WELDING PROCESS

STICK (CONSTANT CURRENT) WELDING

Connect welding cables to the "TO WORK" and
"ELECTRODE" studs. Start the engine. Set the
"Polarity" switch to the desired polarity. Set the
"RANGE" switch to a setting that is equal to or slightly
greater than the desired welding current. (The
"RANGE" dial marking indicates the maximum current
for that range). Fine adjustment of the welding current
is made by adjusting the output "CONTROL" or
remote control. For best arc stability, use settings
5 through 10.
The Ranger 8 can be used with a broad range of AC
and DC stick electrodes. See "Welding Tips 1"
included with the Ranger 8 for electrodes within the
rating of this unit and recommended welding currents
of each.

TIG (CONSTANT CURRENT) WELDING

The K930-[ ] TIG Module installed on a Ranger 8 pro-
vides high frequency and shielding gas control for AC
and DC GTAW (TIG) welding processes. The TIG
Module allows full range output control. Afterflow time
is adjustable from 0 to 55 seconds.
When using the Ranger 8 for AC TIG welding of
aluminum, the following settings and electrodes are
recommended:

1/8 70, 90, or 125

The K930-[ ] TIG Module should be used with the
Ranger 8 on high idle to maintain satisfactory opera-
tion. It can be used in the AUTO position but the
delay going to flow idle after welding is ceased will be
increased if the AFTERFLOW CONTROL is set above
10 seconds.

The Ranger 8 is recommended for limited "MIG" weld-
ing (GMAW - gas metal arc welding). The recom-
mended electrodes are .030" and .035" L-50 and L-56.
They must be used with a blended shielding gas such
