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.

DESIGN FEATURES - ALL MODELS

FOR WELDING:

•Excellent AC and DC constant current output for stick welding applications.

•40 to 300 amps constant current output with seven range settings.

•Excellent semi-automatic wire feed welding on con- stant voltage output range(s).

•TIG welding - full range on DC and up to 250 amps on AC.

•100% duty cycle rating on all output ranges.

•Remote control capability standard on all models. Amphenol receptacle for easy connection of Lincoln remote control accessories.

FOR AUXILIARY POWER:

•12,000 watts of 120/240 volt 60Hz AC auxiliary power.

•Power for tools, lights, electric pumps and for stand- by emergency power.

•Drive a 2 HP motor (provided it is started under no load).

•Two 15 amp industrial grade 120 volt duplex recep- tacles for up to 60 amps of 120 volt power.

•One 50 amp 120/240 volt dual voltage receptacle for up to 50 amps of 240 volt auxiliary power. Allows easy connection to premises wiring.

•Four 15 amp circuit breakers for 120V duplex recep- tacles and 2-50 amp circuit breakers for 240V recep- tacle.

•Weld and have AC power at the same time (within machine total capacity).

•Compatible with GFCI's (ground fault circuit inter- rupters).

OTHER FEATURES:

•Insonorized for extremely quiet operation (99LW(A) and 74 db(A) @ 23 ft (7m)).

•Kubota 3-cylinder, liquid cooled, diesel engine. Designed for long life, easy maintenance and excel- lent fuel economy and low noise.

•Engine always starts in low idle for minimum engine wear in cold weather.

•Manual operated lift pump for easy priming of engine if it runs out of fuel.

•Engine protection system shuts engine down on low oil pressure or over temperature of coolant.

•Indicator lights for low oil pressure, over temperature and battery charger low output.

•Engine Hour Meter standard on all models.

•Engine coolant recovery bottle eliminates air in radi- ator and makes it easy to check coolant level.

•Battery with 495 cold cranking amps.

•Straight through ventilation - cooling air for welder alternator enters front of machine and is exhausted out rear.

•Large capacity 10 gallon (38 l) fuel tank.

•Automatic idler reduces engine speed when not welding or drawing auxiliary power. Machine always starts in low idle. Reduces fuel consumption and extends engine life.

•Compact size fits many smaller trucks.

•Single side engine service with easy to open access door.

•Copper alternator windings and high temperature insulation for dependability and long life.

•Powder painted case and base for outstanding cor- rosion protection.
