Abstract

Inert gas welding technology with wolfram electrodes requires AC current for welding aluminium. The technology process gives special requirements to the power converter of type AC/AWI welding units suitable for welding aluminium. Namely, this requires the fast changing of the polarity of some hundred ampere DC current. The paper deals with the theoretical and experimental analysis of a circuit arrangement of a special power converter suitable for the described task. The project has been financed by the National Committee for Technical Development of Hungary.
