Abstract
PURPOSE: To prevent the fluctuation in arc length and make globule migration correct by providing circuits which fractionate welding current, determine the integrated value for one pulse period, compare the same with a set value and regulate pulse frequency.
CONSTITUTION: The set quantity of a wire feed speed command circuit 1 is put into a function generator 4 which determines the area of a pulse current waveform corresponding to the feed rate and inputs the same to a comparator 5. The welding current from a detecting circuit is amplified 11, and is separated to the current in a base priod and the current in a pulse period by a selecting circuit 12. The peak value of this pulse current is compared with the set value of a peak current command circuit 13 in a comparator 14. The differential signal thereof is inputted to a peak current value setting circuit 15, which controls the peak current value constant. At the same time, the separated pulse current is integrated to the current value of one pulse period in an integrating circuit 6, the output whereof is compared with the integrated value from the function generator 4 in the comparator 5. The differential signal thereof is put into a pulse frequency setting circuit 9 which compares the same with the pulse frequency signal corresponding to the wire feed and decreases the pulse frequency.
