Abstract
An arc welding control method is for performing control in an arc period. The control includes: (i) increasing a welding current to a first current value at a first gradient and maintaining the welding current at the first current value for a first period; (ii) reducing the welding current from the first current value to a second current value at a second gradient and maintaining the welding current at the second current value for a second period; (iii) increasing the welding current from the second current value to a third current value at a third gradient; and (iv) starting to reduce the welding current from the third current value within a third period, which is shorter than the first period, after the welding current reaches the third current value.
