Description

Die Erfindung bezieht sich auf eine Einrichtung zum Steuern von Lichtbögen, insbesondeTe für Schweißautomaten, bei der die Elektrode durch einen gegebenenfalls fremderregten Vorschubmotor bewegt wird und bei der ein Widerstand im Lichtbogenkreis angeordnet ist,,--und betrifft eine Verbesserung des Gegenstandes des Patents 947 725; sie besteht darin, daß der nach dem Hauptpatent im Lichtbogenstromkreis liegende Widerstand durch die Primärwicklung eines Transformators ersetzt ist, die demnäch vom Lichtbogenstrom durchflossen wird, während die eine Seite der Sekundärwicklung an der einen Klemme des Wechselstromvorsehubmotors und die andere Seite an einer der beiden Klemmen der Primärwicklung liegt. Die andere Klemme des Vorschubmotors ist nach wie vor mit dem Abgriff des Spannungsteilers verbunden. Hierdurch wird erreicht, daß der Leistungsverlust, der durch den Ohmschen Widerstand nach dem Hauptpatent entsteht, auf ein Mindestmaß herabgesetzt wird. _ -Die Zeichnung zeigt ein Schaltungsschema nach der Erfindung.The invention relates to a device for controlling arcs, especially for automatic welding machines, in which the electrode is moved by an optionally externally excited feed motor and in which a resistor is arranged in the arc circuit, - and relates to an improvement of the subject matter of patent 947 725 ; It consists in the fact that the resistance in the arc circuit according to the main patent is replaced by the primary winding of a transformer through which the arc current flows, while one side of the secondary winding is connected to one terminal of the AC power supply motor and the other side to one of the two terminals of the Primary winding lies. The other terminal of the feed motor is still connected to the tap of the voltage divider. What is achieved hereby is that the power loss caused by the ohmic resistance according to the main patent is reduced to a minimum. The drawing shows a circuit diagram according to the invention.

Von der Stromquelle i fließt der Strom wie beim Gegenstand der Hauptpatentanmeldung über die Leitung 2, die Elektrode 3 und den Spannungsteiler 13 und dann über die Leitung 4 zurück. Die eine Klemme des Vorschubmotors 9 ist über die Leitung I I mit dem Abgriff 12 des Spannungsteilers verbunden.As in the subject of the main patent application, the current flows from the current source i via the line 2, the electrode 3 and the voltage divider 13 and then back via the line 4. One terminal of the feed motor 9 is connected to the tap 12 of the voltage divider via the line II.

Zwischen der Werkstückanflage 6 und der Leitung 4 ist die Phnnärwicklung 25 eines Transformators eingeschaltet, dessen Sekundärwicklung 26 einerseits über die Leitung io mit der anderen Klemme des Vorschubmotors 9 und andererseits mit der .einen der beiden Klemmen der Primärwicklung 2 5 verbunden isst.The parallel winding is between the workpiece contact 6 and the line 4 25 of a transformer switched on, the secondary winding 26 of which on the one hand the line io with the other terminal of the feed motor 9 and on the other hand with the .one of the two terminals of the primary winding 2 5 is connected.
