A Free copy of “Arc Welding Safety” booklet E205 is available from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199. BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
ELECTRIC SHOCK can kill. 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.

WELDING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas.

Thank You Please Examine Carton and Equipment For Damage Immediately When this equipment is shipped, title passes to the purchaser upon receipt by the carrier. Consequently, Claims for material damaged in shipment must be made by the purchaser against the transportation company at the time the shipment is received.
Only qualified personnel should install, use, or service this equipment. LOCATION AND VENTILATION Whenever you use the Ranger 275, be sure that clean cooling air can flow through the machine’s engine and the machine case. Avoid dusty, dirty areas. Also, keep the machine away from heat sources.
• Keep sparks and flame away from the fuel tank. ------------------------------------------------------------------------ The Ranger 275 is shipped with the engine filled with SAE 10W-30 oil. CHECK THE OIL LEVEL BEFORE YOU START THE ENGINE. If it is not full, add enough oil to fill it to the full mark.
Fill the fuel tank with clean, fresh regular grade lead- free gasoline. Observe the fuel gauge while filling to prevent overfilling. The Ranger 275 has a 9 U.S. gallon (7.5 Imp. Gal., 34L) fuel tank mounted below the generator. See the Engine Owners Manual for more details about the fuel.
Do not ground the machine to a pipe that carries explosive or combustible material. ------------------------------------------------------------------------ When the Ranger 275 is mounted on a truck or a trail- er, the machine generator ground stud MUST be securely connected to the metal frame of the vehicle.
AUXILIARY POWER RECEPTACLES, PLUGS, AND HAND-HELD EQUIPMENT The control panel of the Ranger 275 features three auxiliary power receptacles: See Figure B.1. • Two 15 amp, 120 volt duplex (double outlet) recepta- cles. • One 50 amp 120/240 volt single outlet receptacle.
VOLT PLUG NEMA TYPE 14-50 50 AMP, 120/240 VOLT RECEPTACLE Connection of Ranger 275 to premises wiring must be done by a licensed electrician and must comply with the National Electrical Code and all other applicable electrical codes. INSTALLATION Table A.1...
Only qualified personnel should operate this equip- ment. 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;...
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. OPERATION LIMITATIONS • The Ranger 275 is not recommended for any...
12. 6 PIN AMPHENOL: For attaching optional remote control equipment to the Ranger 275. 13. 14 PIN AMPHENOL: For attaching wire feeder con- trol cables to the Ranger 275 (Includes contactor clo- sure circuit, remote control circuit, wire feeder 115/42 volt power source).
DO NOT RUN THE ENGINE AT EXCESSIVE SPEEDS. The maximum allowable high idle speed for the Ranger 275 is 3750 RPM, no load. Do NOT adjust the governor screw on the engine. Severe per- sonal injury and damage to the machine can result if it is operated at speeds above the maximum rated speed.
Auxiliary Power OPERATION Stop the engine by placing the “Engine” switch in the “STOP” position. A fuel shut off valve is not required on the Ranger 275 because the fuel tank is mounted below the engine. ------------------------------------------------------------------------ TABLE B.1 K1641-1 Ranger 275 Kohler Engine .40 US gallons/hour...
The toggle switch on the control panel labeled “LOCAL/REMOTE” gives the operator the option of controlling the output at the welder control panel or at a wire feeder, TIG amptrol, or a K857 Remote Control that is connected to either the 6 pin or 14 pin amphe- nol connector.
OPERATION TIG WELDING The Ranger 275 can be used in a wide variety of DC Tungsten Inert Gas (TIG) welding applications. When used with the K930-1 or -2 TIG module, ratings are limited to 275A at a 60% duty cycle and 250A at a 80% duty cycle.
(5) TIG torch nozzles are typically made from alumina ceramic. Special applications may require lava nozzles, which are less prone to breakage, but cannot withstand high temperatures and high duty cycles. WIRE WELDING Connect a wire feeder to the Ranger 275 and set welder controls according to the instructions on the appropriate wire feeder connection diagram.
RANGER 275 TO START WELDING Touch electrode to work. Welding starts immediately and engine goes to high idle. Press Amptrol. Ranger 275 contactor closes. Welding starts immediately and engine goes to high idle. Press gun trigger, Ranger 275 contactor closes.
Full power is available regardless of the welding output settings, if no welding current is being drawn. The auxiliary power of the Ranger 275 consists of two 15 Amp-120VAC (5-15R) duplex receptacles and one 50 Amp 120/240 VAC (14-50R) receptacle.
K933-1 Four Wheel Undercarriage - Allows move- ment of the Ranger 275 by hand without lifting on smooth surfaces. Includes two rugged, hard molded wheels and two durable pneumatic tires. The spring loaded handle provides convenient, comfortable steer- ing.
Requires the K488 SG Control Module. Includes 25 feet (7.6 meters) of power cable. K488 SG Control Module - Controls wire speed and gas flow. Provides the required control interface between the Ranger 275 and the K487-25 Magnum Spool Gun. RANGER 275...
