Abstract
In a method and device for performing welding, after the welding current reaches a first current value during a short circuit, the feeding of the welding wire is stopped, slowed down, or moved backward. As a result, the opening of a short circuit is urged to reduce the frequency at which welding is unnecessarily interrupted by an overcurrent protection function. This achieves high weld quality such as the absence of welding defects, and high production efficiency.
