Abstract

invention concerns a wear part for electric-arc welding torch, produced in a copper alloy containing principally copper and, in addition, one or several alloy metals selected among tellurium, sulphur, lead, chromium and zirconium. Preferably, the alloy material content ranges between 0.01 % and 5 % and the copper content is at least 90 % to 95 %. The inventive wear part can be a whole or part of an electrode, a nozzle, a cartridge consisting of a nozzle/electrode assembly, an electrode holder and an electrode holder seat. The invention also concerns a plasma torch provided with one or several said wear parts and its use in a plasma cutting operation as well as a TIG, MIG or MAG torch provided with one or several said wear parts and its use in a welding operation.
