For any electrodes the procedures should be kept with-

see the appropriate Lincoln publication.
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. The "RANGE"
switch markings indicate the maximum current for that
range as well as the typical electrode size for that
range. The "OUTPUT" Control provides fine adjust-
ment of the welding current within the select range. For
maximum output within a selected range set the "OUT-
PUT" Control at 10. For minimum output within a
selected range set the "OUTPUT" Control at 5. ("OUT-
PUT" Control settings below 5 may reduce arc stabili-
ty) For best overall welding performance set the
"RANGE" Switch to the lowest setting and the OUT-
PUT" Control near the maximum to achieve the
desired welding current.

The RANGER® 10,000 can be used with a broad
range of AC and DC stick electrodes. See "Welding
Tips 1" included with the RANGER® 10,000 for elec-
trodes within the rating of this unit and recommended
welding currents of each.
TIG (CONSTANT CURRENT) WELDING
The K930-[ ] TIG Module installed on a RANGER®
10,000 provides high frequency and shielding gas con-
trol for AC and DC GTAW (TIG) welding processes.
Output control is from the RANGER® 10,000. The out-
put control on the TIG Module is not functional. After
flow time is adjustable from 0 to 55 seconds.
When using the RANGER® 10,000 for AC TIG welding
of aluminum, the following settings and electrodes are
recommended:

The K930-[ ] TIG Module should be used with the
1/16 90 or 145
RANGER® 10,000 on high idle to maintain satisfactory
operation. It can be used in the AUTO position but the
delay going to low idle after welding is ceased will be
increased if the AFTER FLOW CONTROL is set above 10
seconds.
NOTE: For AC TIG Welding, the maximum TIG welding
output currents on each range setting will be approxi-
mately 50% higher than those marked on the nameplate.
This is due to the special nature of the AC TIG welding
arc. Do not AC TIG weld on the 225AC range setting. The
output current may exceed the rating of the RANGER®
10,000.

The RANGER® 10,000 is recommended for limited "MIG"
welding (GMAW - gas metal arc welding). The recom-
mended electrodes are .030" and .035" L-50 and L-56.
