Abstract
The present invention provides a welding control apparatus including: a droplet separation detecting unit that detects separation of a droplet from a tip end of welding wire; and a waveform generator that alternately generates a first pulse for separating the droplet and a second pulse for shaping the droplet and outputs the generated pulse to a welding power source, the waveform generator generating a third pulse having a pulse shape different in a pulse peak current and/or a pulse width from the second pulse to output the generated third pulse to the welding pulse source after a base time of the first pulse if separation of the droplet is not detected within a peak period, a falling slope period, or a base period of the first pulse to thereby restore a droplet supply regularity.
