4) Tighten the cover as much as possible by hand.
DO NOT hammer on the spinner nut arms.
5) Cut and remove only the tie wire holding the free
end of the coil. Insert the free end into one of the
holes in the cover and secure it by bending it back.
Cut and remove the remaining tie wires.
Always be sure the free end of the coil is securely
held while the tie wires are being cut and until the wire
is feeding through the drive rolls. Failure to do this will
result in “backlashing” of the coil, which may tangle
the wire. A tangled coil will not feed so it must either
be untangled or discarded.

6) Replace the reel on the wire feeder. Grasp the
shaft knob, pull it out and swing it across the reel
hub, locking the reel in place.
Feeding Electrode
1) Turn the reel until the free end of the electrode is
accessible. While tightly holding the electrode, cut
off the bent end.
2) Straighten the first 6” (150mm) and cut off the first
1” (25mm). Insert the free end through the incoming
guide tube. Press the Cold Inch key or the gun trigger
and push the electrode into the drive roll. Feed the
electrode through the gun. (If the electrode is not
properly straightened, it may not feed or may not go
into the outgoing guide tube causing a “birdnest”.)
When feeding with the gun trigger, the electrode and
drive mechanism are always “HOT” to work and
ground and could remain “HOT” several seconds after
the gun trigger is released.

Wire Reel Loading - 50-60lb (22.7-27.2kg)
Coils (K299 Wire Reel Mounting Kit)
Adjustable Wire Reel Brake
The mount for standard 50-60 lb (22.7-27.2 kg) elec-
trode coils includes a two-position brake assembly.
Generally the brake should be at the inner position
(nearest to the wire reel shaft) for wire feed speeds
below 400 in/min. (10m/m). It should be at the outer
position for the faster wire speeds often used when
feeding small diameter electrode.
To adjust the brake position, remove the wire reel.
Pull the cotter pin that holds the brake shoe to the
arm, move the shoe and replace the cotter pin. Do
not bend the cotter pin - it is held in place by a friction
fit.
To Mount a 50-60lb (22.7-27.2kg) Coil:
1) To remove the wire reel from its shaft, grasp the
spring loaded knob and pull it out. This straightens
the knob so it seats into the shaft when released.
Remove the reel.
2) Lay the reel flat on the floor, loosen the spinner nut
and remove the cover plate.
3) Before cutting the tie wires, place the coil of elec-
trode on the reel so it unwinds as the reel rotates
clockwise.
a) Be sure the coil is placed so the spring loaded
arms will not interfere with the later removal of
the coil tie wires (see illustration below).
b) When loading .030-.045” (0.8-1.2mm) elec-
trode, be certain the coil is placed on the reel so
the spring loaded arms are at the center of the
slots in the cardboard coil liner. This provides
the positive compression of the coil sides need-
ed for trouble-free wire feeding (see illustration).
c) Put the cover plate on the reel so that the four
arms of the cover straddle and are in line with
the spring loaded arm of the reel proper.
