Pressure drive settings range from 1 to 8 with 8 being the maximum setting.

.For aluminum (soft) wire set pressure drive setting at 4 or below.

.Be sure that gun has proper size liner for the welding wire size.

When installing gun, the liner should extend into the PD continuous guide (or exit guide if used) as far as possible without interfering with the guide.

Install gun. Lay gun cable out straight. Cut off end of wire. Push wire through guide up to drive rolls; continue to hold wire. Press Jog button to feed wire out gun.

To adjust drive roll pressure, hold nozzle about 2 in (51 mm) from nonconductive

surface and press gun trigger to feed wire against surface. Adjust pressure drive lever 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.
