INNERSHIELD COILS:

The spindle should be located in the lower mounting hole.

[For 8 in. (200 mm) spools, a K468 spindle adapter must first be slipped onto the spindle.]

[For 13 to 14 lb (6 kg) Innershield coils, a K435 Coil Adapter must be used.]

1.Depress the Release Bar on the Retaining Collar and remove it from the spindle.

2.Place the spool on the spindle, making certain the spindle brake pin enters one of the holes in the backside of the spool. Be certain the wire comes off the reel in a direction so as to de-reel from the bottom of the coil.

3.Re-install the Retaining Collar. Make sure that the Release Bar “pops up” and that the collar retainers fully engage the retaining groove on the spindle.

TO MOUNT A 50 to 60 lb (22.7 to 27.2 kg) COIL: (USING K1504-1 COIL REEL) (FOR 50 to 60 lb

READI-REELS A K438 READI-REEL ADAPTER MUST BE USED.)

The spindle should be located in the UPPER mount- ing hole.

1.With the K-1504-1 Coil Reel mounted on the 2 in. (51 mm) spindle (or with reel laying flat on the floor) loosen the spinner nut and remove the reel cover. See Figure B.7.

2.Before cutting the tie wires, place the coil of elec- trode on the reel so it unwinds from the bottom as the reel rotates.

3.Tighten the spinner nut against the reel cover as much as possible by hand, using the reel cover spokes for leverage. DO NOT hammer on the spinner nut arms.

4.Cut and remove only the tie wire holding the free end of the coil. Hook the free end around the rim of the reel cover and wrap it around to secure. Cut and remove the retaining 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 “backlash” of the coil, which may tangle the wire. A tangled coil will not feed, so it must either be untangled or discarded.

5.Be sure the coil is engaged with the spindle brake pin and the Release Bar and Retaining Collar “pops up” and that the collar retainers fully engage the retaining groove on the spindle.
