    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.

    If not done properly, it can result in fire, explosion, damage to wiring which may make it unsafe, dam- age to pipes, burning up the welder, or other haz- ards. Do not use a welder to thaw pipe before reviewing Lincoln Bulletin E695.1 (dated October 1987 or later.)

    Leaving the doors open changes the designed air flow and may cause overheating. The welder should be located to provide an unrestrict- ed flow of clean, cool air. Also, locate the welder so that the engine exhaust fumes are properly vented to an outside area.

    Consult the engine operation manual for spe- cific engine manufacturer’s recommendations. Upon receipt of the welder, check the engine dipstick to be sure the oil is at the “full” mark. DO NOT OVERFILL. Fuel Fill the fuel tank with the grade of fuel recommended in the Engine Operator’s Manual.

    10°F (-12°C) and freezing, use the standard “Thermostart” starting system installed on all engines. Follow the instructions on the nameplate and in the engine manual shipped with the welder. With fully charged batteries and the proper weight oil, the “Thermostart” system operates satisfactorily even down to about 0°F (-18°C).

    60% duty cycle. Duty cycle is based on a ten minute period; thus, the welder can be loaded at rated output for six minutes out of every ten minute period. The Lincoln “plus output” rating at 60% duty cycle 250 amperes at 40 volts.

  • Page 16: Auxiliary Power, Maintenance, General Instructions For Diesel Engine Welders

    ----------------------------------------------------------- General Instructions for Diesel Engine Welders 1. Blow out the welder and controls with an air hose at least once every two months. In particularly dirty locations, this cleaning may be necessary once a week. Use low pressure air to avoid driving dirt into the insulation.

  • Page 17: Cooling System, Bearings, Commutator And Brushes

    Never use emery cloth or paper for this purpose. NOTE: If the welder is used in dirty or dusty locations, or if the welder is not used for prolonged periods of time, it may be necessary to clean the commutator and slip rings more often.

  • Page 18: Maintenance, Idler Maintenance, Nameplate, Troubleshooting

    3. Proper operation of the idler requires good ground- ing of the printed circuit board (through its mount- ing), reed switch and battery. 4. If desired, the welder can be used without automat- ic idling by setting the “Idler Control” switch to the “High Idle” position.

    TROUBLE A. Machine fails to hold the “heat” consistently. B. Welder starts but fails to gener- ate current. C. Welding arc is loud and spat- ters excessively. See FLASHING THE FIELDS on following page. TROUBLESHOOTING CAUSE 1. Rough or dirty commutator.

  • Page 20: Flashing The Fields

    See the wiring diagram. With the engine NOT running, touch the positive battery terminal to the positive brushholder. Remove the battery from the circuit. 4. Replace the exciter cover. Start the welder and the generator voltage should build up. TROUBLESHOOTING CAUSE 1.
