WIRE LOADING

Loading a 22 to 30 Lb. (10 to 14 kg) Readi-Reel Package Using the Molded Plastic K363-P Readi-Reel Adapter:

The Spindle should be located in the LOWER mounting hole.

1)Depress the Release Bar on the Retaining Collar and remove it from the spindle. NOTE: Earlier spindles used a threaded collar. See Figure B.7a or B.7b.

2)Place the Adapter on the spindle.

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.

4)Rotate the spindle and adapter so the retaining spring is at the 12 o'clock position.

5)Position the Readi-Reel so that it will rotate in a direction when feeding so as to be de-reeled from the bottom of the coil.

6)Set one of the Readi-Reel inside cage wires on the slot in the retaining spring tab.

7)Lower the Readi-Reel to depress the retaining spring and align the other inside cage wires with the grooves in the molded adapter.

8)Slide the cage all the way onto the adapter until the retaining spring "pops up" fully.

WARNING

Check to be sure the Retaining Spring has fully returned to the locking position and has SECURELY locked the Readi-Reel Cage in place. Retaining Spring must rest on the cage, not the welding electrode.

___________________________________________

9)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.
