351040, Miami, Florida 33135 or CSA Standard W117.2-1974. 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.

The welder should be located to provide an unrestrict- ed flow of clean, cool air to the cooling air inlets and to avoid restricting the cooling air outlets. Also, locate the welder so that the engine exhaust fumes are prop- erly vented to an outside area. STACKING Ranger 250 machines cannot be stacked.
The standard muffler included with this welder does not quali- fy as a spark arrester. When required by local regula- tions, a suitable spark arrester, such as the K1898-1 must be installed and properly maintained.
To prevent dangerous electric shock, other equipment to which this engine driven welder supplies power must: INSTALLATION 1. Be grounded to the frame of the welder using a grounded type plug. 2. Be double insulated. Do not ground the machine to a pipe that carries explosive or combustible material.
Table A.1 lists recommended cable sizes and lengths for rated current and duty cycle. Length refers to the distance from the welder to the work and back to the welder. Cable diameters are increased for long cable lengths to reduce voltage drops.

• Only qualified personnel should operate this equipment. ADDITIONAL SAFETY PRECAUTIONS Always operate the welder with the hinged door closed and the side panels in place as these pro- vide maximum protection from moving parts and insure proper cooling air flow.
WELDING CONTROLS: 1. OUTPUT CONTROL: The CONTROL dial provides continuous control of the welding current or welding voltage depending on the selected welding mode. This control is not active in the CC-STICK, DOWN HILL PIPE, and CV-WIRE modes when a remote control or wire feeder with remote control is connected to either the 6 pin or 14 pin Amphenol.
Amphenol, the auto-sensing circuit in the Ranger 250 automatically switches the OUTPUT control from con- trol at the welder to remote control . When using the TOUCH START TIG mode with a TIG Module connected to the Ranger 250, the OUT-...
NOTE: A fuel shut off valve is not required on the Ranger 250 because the fuel tank is mounted below the engine. WELDER OPERATION DUTY CYCLE is the percentage of time the load is being applied in a 10 minute period. For example, a 60% duty cycle represents 6 minutes of load and 4 minutes of no load in a 10 minute period.
.045 (1.1 mm), Super Arc L-50 and L-56, .035 (0.9 mm) and .045 (1.1 mm) Blue Max MIG 308 LS. Contact your local authorized Lincoln Electric Distributor or the Lincoln Electric Company for specific wires used on certain applications with this machine.

ARC GOUGING The Ranger 250 can be used for limited arc gouging. For optimal performance, set the MODE switch to CC- STICK and the ARC CONTROL to +10. Set the CONTROL knob to adjust output current to the desired level for the gouging electrode being used according to the ratings in the following table.
400 amps, 100% duty cycle. K857 25 ft (7.5m) or K857-1 100 ft. (30.4m) REMOTE CON- TROL - Portable control provides same dial range as the output control on the welder. Has a convenient 6 pin plug for easy connection to the welder. ACCESSORIES...
SAFETY PRECAUTIONS WARNING • Have qualified personnel do all maintenance and troubleshooting work. • Turn the engine off before working inside the machine or servicing the engine. • Remove guards only when necessary to perform maintenance and replace them when the maintenance requiring their removal is complete.
ENGINE OIL CHANGE Drain the oil while the engine is warm to assure rapid and complete draining. • Remove the oil filler cap and dipstick. Remove the yellow cap from the oil drain valve and attach the flexible drain tube supplied with the machine. Push in and twist the drain valve counterclockwise.
AIR FILTER PAPER ELEMENT 1. Loosen the cover retaining knob and remove the cover. 2. Remove the pre-cleaner from the paper element. 3. Remove the element cover nut, element cover, and paper element. 4. Do not wash the paper element or use pressurized air, as this will damage the element.
CONNECTING A BATTERY CHARGER — • remove battery from welder by disconnecting negative cable first, then positive cable and battery clamp. When reinstalling, connect negative cable last. Keep well ventilated.
