4-step with crater fill.

(See Mode Selection and Display Control Keys sections).

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.

TO MOUNT A 30 LB (14 KG) READI - REEL PACKAGE USING THE MOLDED PLASTIC K363-P TYPE ADAPTER:

1)Make certain that the threaded locking collar is tight and securely locks the adapter on the spindle (see figure above).

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

3)Position the Readi-Reel so that it will rotate in a clockwise direction when feeding (wire is to be de- reeled from bottom of the coil).

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

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

6)Slide cage all the way onto the adapter until the retaining spring “pops up” fully.

of 2” (51mm) spindle K162H Kit. For 8” (200mm) spools, a K468 spindle adapter must be used.)

1)Remove the locking collar on the 2” (51mm) diameter spindle.

2)Place the spool on the spindle making certain the brake holding pin enters one of the holes in the back side of the spool. Be certain the wire comes off the reel in a clockwise direction when de-reeled from the bottom of the coil.

3)Replace and tighten the locking collar.

Feeding Electrode and Brake Adjustment

1)Turn the Readi-Reel or spool until the free end of the electrode is accessible.

WARNING

When feeding with the gun trigger, the electrode and drive mechanism are always “HOT” to work and ground and could remain “HOT” several seconds after the gun trigger is released.

___________________________________________

2)While tightly holding the electrode, cut off the bent end and straighten the first 6” (150mm). Cut off the first 1” (25mm). (If the electrode is not properly straightened, it may not feed or may not go into the outgoing guide tube causing a “birdnest”.)

3)Insert the free end through the incoming guide tube.

4)Press the Cold Inch key or the gun trigger and push the electrode into the drive roll.

5)Feed the electrode through the gun.

6)Adjust the brake tension with the thumbscrew on the spindle hub, until the reel turns freely but with little or no overrun when wire feeding is stopped. Do not overtighten.
