GENERAL DESCRIPTION

The RANGER 305G is a gasoline engine powered DC multi-process welding power source and 120 / 240 volt AC power generator. The engine drives a genera- tor that supplies three phase power for the DC weld- ing circuit and single phase power for the AC auxiliary outlets. The DC welding control system uses state of the art Chopper Technology (CT tm) for superior weld- ing performance.

DESIGN FEATURES

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.

The auxiliary power of the RANGER 305G consists of two 20 Amp-120 VAC (5-20R) duplex receptacles and one 50 Amp 120/240 VAC (14-50R) receptacle. The 240 VAC receptacle can be split for single phase 120 VAC operation.
