FIELD: electricity.
SUBSTANCE: forced breakage of the welding arc on one of the electrodes used, which is melted, by turning off the current in the welding circuit of the electrode is executed. A nonconsumable electrode is used as a second electrode, while periodically changing the polarity of the products with the conservation of the polarity of each of the electrodes, connecting the product to the positive pole of the power source nonconsumable electrode connected to the negative pole of the power source. And when the product is connected to the negative pole of the power source, the melting electrode is connected to the positive pole of the source, the frequency of the polarity of the product is selected from the condition for the stability of repeated ignitions of the arc. The ratio of the duration of connection of the nonconsumable electrode to the negative pole of the power source to the cycle period is chosen in the range 0.3-0.5.
EFFECT: possibility of independent control of the productivity of the melting of the electrode and base metal.
