Using the wire feed unit

TO INSTALL WIRE:

1. Loosen top tensioner arm, rotating counter-clockwise

2. Flip tensioner down, releasing top drive rolls.

3. Raise top drive rolls.

4. Inspect the drive roll to make sure that the groove size matches the wire diameter. Reversal of the

lower roller may be necessary. To reverse the roller, remove the thumb screw securing the drive roll.

Pull the drive roll off, and flip the drive roll over. Reassemble and tighten roller. If larger roller is needed,

contact R-Tech. Be careful to replace the woodruff key between outer roller and shaft.

5. Thread straightened welding wire over grooves in lower drive roll fully through until it begins to start

threading into the gun section. Lower upper drive rolls onto lower drive roll, keeping wire in the groove.

6. Raise tensioner back into place. Tighten slightly so wire will feed. Notice markings on tensioner for

future reference.

7. Hold torch straight out as possible. Press gun trigger to feed wire until the wire exits the end of the

torch.

8. Adjust tensioner clockwise until drive rolls will not slip when wire comes into contact with surface and

the wire will curl up on end. Remember to keep wire away from metal that is attached to the work

clamp to prevent the wire from arcing
