Abstract
Einrichtung mit einem Plasmabrenner mit einer in einer Aufnahme (1) gehaltenen und mit einem elektrischen Anschluß verbundenen stabförmigen, nicht verzehrenden Elektrode (3, 4), die eine mit einem Gasanschluß in Verbindung stehende Düse (9) durchsetzt. Um mit einer solchen Einrichtung rasch und sicher auch schwierige Legierungen schweißen zu können, ist vorgesehen, daß in der aus einem elektrisch nicht leitenden Material hergestellten Aufnahme (1) eine weitere stabförmige nicht verzehrende Elektrode (3, 4) vorgesehen ist, die ebenfalls eine mit einem Gasanschluß in Verbindung stehende Düse (9') durchsetzt, wobei die beiden Elektroden (3, 4) einen spitzen Winkel einschließen und jede mit einer eigenen, Gleichspannungsimpulse liefernden Spannungsquelle (31, 32) verbunden ist, deren Höhe zumindest die Brennspannung eines Lichtbogens zwischen jeweils einer Elektrode (3, 4) und einer dieser zugeordneten, mit der selben Spannungsquelle (31, 32) verbundenen Gegenelektrode übersteigt. Device with a plasma torch with a rod-shaped, non-consuming electrode (3, 4) held in a receptacle (1) and connected to an electrical connection, which passes through a nozzle (9) connected to a gas connection. In order to be able to weld difficult alloys quickly and safely with such a device, it is provided that a further rod-shaped, non-consuming electrode (3, 4) is provided in the receptacle (1), which is also made of an electrically non-conductive material a nozzle (9 ') in connection with a gas connection, the two electrodes (3, 4) enclosing an acute angle and each being connected to its own voltage source (31, 32) supplying direct voltage pulses, the height of which is at least the arc voltage of an arc between each exceeds an electrode (3, 4) and an associated counter electrode connected to the same voltage source (31, 32).
