OPERATION
POWER MIG 300
5. Rotate the spindle and adapter so the retaining
spring is at the 12 o'clock position.
6. Position the Readi-Reel so that it will rotate in a direc-
tion when feeding so as to be de-reeled from top the
of the coil.
7. Set one of the Readi-Reel inside cage wires on the
slot in the retaining spring tab.
8. Lower the Readi-Reel to depress the retaining spring
and align the other inside cage wires with the grooves
in the molded adapter.
9. Slide cage all the way onto the adapter until the
retaining spring "pops up" fully.
Check to be sure the retaining ring 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.

10. To remove Readi-Reel from Adapter, depress retain-
ing spring tab with thumb while pulling the Readi-
Reel cage from the molded adapter with both hands.
Do not remove adapter from spindle.
