This section provides general
guidelines and may not suit all
applications.

The control panel shows the typi-
cal settings for welding with a
7018 (1/8 in.) electrode. Consult
the amperage selection tables
below if welding with other elec-
trodes.
1 Work Clamp
2 Electrode Holder
Connect Work cable to Work terminal
and Electrode holder cable to Elec-
trode terminal on welding generator.
.
Be sure to use the correct size
weld cables (see Section 5-9).
.
For best performance, set the
Coarse Range switch to the low-
est range that covers the desired
weld amperage. Use the Fine
control to select the desired am-
perage within the range se-
lected. When properly set, the
Fine control is normally set at 7
or higher.
Typical Settings For 7018 (1/8 in.)
Electrode:
>
Set Weld Process Selector
switch to DC position.
>
Set Coarse Range switch to
70-150 (1/8 in.) position.
>
Set Fine control at 7 or higher
for best results.
