 gegensinnig gerichtete und in Serie geschaltete Steuerwicklungen 10 und 11,-welche beispielsweise vom Kollektorstrom eines Transistors durchflossen sein können. Die Arbeitswicklung 9 liegt vorzugsweise in Serie mit der Feldwicklung des Generators 2. Beim Auftreten einer Spannungsspitze an der Arbeitswicklung 9 wird in beiden Steuerwicklungen 10 und 11 gleichzeitig eine Sekundärspannung induziert, welche wegen des gegensinnigen Windungssinnes der Spulen 10 und 11 kompensiert wird. Der die Wicklungen 10 und 11 speisende Transistor kann infolgedessen nicht beschädigt werden. 



   Der Transduktor kann nach einem   abgewandelten Ausführungsbeispiel   auch aus zwei einfachen Schenkelkernen mit je einer Arbeit-un einer Steuerwicklung bestehen. Der Stromfluss durch die Arbeitswicklungen erfolgt hiebei über vorgeschaltete Gleichrichter im Halbwellenbetrieb.

 Control windings 10 and 11, which are directed in opposite directions and connected in series, through which, for example, the collector current of a transistor can flow. The working winding 9 is preferably in series with the field winding of the generator 2. When a voltage peak occurs on the working winding 9, a secondary voltage is induced in both control windings 10 and 11 at the same time, which is compensated for because the coils 10 and 11 are turned in opposite directions. The transistor feeding the windings 10 and 11 cannot be damaged as a result.



   According to a modified embodiment, the transducer can also consist of two simple leg cores, each with a work and a control winding. The current flow through the working windings takes place via upstream rectifiers in half-wave operation.

Claims (1)

PATENTANSPRUCH : Regelanordnung zum Lichtbogenschweissen nach Patent Nr. 218636, dadurch gekennzeichnet, dass im Falle die am Ausgang des Regelverstärkers erscheinende Stellgrösse auf die Feldwicklung eines Schweissgenerators einwirkt, der in den Regelverstärker (4) aufgenommene Transduktor (Fig. 2) in an sich bekannter Weise zwei Steuerwicklungen (10,11) aufweist, die derart bemessen und hintereinandergeschaltet sind, dass in ihnen induzierte Spannungen, die von Flussänderungen der Arbeitswicklung (9) herrühren, sich gegenseitig aufheben. PATENT CLAIM: Control arrangement for arc welding according to patent no.218636, characterized in that in the event that the manipulated variable appearing at the output of the control amplifier acts on the field winding of a welding generator, the transducer (Fig. 2) accommodated in the control amplifier (4) has two control windings in a manner known per se (10, 11) which are dimensioned and connected in series in such a way that voltages induced in them, which result from changes in the flux of the working winding (9), cancel each other out.
