Abstract:
1. A device for the thermal coating of a surface, having: a housing; a wire supply unit mounted to the housing for guiding a wire received from a supply of a wire along a wire axis, the wire supply unit having a co-axial fixed wire guide, and an adjustable guide, wherein the free end of the wire extends beyond the adjustable guide an acts as a first electrode, a nozzle body having a plasma gas supply inlet for generating a plasma gas stream and a nozzle opening through which the plasma gas stream is conducted as a plasma gas jet aimed at and spaced from the first electrode, and a second electrode attached to the housing arranged on a longitudinal axis aligned with the plasma gas stream as it flows through the nozzle opening toward the first electrode, wherein the adjustable guide has a single degree of freedom, whereby the first electrode can be adjusted along an transverse axis generally perpendicular to both the wire axis and the longitudinal axis while maintaining a fixed spacing between the nozzle opening and the first electrode.
