The neckdown detection control method for an arc welding of consumable electrode detects a necking formation of a molten drop by reaching a neckdown detection standard value V(tn) through the change of a voltage (Vw) between a molten electrode and a base metal, to make a welding current (Iw) to decrease rapidly to regenerate electric arc under a state of low current. When an advancing angle setting signal is increasing, the value of the neckdown detection standard value (Vtn) is reduced. Therefrom, it is able to detect neckdown rapidly due to higher neckdown detection sensitivity. The result is that the molten drop transition is end almost after regenerating the electric arc because the time from neckdown detection till regenerating the electric arc may be added, thus it is able to restrain sputtering, such that it is able to restrain the sputtering through detection of molten drop neckdown and rapid decrease of welding current during arc welding period. The effect of decreasing sputtering may be implemented even though the advanced angle is large.
