摘要： A welding power control apparatus that removes the effects of shorting and noise to accurately detect droplet separation, thereby reducing spatter during droplet separation and when shorting occurs, and stabilizing welding results is achieved. Welding conditions such as welding voltage, welding current, shorting, and droplet separation are detected. Based on thus detected welding conditions, a pulse wave configuration unit generates a steady-state pulse wave and a compensation pulse wave. The steady-state pulse wave is defined by a pulse height for a pulse period and a base height lower than the first pulse height for a base period. The compensation pulse wave defined by a compensation pulse height lower than the pulse height for a compensation period followed by the pulse wave based on said detected welding conditions.

摘要： In a consumable electrode type pulsed arc welder using a CO.sub.2 shielding gas a voltage detected by a detector (13) is given to a comparator (14) to which a reference voltage of a voltage setting circuit (15) is also inputted. When the detected voltage exceeds the reference voltage, a droplet detachment detection signal is issued. Then, an output adjusting circuit (16) lowers the welder output to a level I.sub.r lower than the ordinary current I.sub.p.
