USING THE WIRE DRIVE ROLL

The drive roll provided with the WIRE-MATIC 250 has two grooves, one for.030-.035" (0.8-0.9mm) solid steel electrode, and the other for .045" (1.2mm) solid steel electrode. The welder is shipped with the drive roll installed in the .030-.035" (0.8-0.9mm) position as indi- cated by the stenciling on the exposed side of the drive roll. If .045" (1.2mm) electrode is to be used or one of the optional drive rolls is required, then the drive roll must be reversed or changed per the following instruc- tions. This information also appears on the Procedure Decal on the door inside the wire compartment.

PROCEDURE FOR CHANGING DRIVE ROLL

Different wire sizes may require changing the drive roll. The applicable wire sizes are stamped on the drive roll. Dual groove rolls must be installed so the side with the proper wire size stamp faces out.

1.Turn POWER SWITCH to OFF.

2.Release the pressure on the idle roll by swinging the pressure arm off the idle roll arm.

3.Remove the wire from the drive system.

4.Remove the wing screw from the drive roll.

5.Turn the drive roll over or change to another roll as required.

6.Replace the wing screw.

7.Check that the gun liner and contact tip are prop- erly sized for wire being used.

LOADING THE WIRE REEL

To mount a 22-30 lb. (10-14 kg) Readi-Reel package using the optional Readi-Reel Adapter (K363P):

1.Pull the spindle up out of the WIRE-MATIC 250 spindle mounting clips (V-brackets).

2.Snap the spindle into the Readi-Reel adapter so the spindle drive pin is engaged with the hole pro- vided in the Adapter.

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

4.Position the Readi-Reel so that it will rotate in a counterclockwise direction (as viewed from retain- ing spring side of Adapter) when wire is dereeled from the top of the coil as shown in Figure B.2.

FIGURE B.2 - Wire Reel Loading.

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

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

7.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 elec- trode.

8.Check that the mating surfaces of the spindle hubs and spindle mounting clips (V-brackets) are clear of dirt and debris, and that the adapter is fully engaged onto the spindle.

9.Lower the loaded spindle into the spindle mounting clips (V-brackets) so wire dereels from top of coil toward wire drive.
