GENERAL DESCRIPTION

The Ranger 275 is an engine driven, multi-process DC arc welder and AC power generator for commer- cial and residential applications. As a generator it can supply up to 9,000 continuous watts of 120/240 volt, 60 Hz, single-phase AC power to operate AC power tools, battery chargers, and lighting; it can also be used to provide standby power. As a welder it pro- vides up to 300 amps of DC current for DC stick weld- ing and DC semiautomatic wire feed welding. The Ranger 275 can also perform DC TIG welding.

DESIGN FEATURES

FOR WELDING:

•DC constant current output for stick and TIG weld- ing - Two continuous CC output settings of 20 to 300 amps, one for general purpose stick and tig welding and one with a fixed controlled slope for out of position and pipe welding. The STICK-TIG mode includes an arc force control.

•DC constant voltage output for MIG and Flux Cored wire welding - One continuous CV welding range of 11 to 32 volts. Excellent MIG welding with CO2 and blended gas. A pinch control allows the arc to be fine tuned from “soft “ to “crisp”. The recommended wire feeder is the K446 LN-25 with the K624-1 42 Volt Remote Output Control Module or the K449 LN- 25 with an internal contactor.

•100% duty cycle at 275 amps output.

•Remote control capability. Nine pin and fourteen pin connectors for easy connection of Lincoln wire feeders and remote control accessories. The 14 pin connector includes power for 42 VAC wire feeders.

•Internal “Solid State” contactor allows for the selec- tion of “hot” or “cold” output terminals.

FOR AUXILIARY POWER

•9,000 watts of 240 V AC, 60Hz auxiliary power.

•Power for tools, 120/240 lights, electric pumps and for standby emergency power.

•Power a 5 HP motor (provided it is started under no load).

•Two 15 amp industrial grade 120 V AC duplex receptacles for up to 60 amps of 120 VAC power.
