Abstract

The electric energy source for a resistance-welder comprises a static reversing device, a welding transformer, and a first static frequency converter (10) comprised of semiconductor elements, of which the output alternating voltage has a frequency and a pulse wave-form different from the frequency and the pulse wave-form of the supply voltage provided to the reversing device. In order to vary on a large range the pulse wave-form, the amplitude and the pulse ratio, the source comprises at least a second frequency converter (11) mounted in parallel on the first frequency converter (10) and of which the output alternating voltage may be added, in phase synchronism, to the output alternating voltage of the first frequency converter (10) in the primary circuit of the welding transformer (12).
