TO INSTALL WIRE:
1. Loosen top idler tensioner, rotating counter-clockwise
2. Flip tensioners 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 us.
5. Thread straightened 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 clamp to
prevent the wire from arcing
