RETURN TO MAIN MENU ® RANGER 225 GXT IM969 December, 2008 For Machines with Code Number 11522 Safety Depends on You Lincoln arc welding and cutting equipment is designed and built with safety in mind. However, your overall safety can be increased by proper installation ... and thoughtful operation on your part. DO NOT INSTALL, OPERATE OR REPAIR THIS EQUIPMENT WITHOUT READING THIS MANUAL AND THE SAFETY PRECAUTIONS CONTAINED THROUGHOUT. And, most importantly, think before you act and be careful.
i i SAFETY WARNING CALIFORNIA PROPOSITION 65 WARNINGS Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm. The Above For Diesel Engines The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. The Above For Gasoline Engines ARC WELDING CAN BE HAZARDOUS.
ii ii SAFETY ARC RAYS can burn. 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. 3.b. Insulate yourself from work and ground using dry insulation. Make certain the insulation is large enough to cover your full area of physical contact with work and ground.
iii iii SAFETY WELDING and CUTTING 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. Avoid welding near hydraulic lines. Have a fire extinguisher readily available. 6.b.

A-2 A-2 INSTALLATION SAFETY PRECAUTIONS WARNING Do not attempt to use this equipment until you have thoroughly read the engine manufacturerʼs manual supplied with your welder. It includes important safety precautions, detailed engine starting, operating and maintenance instructions, and parts lists. -----------------------------------------------------------------------ELECTRIC SHOCK can kill. • Do not touch electrically live parts or electrode with skin or wet clothing.
INSTALLATION A-3 3. Proper placement of the equipment on the trailer to insure stability side to side and front to back when being moved and when standing by itself while being operated or serviced. FUEL Fill the fuel tank with clean, fresh, lead-free gasoline. Observe fuel gauge while filling to prevent overfilling. 4. Typical conditions of use, i.e., travel speed; roughness of surface on which the trailer will be operated; environmental conditions. 5.
A-4 A-4 INSTALLATION WELDING OUTPUT CABLES ADDITIONAL SAFETY PRECAUTION With the engine off, connect the electrode and work cables to the studs provided. These connections should be checked periodically and tightened if necessary. Loose connections will result in overheating of the output studs. When welding at a considerable distance from the welder, be sure you use ample size welding cables. Listed below are copper cable sizes recommended for the rated current and duty cycle.
A-5 INSTALLATION A-5 • LOCATION / VENTILATION The welder should be located to provide an unrestricted flow of clean, cool air to the cooling air inlets and to avoid heated air coming out of the welder recirculating back to the cooling air inlet. Also, locate the welder so that engine exhaust fumes are properly vented to an outside area. STACKING RANGER® 225 GXT machines cannot be stacked. CONNECTION OF LINCOLN ELECTRIC WIRE FEEDERS WARNING Shut off welder before making any electrical connections.
A-6 A-6 INSTALLATION WELDER OPERATION 120/240 VOLT DUAL VOLTAGE RECEPTACLE WELDER OUTPUT • Maximum Open Circuit Voltage at 3700 RPM is 80 Volts RMS. • 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. Duty Cycle for the RANGER® 225 GXT is 100%.
A-7 A-7 INSTALLATION TABLE lll ELECTRICAL DEVICE USE WITH THE RANGER® 225 GXT. Type Common Electrical Devices Possible Concerns Resistive Heaters, toasters, incandescent light bulbs, electric range, hot pan, skillet, coffee maker. NONE Capacitive TV sets, radios, microwaves, appliances with electrical control. Voltage spikes or high voltage regulation can cause the capacitative elements to fail.
A-8 INSTALLATION AUXILIARY POWER WHILE WELDING Simultaneous welding and power loads are permitted by following Table I. The permissible currents shown assume that current is being drawn from either the 120V or 240V supply (not both at the same time). Also, the “Output Control” is set at “10” for maximum auxiliary power. TABLE I SIMULTANEOUS WELDING AND POWER Output Selector Setting * Permissible Power Watts (Unity Power Permissible Auxiliary Current in Amperes Factor) @ 120V *-or- @ 240V Max.
A-9 INSTALLATION Figure 1 CONNECTION OF RANGER® 225 GXT TO PREMISES WIRING WARNING Connection of RANGER® 225 GXT to premises wiring must be done by a licensed electrician and must comply with the National Electrical Code and all other applicable electrical codes.
