Abstract
En krets (12) for tilbaketrekning av en bue til bruk i et plasmabuesystem med en brenner (10) har en elektrode (32) og et munnstykke (34), en strømkilde (20) for likestrøm, en effektkrets (100-150) for kobling av strømkilden (20) over elektroden (32) og et arbeidsstykke (40) som skal skjæres, en effektbryter (70) for kobling av munnstykket (34) til strømkilden (20) når bryteren en sluttet for dannelse av en tennstrømtilstand i driften og for kobling av munnstykket (34) fra arbeidsstykket (40) når den er brutt for dannelse av en skjaeretilstand i driften, en forsterkeranordning (100) for regulering av strømkilden (20) til en første innstilt strøm når den er i tennbuetilstand og en andre innstilt strøm når den er i skjæretilstand og en tilbaketrekningskrets (70) for buen for veksling av effektbryteren (72) fra å være brutt til å være sluttet, hvilken tilbaketrekningskrets for buen innbefatter strømmålende anordninger (60, 62) til frembringelse av et første signal som representerer den virkelige strøm som tilføres fra strømkilden (20) til effektkretsen, anordninger til frembringelse av et andre signal som representerer et strømnivå under den andre innstilte strøm og anordninger for slutning av effektbrytere når det første signal er stort sett lik det andre signal.
