ABSTRACT:
A seam welder with wire electrodes inserted between upper and lower roller electrodes to weld an overlap section of a cylinderical body formed of metal plate between the electrodes. The power supply for the welder includes a rectifying circuit for obtaining a dc voltage from an ac current source, a smoothing circuit for smoothing the dc voltage, a single converting circuit to convert the smoothed dc voltage into an alternating polarity pulse voltage, a transformer for applying this pulse voltage to the upper and lower electrodes and a capacitor connected between the primary side of the transformer and the output side of the converting circuit with a capacitance that produces resonance with the inductance of the transformer primary at the pulse voltage frequency.
