Abstract By the use of graphite cathodes in argon the normally unstable arc root exhibiting strong vaporization of the cathode can be made stationary with a well defined, axially symmetrical vapour jet. Spectroscopic measurements of the C2 molecular bands give a vapour temperature between 4000 K and 5000 K. On strongly heated electrodes the hot plasma is to some extent hindered by the relatively cold vapour: this results in a displacement, supported by magnetic forces, of the arc root onto colder areas and thus in instability.
