Abstract
A welding control apparatus includes an integrator for starting calculation of a voltage error integral value Svwhen a first pulse period ends and a second pulse period starts in a pulse cycle, based on various data. The apparatus also includes a comparator for comparatively determining whether a value of the voltage error integral value Svprovided as the calculation result has become 0, and a waveform generator for terminating the relevant pulse cycle and starting a next pulse cycle when the value of the voltage error integral value Svis 0. Where2=∫{(2−2)+2−2}  (1).
