To Use the RANGER 9 for DC Wire Feed
Welding (Constant Voltage):
1. Connect one of the following: the LN-25, LN-7,
LN-8, or LN-742 Wire Feeder. Follow the installa-
tion instructions 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,
.052, and 1/16 Outershield 71 and 1/16
Outershield 70. Request Lincoln publication
GS-200 for additional information.
For MIG welding, the recommended electrodes
are .030, .035 and .045 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
or LN-742 or “HIGH” for the LN-7 or LN-8 and
start the gasoline engine. See ENGINE OPERA-
TION in this section of the manual.
4. Set the OUTPUT RANGE dial to either HIGH,
MED, or LOW depending on your wire size and
speed.
5. Set the POLARITY SWITCH to either WIRE FEED
DC+ or WIRE FEED DC- (red), 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 gasoline engine. See ENGINE OPERA-
TION 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.
