Welding Process

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. Set the “RANGE” switch to a setting that is equal to or slightly greater than the desired welding current. (The “RANGE” dial marking indicates the maximum current for that range). Fine adjustment of the welding current is made by adjusting the output “CONTROL” or remote control. For best arc stability, use settings 5 through 10.

The Ranger 8 can be used with a broad range of AC and DC stick electrodes. See “Welding Tips 1” includ- ed with the Ranger 8 for electrodes within the rating of this unit and recommended welding currents of each.

TIG (Constant Current) Welding

The K930-[ ] TIG Module installed on a Ranger 8 pro- vides high frequency and shielding gas control for AC and DC GTAW (TIG) welding processes. The TIG Module allows full range output control. Afterflow time is adjustable from 0 to 55 seconds.

When using the Ranger 8 for AC TIG welding of alu- minum, the following settings and electrodes are recommended:

(Constant Voltage)

The only Innershield® electrode recommended for use with the Ranger 8 is NR®-211-MP. The electrode sizes and welding ranges that can be used with the Ranger

8 are shown in the following table:

The Ranger 8 is recommended for limited “MIG” weld- ing (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% CO2). The welding ranges that can be used with the Ranger 8 are shown in the following table:

The K930-[ ] TIG Module should be used with the Ranger 8 on high idle to maintain satisfactory opera- tion. It can be used in the AUTO position but the delay going to flow idle after welding is ceased will be increased if the AFTERFLOW CONTROL is set above 10 seconds.
