Abstract

The present invention relates to plasma torches and, in particular, to a method of improving the service life of electrodes, especially stub-ended electrodes. An electrode for a plasma torch comprises an electrode body and an electrode tip, wherein the electrode tip is fusion welded either directly or indirectly to the electrode body.
