A consumable electrode arc welding method includes: setting an optimal voltage and an increasing slope of a short circuit current to correspond to a setting current; feeding a consumable electrode wire; and alternately generating a short circuit condition and an arc condition, thereby carrying out welding, wherein the short circuit current is controlled by changing the increasing slope of the short circuit current according to a difference between the setting voltage and the optimal voltage when the setting voltage is different from the optimal voltage. With this, the increasing slope of the short circuit current and the current value corresponding to the inflection point of the short circuit current are automatically changed. |
