The method according to claim 1, characterized in that the width of the rectangular pulses of "positive polarity" from the product to the electrode is less than the width of the pulses of "negative polarity" from the electrode to the product. ! 3. A device for implementing the method is a power source connected at the first input to a power source, and at the output to a welding circuit including two welding electrodes and a welded product, characterized in that the power source is made of three inverters included according to the "triangle" scheme, which are controlled by the control unit. ! 4. The device according to claim 3, characterized in that each inverter generates rectangular pulses of current, adjustable frequency. ! 5. The device according to claim 3, characterized in that each inverter is turned off and on at the right time and gives a pulse of the required polarity.
