GENERAL DESCRIPTION

The RANGER® 305LPG is a gasoline engine pow- ered DC multi-process welding power source and 120

/240 volt AC power generator. The engine drives a generator that supplies three phase power for the DC welding circuit and single phase power for the AC

auxiliary outlets. The DC welding control system uses

state of the art Chopper Technology for superior welding performance. The RANGER 305LPG is NOT RECOMMENED for pipe thawing.

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® 305LPG con- sists of two 20 Amp-120 VAC GFCI (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.

ENGINE OPERATION

Before Starting the Engine:

Be sure the machine is on a level surface.

Open top engine door and remove the engine oil dipstick and wipe it with a clean cloth. Reinsert the dipstick and check the level on the dipstick.

Add oil (if necessary) to bring the level up to the full mark. Do not overfill. Close engine door.

See Engine Owner’s Manual for specific oil recom- mendations.

WARNING

The combustion of LPG fuel does produce carbon monoxide. Although the level of CO2 emis- sion is lower than gasoline com- bustion, the exhaust from the Ranger® 305LPG can kill.

Avoid breathing of vapor.

Keep sparks and flame away from tank.
