RETURN TO MAIN MENU IM692 MULTI-SOURCE October, 2000 For use with machines Code 10668 Safety Depends on You Lincoln arc welding 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 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 INSTALLATION A-2 INPUT AND GROUNDING CONNETIONS WARNING ELECTRIC SHOCK can kill. • Have an electrician install and service this equipment. • Turn the input power off at the fuse box before working on equipment. • Do not touch electrically hot parts. • The Multi-Source power supply should not be used if the green Safe Output light is not lit. The machine is designed to open its input contactor if output voltage peaks exceed the limits set by certain approval agencies.
A-3 A-3 INSTALLATION OUTPUT CABLES, CONNECTIONS AND LIMITATIONS The Multi-Source has two parallel connected output studs for positive and negative connections. Each one is rated to carry the full output current. For its maximum rated current at 100% duty cycle a minimum size of 4/0 AWG is recommended. Connection of Electrode and Work Leads to Output terminals. RECOMMENDED EQUIPMENT / INTERFACE The Multi-Weld 350 (K1752-1) is the recommended means by which to control the Multi-Source power supply.
B-1 OPERATION SAFETY PRECAUTIONS WARNING ELECTRIC SHOCK can kill. • Do not touch electrically live parts or electrode with skin or wet clothing. • Insulate yourself from work and ground. • Always wear dry insulating gloves. -----------------------------------------------------------------------FUMES AND GASES can be dangerous. • Keep your head out of fumes. • Use ventilation or exhaust to remove fumes from breathing zone.

E-1 TROUBLESHOOTING E-1 HOW TO USE TROUBLESHOOTING GUIDE WARNING Service and Repair should only be performed by Lincoln Electric Factory Trained Personnel. Unauthorized repairs performed on this equipment may result in danger to the technician and machine operator and will invalidate your factory warranty. For your safety and to avoid Electrical Shock, please observe all safety notes and precautions detailed throughout this manual.
E-2 E-2 TROUBLESHOOTING Observe all Safety Guidelines detailed throughout this manual PROBLEMS (SYMPTOMS) POSSIBLE AREAS OF MISADJUSTMENT(S) RECOMMENDED COURSE OF ACTION Machine input contactor does not 1. Supply line fuse is blown. operate. 2. Contactor power circuit has an (White Power light off) open lead. 3. Broken power lead. 4. T2 internal thermal breaker open 5. Defective POWER ON/OFF Switch (S1). 7. Control circuit diode bridge open 8. Transformer iron rear thermostat open.
E-3 E-3 TROUBLESHOOTING Observe all Safety Guidelines detailed throughout this manual PROBLEMS (SYMPTOMS) POSSIBLE AREAS OF MISADJUSTMENT(S) Machine output doesn’t stay on. (Amber Thermal light on, fan running, digital Output display never reads greater than 100) 1. Cooling air blocked or limited. 2. Faulty output lead thermostat, SCR heat sink thermostat or connecting leads. 3. Ambient cooling air too hot. Machine output doesn’t stay on.
E-4 E-4 TROUBLESHOOTING Observe all Safety Guidelines detailed throughout this manual PC BOARD TROUBLESHOOTING GUIDE - FIRING P.C. BOARD 1. LEDs 1 through 9 must be lit when the Multi-Source is turned on and the Control board is sending an enable signal to the Firing board (pin 7 in P8 is low in reference to common at pin 12 in P5). 2. LEDs 7, 8, and 9 indicate AC power being supplied to the P.C. board from auxiliary windings on the main transformer (T1).
E-5 TROUBLESHOOTING E-5 Observe all Safety Guidelines detailed throughout this manual PC BOARD TROUBLESHOOTING GUIDE - CONTROL P.C. BOARD 1. The white Power light on the machine control panel indicates that the Control board power supply is being supplied by rectified secondary voltage from the Control transformer (T2) by way of the Power switch and transformer iron rear thermostat. 2. LED1 indicates machine output voltage. At normal output voltages, LED1 will be brightly lit. 3.
