�
For best wire feeding performance, be sure that the outlet cable has the proper size liner for the welding wire size being used. Also,
when the gun is installed, the liner extending from the back of the gun should be as close to the drive rolls as possible, without
touching.
Install gun. Lay gun cable out straight. Cut off end of wire. Push wire through guides up to drive rolls; continue to hold wire. Press Jog button
to feed wire out gun.
�
For soft wire or small diameter stainless steel wire, reduce drive roll pressure on the rear roll to half that of the front rolls.

�
To adjust drive roll pressure, hold nozzle about 2 in. (51 mm) from nonconductive surface and press jog button to feed wire against sur-
face. Tighten knob so wire does not slip. Do not overtighten. If contact tip is completely blocked, wire should slip at the feeder (see
pressure adjustment above). Cut wire off. Close cover.
