Abstract
PURPOSE: To reduce spatter and maintaing a stable short-circuit transfer type arc for a long period of time, by setting the feed speed of core wire at constant low spee and high speed in synchronism with the short-circuit period and arc period.
CONSTITUTION: An arc voltage waveform a is inputted to terminals C, E of a short-circuit detecting circuit 8 possessing a transistor 13, a Zener diode 14, and resistance elements 15W17 which are driven by DC power supply voltage Eo. The voltage of the diode 14 is selected at voltage XX' slightly larger than the short-circuit voltage at the point just before transfer from short-circuit to arc. As a result, the output between O and E, as shown in b, generates pulses of high level in the short- circuit period of the core wire 4 and the work 5, and pulses of low level in the arc period. Then, turning a selector switch 9 to A, B side, outputs Er1, Er2 are taken out, and the output Es of a comparator 12 becomes a signal proportional to Er2-ET, Er1-ET. In proportion thereto, the core wire feed motor 3 is driven, so that the core wire feed speed becomes low and high, as shown in c, respectively in the short- circuit period and arc period.
