Abstract
An arc welding control method includes: feeding a welding wire; and repeating a short-circuit period and an arc period, where the arc period includes a first arc period and a second arc period following the first arc period. A welding current is applied using constant current control during the first arc period, and the welding current is applied using constant voltage control during the second arc period. The first arc period is set to an electrode-negative polarity, and a period other than the first arc period is set to an electrode-positive polarity.
Claims5
An arc welding control method comprising:
- feeding a welding wire;
- and
- repeating a short-circuit period and an arc period, the arc period comprising a first arc period and a second arc period following the first arc period,
- wherein a welding current is applied using constant current control during the first arc period,
- the welding current is applied using constant voltage control during the second arc period, and
