AC/DC TIG (CONSTANT CURRENT) WELDING

1.Connect the K930-1 TIG Module to the RANGER 300. Follow the installation instructions provided with the kit.

2.Refer to the instruction manual with the TIG module (IM

528)for operation with a RANGER 300. And proper machine settings.

3.Set the RANGE switch to the appropriate setting for the electrode you are using. Refer to IM-528 with the TIG module or refer to Table B.2 for AC TIG welding.

4.Set the POLARITY SWITCH to the desired polarity.

5.Do not AC TIG weld on the 250 AC range setting. The output current may exceed the rating of the RANGER 300.

6.Start the arc and begin welding.

NOTE: When using the RANGER 300 for AC TIG welding of aluminum, the TIG Module is to be set for CON-

TINUOUS HF.

AFTER YOU FINISH WELDING:

1.Stop the engine.

2.Allow the electrode and work to cool completely.

3.Remove the work clamp from the work.

DC WIRE FEED WELDING (CV) WITH RANGER 300 DLX

1.Connect one of the following: the LN-25, LN-7 or LN-8 Wire Feeder.

2.Some recommended Innershield electrodes are:

.068 NR-211MP, .068 NR-232, NR-203 series, 5/64 NR-311, and 5/64 NS-3M also Lincore® 33 and 55 hardfacing electrodes can be used. 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.

4.Set the RANGE switch to either HIGH, MEDIUM HIGH, MEDIUM LOW, or LOW (CV-red) depend- ing 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 OUTPUT control to a setting between 1 and 10 that gives the most stable arc for the appli- cation. Try a higher RANGE switch setting if the arc is unstable.

7.Strike an arc and begin welding. The OUTPUT control can be adjusted while welding. DO NOT change the RANGE switch setting while welding. This can result in damage to the switch.

AFTER YOU FINISH WELDING:

1.Stop the engine.

2.Allow the work to cool completely.

3.Remove the work clamp from the work.
