GENERAL DESCRIPTION

The RANGER® 225 GXT is a twin-cylinder, gasoline driven, multiprocess arc welder and AC power gener- ator. It is built in a heavy gauge steel case for durabili- ty on the job site.

WELDER CONTROLS - FUNCTION AND OPERATION

ENGINE SWITCH

The engine switch is used to Start the Engine, Select High Idle or Auto Idle while the engine is running, and stop the Engine.

When placed in the “OFF” position, the ignition circuit is de-energized to shut down the engine.

When held in the “START” position, the engine starter motor is energized.

When in “HIGH IDLE” ( ) position, the engine will run continuously at high idle.

When in “AUTO IDLE” ( / ) position, the engine will run continuously and the idler operates as follows:

Welding

When the electrode touches the work, the welding arc is initiated and the engine accelerates to full speed.

After welding ceases (and no auxiliary power is being drawn), the engine will return to low idle after approximately 10 to 14 seconds.

Auxiliary Power

With the engine running at low idle and auxiliary power for lights or tools is drawn (approximately 100-150 watts or greater) from the receptacles, the engine will accelerate to high speed. If no power is being drawn from the receptacles (and not welding) for 10-14 seconds, the idler reduces the engine speed to low idle.
