Abstract

PURPOSE: To obtain arcs continuously without adding any special apparatus, by supplying an AC power while a phase difference is given to nonconsumable and consumable electrodes, the number of which is more than one, and by installing the electrodes so that they are close to each other.
CONSTITUTION: An nonconsumable electrode A is connected to the secondary side of a welding transformer 2 whose primary side is connected to the V and W phases of a three-phase AC power source. On the other hand, a consumable electrode A is connected to a welding transformer 3 whose primary side is connected to the U and V phases of a three-phase AC power source. Therefore, the electric current of the electrode B is delayed in the phase by 60° than that of the electrode A, and at the point (a) on the electric current waveform an electric current a-b flows into the electrode B and normal arcs are generated. Therefore, when both electrodes are installed closely to each other in accordance with the phase difference and the current value of each electric current, the electrode A can easily be reignited because the electrode A is triggered by the arc of the electrode B. Similarly, the electrode B can easily be reignited at the point (b') by the arc of the electrode A.
