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% CO2). 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.
