•One 50 amp 120 V single phase AC dual voltage power receptacle with two 50 amp circuit breakers. Supplies up to 38 amps of 240 V AC and up to 76 amps of 120 V AC single phase auxiliary power per side to separate branch circuits (not in parallel). Allows easy connection to premises wiring.

•Welding and AC auxiliary power at the same time (within machine total capacity).

OTHER FEATURES

•Overhead valve, V-twin, 20 HP gasoline engine. Designed for long life, easy maintenance and excel- lent fuel economy.

•Engine protection system shuts the engine down with low oil pressure.

•Large maintenance-free battery. Group 58 with 435 cold cranking amps.

•Battery charging ammeter.

•Engine hour meter.

•Extended range 9 U.S. gallon (7.5 Imp. Gal., 34 liters) fuel tank.

•Automatic idler reduces engine speed when not welding or drawing auxiliary power. This feature reduces fuel consumption and extends engine life.

•Compact size fits crosswise in compact size pick-up truck.

•Copper alternator windings for dependability and long life.

•CSA approved.

RECOMMENDED APPLICATIONS

WELDER

The Ranger 275 provides excellent constant current DC welding output for stick (SMAW) welding and for TIG welding, and it offers constant voltage output for DC semiautomatic wire feed welding.

GENERATOR

The Ranger 275 gives AC power output for medium use demands.

LIMITATIONS

•The Ranger 275 is not recommended for any processes besides those that are normally per- formed using stick welding (SMAW), TIG welding (GTAW), MIG (GMAW) welding and Innershield® (FCAW) welding.

•The Ranger 275 is not recommended for pipe thawing.

•During welding, generator power is limited and out- put voltages can drop. Therefore, DO NOT OPER-

ATE ANY SENSITIVE ELECTRICAL EQUIPMENT WHILE YOU ARE WELDING. See Table B.4 for permissible simultaneous welding and auxiliary power loads.

ADDITIONAL SAFETY PRECAUTIONS

Always operate the welder with the roof and case sides in place as this provides maximum protection from moving parts and assures proper cooling air flow.

Read and understand all Safety Precautions before operating this machine. Always follow these and any other safety procedures included in this manual and in the Engine Owner’s Manual.

Only qualified personnel should install, use, or service this equipment.
