Abstract

Høyfrekvens kraftforsyning (10) for å levere en sveisestrøm gjennom en drossel (80) til en svelsestasjon (W) som Innbefatter et elektrodeelement (70) og et arbeldsstykkeelement (72), der kraftforsyningen Innbefatter en transformatorinnretning (20) for å skape en første strømpuls l en første sekundærvikllng (42) og en andre strømpuls i en andre sekundærvikling (44) og middel (50, 56, 60, 62) for å koble nevnte sekundærvik- linger (42, 44) til å føre nevnte strømpulser gjennom nevnte drossel og over nevnte elementer. Transformator- innretning Innbefatter en første transformator (A) med en første kjerne (Cl) og middel for å motta på den første kjernen den første sekundærviklingen (42) med den første kjernen magnetisert i en første primær fluksretning ved dannelse av den første inngangspulsen, idet en andre transformator (B) med en andre kjerne (C2) og middel for å motta på den andre kjernen den andre sekundærviklingen (44) med den andre kjernen magnetisert l en andre primær fluksretning ved dannelse av den andre inngangspulsen og kjernetilbakestill- ingsmiddel (220) for å magnetisere en av kjernene i fluksretningen som er motsatt den primære fluksret- ningen når nevnte andre kjerne magnetiseres i sin primærretning.
