LOADING 50 AND 60 LB. COILS ON 1"
SPINDLE (K299 or K303 Wire Reel Stand)
ADJUSTABLE WIRE REEL BRAKE
The mount for standard 50 and 60 pound electrode
coils includes a two position brake assembly.
Generally the brake should be a the inner position
(nearest to the wire reel shaft) for wire feed speeds
below 400 in/min. 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.
LOADING A 50 OR 60 LB. COIL
1. To remove the wire reel from its shaft, grasp the
spring loaded knob and pull it out. This straightens
the knob so that 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 that it unwinds as the reel
rotates clockwise.
a) Be sure the coil is placed so that the spring loaded
arms will not interfere with the later removal of the
coil tie wires. See Figure B.8.

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; therefore it must
either be untangled or discarded.
