5. Loosen the socket head cap screw that holds the
connector bar against the gun adapter.
Important: Do not attempt to completely
remove the socket head cap screw.
6. Remove the outer wire guide, and push the gun
adapter out of the wire drive. Because of the preci-
sion fit, light tapping may be required to remove
the gun adapter.
7. Disconnect the shielding gas hose from the gun
adapter, if required.
8. Connect the shielding gas hose to the new gun
adapter, if required.
9. Rotate the gun adapter until the hand screw hole
aligns with the hand screw hole in the feed plate.
Slide the gun adapter into the wire drive and verify
the hand screw holes are aligned.
10. Tighten the socket head cap screw.
11. Insert the welding gun into the gun adapter and
tighten the hand screw.

MAKING A WELD

1. Check that the electrode polarity is correct for the
process being used, then turn the power switch ON.
2. Set desired arc voltage tap and wire speed for the
particular electrode wire, material type and thick-
ness, and gas (for MIG and Outershield
used. Use the Application Chart on the door inside
the wire compartment as a quick reference for
some common welding procedures.
NOTE: Application Chart can also be found in
Section F of this Instruction Manual.

3. Press the trigger to feed the wire electrode through
the gun and cable. For solid wire cut the electrode
within approximately 3/8" (10 mm) of the end of the
contact tip [3/4" (20 mm) for Outershield
4. When welding with gas, turn on the gas supply and
set the required flow rate (typically 30-40 CFH; 14-
19 liters/min).
5. Connect work cable to metal to be welded. Work
clamp must make good electrical contact to the
work. The work must also be grounded as stated in
"Arc Welding Safety Precautions".
-----------------------------------------------------------------------
6. Position electrode over joint. End of electrode may
be lightly touching the work.
7. Lower welding helmet, close gun trigger, and
begin welding. Hold the gun so that the contact tip
®
) being
to work distance is about 3/8" (10 mm) [3/4" (20
mm) for Outershield
8. To stop welding, release the gun trigger and then
pull the gun away from the work after the arc goes
out.
