OPERATION

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.

b)When loading 0.030, 0.035 and 0.045" electrode, be certain the coil is placed on the reel so that 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 needed for trouble free wire feeding. See Figure B.8.

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.

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.

CAUTION

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.

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.

7.The mount for standard 50 and 60 pound electrode 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. 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 fric- tion fit.
