GENERAL DESCRIPTION

The RANGER 305D (CE) is a diesel engine powered DC multi-process welding power source and AC power generator. The engine drives a generator that supplies three phase power for the DC welding circuit and three phase and single phase power for the AC auxiliary outlets. The DC welding control system uses state of the art Chopper Technology (CT TM) for supe- rior welding performance.

FOR AUXILIARY POWER:

Start the engine and set the IDLER control switch to the desired operating mode. Full power is available regardless of the welding control settings providing no welding current is being drawn.

BREAK-IN PERIOD

Any engine will use a small amount of oil during its “break-in” period. For the diesel engine on the RANGER 305D (CE), break-in is about 50 running hours.

Check the oil every four hours during break-in. Change the oil after the first 50 hours of operation, every 100 hours thereafter. Change the oil filter at the second oil change.

CAUTION

During break-in, subject the RANGER 305D (CE) to moderate loads. Avoid long periods running at idle. Before stopping the engine, remove all loads and allow the engine to cool several minutes.
