GENERAL DESCRIPTION

The RANGER 300 is a diesel-engine driven, multi- process AC and DC arc welder and AC power genera- tor for commercial and residential applications. As a generator it can supply up to 12,000 continuous watts of 120/240 volt, 60 Hz, single-phase AC power to operate AC power tools, battery chargers, and light- ing; it can also be used to provide standby power. As a welder it provides 300 amps of AC current for weld- ing with AC stick electrodes or 300 amps of DC cur- rent for DC stick welding. The RANGER 300 can also perform AC/DC TIG welding and DC semiautomatic wire feed welding.

The engine used on the Ranger 300 machines is the Kubota "Super Five" water-cooled, 3 cylinder DH905 engine. The DH905 has an offset piston design with built in steel strut and a more rigid crank-case. The Kubota "Three Vortex Combustion System" gives higher power output, lower fuel consumption, lower noise, and cleaner exhaust. The "Super Glow System" gives rapid pre-heating for easy starting in cold weather. The large oil sump adds to the long life of this engine. The high capacity 30 amp alternator gives fast charging of the 495 CCA battery. The engine is extremely smooth and has very low vibra- tion, even at low idle speed.

The Ranger 300 machines are housed in a heavy gauge steel case that is protected by a durable pow- der paint finish. The case is completely insonorized for remarkably quiet operation. An easy to open hinged door allows access to the engine for single side ser- vice. The welder alternator has all copper windings and a high temperature insulation system that includes three coats of electrical grade varnish.
