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 gun trigger to feed wire

against surface. Tighten knob so wire

does not slip. Do not overtighten. If con-

tact tip is completely blocked, wire should

slip at the feeder (see pressure adjust-

ment above).Cut wire off. Close cover.
