WELDING PROCESS

For any electrodes the procedures should be kept
within the rating of the machine. For electrode infor-
mation 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
“OUTPUT” 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.

CURRENT RANGE

ELECTRODE SIZE

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 electrodes with-
in 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 control for
AC and DC GTAW (TIG) welding processes. Output
control is from the Ranger 10,000. The output 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 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.

WIRE FEED WELDING PROCESSES
(CONSTANT VOLTAGE)

The Innershield® electrode recommended for use with
the RANGER 10,000 is NR

®

-211-MP. The electrode

sizes and welding ranges that can be used with the
RANGER 10,000 are shown in the following table:

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.
They must be used with a blended shielding gas such as
C25 (75% Argon - 25% CO

2

). The welding ranges that

can be used with the RANGER 10,000 are shown in the
following table:

ARC GOUGING

The Ranger 10,000 can be used for limited arc gouging.

Set the Range switch to adjust output current to the
desired level for the gouging electrode being used
according to the ratings in the following table:
