  • Patent number: 10850340
    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.

  • Patent number: 8502114
    Abstract: An AC pulse arc welding method of the present invention sets an appropriate AC frequency based on a wire feed rate and a polarity ratio when the polarity ratio is changed without changing the wire feed rate to control a heat input to a base material, and sets an appropriate straight polarity current value necessary for one drop per pulse from the polarity ratio and the AC frequency in AC pulse welding. The method makes it possible to achieve appropriate AC pulse welding by setting the polarity ratio, and to easily set the welding conditions.
