SECTION 3 - INSTALLATION ELECTRICAL INPUT CONNECTIONS 3-2. Electrical Input Requirements A. welding power source is designed to be operated from a three-phase, 60 Hertz, ac power supply which has a line volt age rating that corresponds with one of the electrical input voltages shown on the nameplate. Consult the local electric utility if there is any question about the type of electrical This system available at the installation site or how proper tions to the welding power source are to be made.
230 VOLTS It is recommended that a terminal lug of adequate amperage capacity be attached to the ends of the in put and ground conductors. The hole diameter in the terminal lug must be of proper size the line and ground terminal studs. to U accommodate . Connect the three input conductors to the line terminals on the contactor. Connect the ground conductor to the terminal labeled GROUND on the frame near the contactor.
3-3. WELD OUTPUT CONNECTIONS (Figure 3-4) To obtain the full rated output from this unit, it is necessary select, install, and maintain proper welding cables. Failure in any of these areas may result in loss than to comply ' ' ' ' ' ' ' ' A B A B '~ ~ ~l to satisfactory welding performance.
4-2. OVERLOAD PROTECTION Thermostat TP1, located in the main transformer, is wired into the contactor W coil circuit. Should overheating occur, TP1 would open causing the contactor to drop out thereby suspending all operations. If TP1 opens, allow the unit to cool before resuming operations. Circuit breaker CB protects the welding power source from excessive secondary current draw. Current transformer CT1 and CT2, located in the secondary of the main transformer, sense the secondary current draw.
TROUBLE PROBABLE CAUSE No output. Thermostat TP1 open. REMEDY Allow unit a cooling period. Replace defective TP1. . Fan motor switch FMS is open. Hold START button in momentarily. Fan motor rpm is too slow due to low input Replace defective fan voltage. motor FM. Replace defective FMS. Circuit breaker CB open. Reset CB. Replace defective CB. Fuse Fl is blown. 1f it becomes necessary to replace any fuse in the welding Replace defective Fl.
