INSTALLING 4-INCH SPOOL (SEE FIGURE FOR PART IDENTIFICATION):
1.
Open the access panel.
2.
Unscrew and remove the wire spool retention cap used for 8-inch spools (A) and store it someplace safe.
3.
Remove the spindle adapter for 8-inch spools (B) and store it someplace safe.
4.
Remove the nut (C), spring (D), and washers (E).
5.
Remove the outer wrapping from the included 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.
6.
Place the spool on the WIRE SPOOL SPINDLE (13) in such a manner that when the wire comes off the spool,
it will look like the illustration above. The wire should unspool from the bottom, and the spool will rotate in a
counter-clockwise fashion.
7.
Place the washer, wire spool locking bushing, spring, and nut back in place.
8.
Proceed to "FEEDING WIRE THROUGH THE MIG GUN" instructions below.
INSTALLING 8-INCH SPOOL (SEE FIGURE FOR PART IDENTIFICATION):
1.
Open the access panel.
2.
Unscrew and remove the wire spool retention cap (A).
a. NOTE: If the wire spool retention cap and the spindle adapter for 8-inch spools (B) are not present (machine
was last used with a 4-inch spool) put the spindle adapter for 8-inch spools back in place.
3.
Make sure all of the components used for a 4-inch spool are still in place. They are necessary for 8-inch spools
as well (nut (C), spring (D), and washers (E)).
4.
Remove the outer wrapping from 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.
5.
Place the spool on the spindle adapter for 8-inch spools in such a manner that when the wire comes off the
spool, it will look like the illustration above. The wire should unspool from the bottom, and the spool will rotate in
a counter-clockwise fashion.
a. NOTE: Be sure the alignment pin near the base of the spindle adapter for 8-inch spools is inserted in the
corresponding hole on the spool.
6.
Thread the wire spool retention cap back in place.
FEEDING WIRE THROUGH THE MIG GUN:
1.
Unhook the wire and hold the wire end and the spool in one hand. With the other hand tighten the nut (C) just
enough so that when the spool is released it does not spin freely and uncoil the wire. Tightening the nut too
much may cause inconsistent wire feeding. Leaving it too loose will allow the wire to uncoil freely from the spool,
leaving a mess of wire in the cabinet.
2.
While holding the wire in place, use a wire cutter to cut the bent end of the wire so that only a straight end
remains.
3.
Continue to hold the wire end in one hand and release the drive roll pressure arm (I) by pulling the pressure arm
adjustment knob (G) toward you. Hold the drive roll pressure arm up off of the drive roller and insert the leading
end of the wire into the inlet guide tube (H). Push the wire across the drive roller (J) and into the gun assembly
approximately six inches.
4.
Line the wire up in the outside groove of the drive roller and allow the drive pressure arm to drop onto the
drive roller. Pull the pressure arm adjustment knob back over the pressure arm and tighten (turn clockwise) the
pressure adjusting knob until the pressure roller is applying enough force on the wire to prevent it from slipping
out of the drive assembly. NOTE: Too much pressure will cause wire to feeding problems and may burn out the
wire feed motor.
5.
Let go of the wire.
6.
Remove the nozzle (K) and contact tip (L) from the end of the gun assembly (M).
7.
Plug the welder's INPUT POWER CABLE into the AC power source. Adjust the settings on the front panel per the
setup chart on the inside panel door of the welding machine according to the size of the wire and workpiece.
8.
Pull the trigger on the MIG gun to feed the wire through the gun assembly. Check if the drive roll is slipping on
the wire and increase pressure on the pressure arm adjustment knob if necessary.
9.
When at least an inch of wire sticks out past the end of the gun, release the trigger.
10.
Slide the contact tip (L) over the wire protruding from the end of the gun (M). Screw the contact tip into the end
of the gun and hand tighten securely.
11.
Install the nozzle (K) on the gun assembly.
