Abstract
A method of controlling arc welding with a consumable electrode includes repeating the following periods in sequence: a short-circuit welding period to perform short-circuit arc welding; a pulse welding period to perform pulse welding; and a cooling period in which the welding current output is zero.

A method of controlling arc welding with a consumable electrode, the method comprising:
- repeating following periods in sequence:
- a short-circuit welding period to perform short-circuit arc welding;
- a pulse welding period to perform pulse welding;
- and
- a cooling period in which a welding current output is zero,
- wherein the pulse welding period starts periodically at a constant interval by adjusting a length of the short-circuit welding period in accordance with a length of time from when feeding of a welding wire as the consumable electrode starts until when a short circuit is detected in the short-circuit welding period.

A method of controlling arc welding with a consumable electrode, the method comprising:
- repeating following periods in sequence:
- a short-circuit welding period to perform short-circuit arc welding;
- a pulse welding period to perform pulse welding;
- and
- a cooling period in which a welding current output is zero,
- wherein
- the method further comprises a second short-circuit welding period between the pulse welding period and the cooling period,
- in the second short-circuit welding period, a welding wire is short-circuited to an object to be welded, and
- a length of the second short-circuit welding period is adjusted in accordance with a length of time from when feeding of the welding wire as the consumable electrode starts until when a short circuit is detected in the short-circuit welding period so that the pulse welding period starts periodically at a constant interval.
