ALTERNATING-CURRENT WELDING METHOD AND ALTERNATING-CURRENT WELDING DEVICE

If arc interruption occurs during AC arc welding, a first AC frequency predetermined for normal welding is switched to a second AC frequency higher than the first AC frequency. This allows the arc to be reignited without applying a high frequency high voltage, thereby preventing the damage of the su...

More Information
Summary:If arc interruption occurs during AC arc welding, a first AC frequency predetermined for normal welding is switched to a second AC frequency higher than the first AC frequency. This allows the arc to be reignited without applying a high frequency high voltage, thereby preventing the damage of the surface of the weld bead or communication failure due to the high frequency high voltage.
