CAUTION: Connect the input conductors to the ______ welding power the three-phase source before power supply. making connections to input conductors should be covered with an in sulating material which conforms to local electrical stan dards. Table 3-1 is provided only as a guide for selecting the proper size input conductors and fuses. The Table 3-1.
operated voltages from various line The voltages. various 61 from which this unit may be operated are stated on the nameplate and on the input voltage label. The input voltage jumper links are positioned for the I I IQI 0 voltage which is lower than the highest voltage for which the unit was designed, the jumper links will have 161 o stated on positions before operating the unit. Figure 3-3 shows the various positions of the jumper links on the standard welding power source.

SECTION 4 - OPERATION Circuit breaker CB protects the welding power source excessive secondary current draw. Current transformer CT1 and CT2, located in the secondary of the main transformer, sense the secondary current draw. Should overloading occur, CB would open caus ing the contactor to drop out thereby suspending all Circuit from Voltmeter A operations.
