Flammenbogen.Flame arc.
In der Patentschrift 210251 ist eine Kathode für Bogenlampen beschrieben, die aus einem dünnen Kohlekern mit festem Metallmantel besteht. Diese Kathode ist für Bogenlampen hoher Stromstärke bestimmt und hierfür dadurch besonders geeignet, daß ihr Querschnitt infolge des gutleitenden Metallmantels verhältnismäßig gering ist. Sie spitzt sich beim Abbrennen sehr stark zu, so daß der Lichtbogen sehr konzentriert und stabil wird und keine Neigung hat, zu wandern, wie dies bei gewöhnlichen Kathoden ohne Metallmantel mit einem der Stromstärke entsprechenden Querschnitt der Fall ist.In the 210251 patent is a cathode described for arc lamps, which consist of a thin carbon core with a solid metal jacket consists. This cathode is intended for and for high amperage arc lamps particularly suitable because their cross-section due to the highly conductive metal jacket is relatively low. It comes to a very sharp point when it burns, so that the Arc becomes very concentrated and stable and has no tendency to wander like this in the case of ordinary cathodes without a metal jacket, with one corresponding to the current strength Cross-section is the case.
Diese Eigenschaften machen diese Kathode zum Schneiden, Schweißen und Löten von Metall durch den elektrischen Flammenbogen sehr geeignet. Diese Vorgänge setzen eine hohe Stromstärke voraus, so daß also dabei die Verhältnisse im Flammenbogen ungefähr 25 These properties make this cathode very suitable for cutting, welding and soldering metal through the electric flame arc. These processes require a high current intensity, so that the conditions in the flame arc are approximately 25
dieselben sind wie im Lichtbogen von Lampen hoher Stromstärke. Da durch die dünne, sich sehr zuspitzende Kathode der Flammenbogen sehr stabil wird, läßt sich beispielsweise das Schneiden oder Ausschneiden von Platten sehr genau vornehmen.are the same as in the arc of high amperage lamps. Because through the thin, very tapering cathode of the flame arc is very stable, for example Carry out cutting or cutting out of panels very precisely.
Die Ausführung des Verfahrens geschieht in bekannter Weise derart, daß das zu schneidende oder lötende Metallstück als Anode und der dünne Kohlestab mit Metallmantel als Kathode in den Stromkreis eingeschaltet wird.The method is carried out in a known manner in such a way that the to be cut or a piece of soldering metal as an anode and the thin carbon rod with a metal jacket as a cathode connected to the circuit will.
