To Use the RANGER 10-LX for DC Wire
Feed Welding (Constant Voltage):
1. Connect one of the following: the LN-25, LN-7 or
LN-8 Wire Feeder. Follow the installation instruc-
tions in the Accessories section of this manual.
2. Some recommended Innershield electrodes are:
NR-211MP, NR-311, NR-203 series, as well as
Lincore
®
33 and 55 hardfacing electrodes.
Diameters from .035 (0.9mm) up to and including
5/64” (2.0mm) can be used. 5/64” (2.0mm) NS-
3M can be used in limited applications. Cable
length and other conditions can affect the ultimate
results of this application. Request Lincoln publi-
cation N-675 for additional information.
Recommended Outershield electrodes are .045
(1.1 mm), .052 (1.3 mm), and 1/16 (1.6 mm)
Outershield 71 and 1/16 (1.6 mm) Outershield 70.
Request Lincoln publication GS-200 for additional
information.
For MIG welding, the recommended electrodes
are .030 (0.8 mm), .035 (0.9 mm) and .045
(1.1 mm) L-50 and L-56. You must use a blended
shielding gas such as C25 (75% Argon, 25% CO
2
).
Request Lincoln publication GS-100 for additional
information.
3. Set the IDLER CONTROL to “AUTO” for the LN-25
“HIGH” for the LN-7 or LN-8 and start the diesel
engine. See Engine Operation in this section of
the manual.
4. Set the OUTPUT RANGE dial to either HIGH,
MEDIUM HIGH, MEDIUM LOW, or LOW depend-
ing on your wire size and speed.
5. Set the POLARITY SWITCH to either WIRE FEED
DC+ or WIRE FEED DC- (white), depending on the
electrode.
6. Set the FINE OUTPUT CONTROL to a setting that
gives the most stable arc for the application.
7. Strike an arc and begin welding.
After you finish welding:
1. Stop the engine. See Engine Operation in this
section of the manual.
2. Allow the work to cool completely. The wire gun
and wire are “cold.”
3. Remove the work clamp from the work.
