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. The “RANGE” switch markings indicate the maximum current for that range as well as the typical electrode size for that range. The “OUTPUT” Control provides fine adjust- ment of the welding current within the select range. For maximum output within a selected range set the “OUT- PUT” Control at 10. For minimum output within a selected range set the “OUTPUT” Control at 5. (“OUT- PUT” Control settings below 5 may reduce arc stabili- ty) For best overall welding performance set the “RANGE” Switch to the lowest setting and the OUT- PUT” Control near the maximum to achieve the desired welding current.

The RANGER® 10,000 can be

used with a broad

range of AC and DC stick electrodes. See “Welding

Tips 1” included with the RANGER® 10,000 for elec-

trodes within the rating of this unit and recommended

welding currents of each.

 

TIG (CONSTANT CURRENT) WELDING

The K930-[ ] TIG Module installed on a RANGER® 10,000 provides high frequency and shielding gas con- trol for AC and DC GTAW (TIG) welding processes. Output control is from the RANGER® 10,000. The out- put control on the TIG Module is not functional. After flow time is adjustable from 0 to 55 seconds.

When using the RANGER® 10,000 for AC TIG welding of aluminum, the following settings and electrodes are recommended:

RANGER® 10,000 on high idle to maintain satisfactory operation. It can be used in the AUTO position but the delay going to low idle after welding is ceased will be increased if the AFTER FLOW CONTROL is set above 10 seconds.

For AC TIG Welding, the maximum TIG welding outputNOTE: currents on each range setting will be approxi- mately 50% higher than those marked on the nameplate. This is due to the special nature of the AC TIG welding arc. Do not AC TIG weld on the 225AC range setting. The output current may exceed the rating of the RANGER® 10,000.

WIRE FEED WELDING PROCESSES

(CONSTANT VOLTAGE)

The Innershield® electrode recommended for use with the RANGER® 10,000 is NR®-211-MP. The electrode sizes and welding ranges that can be used with the RANGER® 10,000 are shown in the following table:

The RANGER®

10,000 is recommended

for limited “MIG”

welding (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® 10,000 are shown in the

following table:
