OPERATION

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.
