inside the
drive compartment, for recommended
voltage (heat) settings for your welding job.
The VOLTAGE selector controls the weld
heat. There are four voltage heat selections
(numbered 1 through 4) available on this
welder. Position 1 provides the lowest volt-
age (heat) and position 4 the highest volt-
age (heat).
16. Set the WIRE SPEED control to the middle
of the wire speed range.
17. Straighten the gun cable and pull the trig-
ger on the welding gun to feed the wire
through the gun assembly.
18. When at least an inch of wire sticks out past
the end of the gun, release the trigger.
19. Select a contact tip stamped with the same
diameter as the wire being used. If
stamped in metric see DESCRIPTION.
Note: Due to inherent variances in flux-cored
welding wire, it may be necessary to use a con-
tact tip one size larger than your flux core wire
if wire jams occur.
20. Slide the contact tip over the wire (protrud-
ing from the end of the gun). Thread the
contact tip into the end of the gun and
hand-tighten securely.
21. Install the nozzle on the gun assembly. For
best results, coat the inside of the nozzle
with anti-stick spray or gel.
22. Cut off the excess wire that extends past
the end of the nozzle.
