WIRE DRIVE ROLL

The drive rolls installed with the POWER MIG® 215XT have two grooves one for .035(0.9mm) wire and the other for .045(1.2mm) wire. Drive roll size is indicated by the stenciling on the exposed side of the drive roll.

WIRE SIZE CONVERSION PARTS

The POWER MIG® 215XT is rated to feed .025 through .045" (0.6-1.2 mm) solid or cored electrode sizes.

The drive roll kits and Magnum 250L gun and cable parts are available to feed different sizes and types of electrodes. See Accessories section.

1.Open the Wire Drive Compartment Door

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

3.Place the Optional Adapter on the spindle

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

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 direction when feeding so as to be de- reeled from top 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.

5.Remove the inside wire guide plate.

6.Replace the drive rolls and inside wire guide with a set marked for the new wire size. NOTE: Be sure that the gun liner and contact tip are also sized to match the selected wire size.

7.Manually feed the wire from the wire reel, over the drive roll groove and through the wire guide and then into the brass bushing of the gun and cable assembly.

8.Replace the outside wire guide retaining plate by tightening the two large knurled screws. Reposition the adjustable pressure arm to its original position to apply pressure. Adjust pressure as necessary.

WIRE REEL LOADING - READI-REELS, SPOOLS OR COILS

To Mount a 30 Lb. (14 kg) Readi-Reel Package (Using the Molded Plastic K363-P Readi-Reel Adapter:)

CAUTION

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.

-----------------------------------------------------------------------------------------------

10.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.

(For 13-14 lb. (6 Kg) Innershield coils, a K435 Coil Adapter must be used).

1.Open the Wire Drive Compartment Door

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

3.Place the spool on the spindle making certain the spindle brake pin enters one of the holes in the back side of the spool (Note: an arrow mark on the spindle lines up with the brake holding pin to assist in lining up a hole). Be cer- tain the wire comes off the reel in a direction so as to de- reel from the top of the coil.

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