WELDING PROCESS

For any electrodes the procedures should be kept within the rating of the machine. For electrode infor- mation see the appropriate Lincoln publication.

Stick (Constant Current) Welding

Connect welding cables to the “+” and - studs. Start the engine. The “RANGE” switch markings indicate the maximum current for that range as well as the typ- ical electrode size for that range. The “OUTPUT” Control provides fine adjustment of the welding cur- rent within the select range. For maximum output with- in a selected range set the “OUTPUT” Control at 10. For minimum output within a selected range set the “OUTPUT” Control at 5. (“OUTPUT” Control settings below 5 may reduce arc stability) For best overall welding performance set the “RANGE” Switch to the lowest setting and the OUTPUT” Control near the maximum to achieve the desired welding current.

TIG (CONSTANT CURRENT) WELDING

The K930-[ ] TIG Module installed on a EAGLE 10,000 provides high frequency and shielding gas control for GTAW (TIG) welding processes. Output Control is from the Eagle 10,000. The control on the TIG Module is not functional. After flow time is adjustable from 0 to 55 seconds. A K814 Arc Start Switch is required.

The K930-[ ] TIG Module should be used with the EAGLE 10,000 on HIGH IDLE to maintain satisfactory operation. It can be used in the AUTO position but the delay going to flow idle after welding is ceased will be increased if the AFTER FLOW CONTROL is set above 10 seconds. A K814 Arc Start Switch is required.

WIRE FEED WELDING PROCESSES (CONSTANT VOLTAGE)

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

The EAGLE 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 EAGLE 10,000 are shown in the following table:

ARC GOUGING

The EAGLE 10,000 can be used for limited arc goug- ing.

Set the Range switch to adjust output current to the desired level for the gouging electrode being used according to the ratings in the following table:
