applied, the spool of wire will want to
unspool itself when the trigger is
released. Readjust the spool tension
using the wing nut as necessary to
correct for either problem.
4.2.7.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 it is
secure in the drive system or the wire
will unspool itself.
4.2.8. Using a wire cutter, cut the
bent end off the leading end of the
wire so that only a straight leading
end remains.
4.2.9. Loosen the tension adjusting
knob holding the drive tension arm in
place and lift the tension arm up off
the drive roller.
4.2.10. Insert the leading end of the
wire into the inlet guide tube. Then
push it across the drive roller and into
the MIG gun/torch assembly about six
inches.
• Make certain that the welding
wire is actually going into the torch
liner. If not, the wire will jam in the
mechanism.
4.2.11 Be sure the wire lines up in the
groove of the drive roller then place
the drive tension arm back in place
above the drive roller.
4.2.12 Position the quick release
drive tension back up into position
into the drive tension arm.
4.2.13 Tighten (turn clockwise) the
drive tension adjusting knob until the
tension roller is applying enough
force on the wire to prevent it from
slipping out of the drive assembly.
Do not over tighten.
4.2.14. NOW YOU CAN LET GO OF
THE WIRE.
4.2.15. Plug in and turn the welder
ON. Set the VOLTAGE switch to the
voltage (heat) setting recommended
for the gauge metal that is to be
welded. Refer to the set up chart on
the inside of the wire feed
compartment door.
4.2.16. Set the WIRE SPEED control
in the middle of the wire speed range.
8.17. Straighten the MIG gun cable,
pull the trigger on the welding torch to
feed the wire through the torch
assembly. When at least one inch of
the wire sticks out past the end of the
torch, release the trigger.
4.2.18 Turn the Power Switch to the
OFF position.
4.2.19 Select a contact tip stamped
with the same diameter as the wire
being used.
NOTE:
Due to inherent variances in flux-
cored welding wire, it may be
necessary to use a contact tip one
size larger than your flux core wire if
wire jams occur.
4.2.20. Slide the contact tip over the
wire (protruding from the end of the
gun). Thread the contact tip into the
end of the gun adaptor and tighten
securely.
4.2.21. Install the nozzle on the gun
assembly. To keep spatter from
sticking to inside of the nozzle use
anti-spatter spray or gel.
4.2.22 Cut off the excess wire that
extends more than ¼” past the end of
the nozzle.
4.2.23. Turn the welder ON
