Abstract
An arc welding method alternately generates a short-circuit state and an arc state. In the method, short circuits are generated also in the arc period. This more than doubles the total number of short circuits, which is the sum of the short circuits generated in the short circuit period and those generated in the arc period. This enables a thin plate to be arc welded at a higher speed, while reducing its burn-through.
