Set Weld Process Selector switch to
Wire + (DCEP) position.
Set Coarse Range switch to Wire/Low
(17-22 volts) position.
Set Fine Control to desired voltage
(arc length). Start with a low voltage
setting (about 4) to prevent burnback.
Set wire feed speed between 240-270
ipm. For 1/4 in. and thicker materials,
set Coarse Range switch to Wire/High
and Fine Control to 6. Increase/de-
crease Fine Control setting to in-
crease/decrease arc length.
