7. Replace the drive and idle rolls and inside wire
guide with a set marked for the new wire size.
NOTE: Be sure that the gun liner and contact tip are
also sized to match the selected wire size.
8. Manually feed the wire from the wire reel, over the
drive roll groove and through the wire guide and
then into the brass bushing of the gun and cable
assembly.
9. Replace the outside wire guide retaining plate by
tightening the two large knurled screws.

WIRE REEL LOADING -
READI-REELS, SPOOLS, OR COILS
To Mount a 30 lb (14 kg) Readi-Reel
Package (Using the Molded Plastic K363-P
Readi-Reel Adapter:)
1. Open the wire drive compartment door.
2. Depress the release bar on the retaining collar
and remove it from the spindle. See Figure B.2.
3. Place the optional adapter on the spindle.
4. Re-install the retaining collar. Make sure that the
release bar “pops up” and that the collar retainers
fully engage the retaining ring groove on the
spindle.
5. Rotate the spindle and adapter so the retaining
spring is at the 12 o'clock position.
6. Position the Readi-Reel so that it will rotate in a
direction when feeding so as to be de-reeled from
top of the coil.
7. Set one of the Readi-Reel inside cage wires on
the slot in the retaining spring tab.
FIGURE B.2 — READI-REEL INSTALLATION.
8. Lower the Readi-Reel to depress the retaining
spring and align the other inside cage wires with
the grooves in the molded adapter.
9. Slide cage all the way onto the adapter until the
retaining spring “pops up” fully.
Check to be sure the retaining spring has fully returned
to the locking position and has securely locked the
Readi-Reel cage in place. The retaining spring must
rest on the cage, not on the welding
electrode.
------------------------------------------------------------------------
10. To remove Readi-Reel from adapter, depress
retaining spring tab with thumb while pulling the
Readi-Reel cage from the molded adapter with
both hands. Do not remove adapter from spindle.
To Mount 10 to 44 lb (4.5-20 kg) Spools
(12 in./300 mm Diameter) or 14 lb
(6 kg) Innershield Coils:
(For 13-14 lb (6 kg) innershield coils, a K435 coil
adapter must be used).
1. Open the wire drive compartment door.
2. Depress the release bar on the retaining collar
and remove it from the spindle.
3. Place the spool on the spindle making certain the
spindle brake pin enters one of the holes in the
back side of the spool (Note: an arrow mark on the
spindle lines up with the brake holding pin to
assist in lining up a hole). Be certain the wire
comes off the reel in a direction that it can de-reel
from the top of the coil.
4. Re-install the retaining collar. Make sure that the
release bar “pops up” and that the collar retainers
fully engage the retaining ring groove on the
spindle.
