Abstract: A plasma electrode for a plasma cutting device consisting of a hollow cylindrical electrode body at whose front side a centric core holder directed in the interior of the electrode, arranged on the front side for the mounting of an emitting electrode core is arranged, wherein in the interior of the electrode body a cooling tube is arranged, through which an axial coolant flow flows, characterized in that the cooling tube is held position secured at least partially with its face on the core holder.
Abstract: This application relates to a nozzle (3) for a liquid-cooled plasma cutting torch, having at least one groove (6a) which is arranged on an outer wall (4) of the nozzle (3) with which the liquid makes contact, is oriented with the direction of its longitudinal axis (18) approximately perpendicular to the nozzle mid-axis (17) of the nozzle (3) and reduces the wall thickness (15) of the nozzle (3), at least in this region, and has a groove base (12, 13) that reaches into the wall thickness (15), wherein the groove base (12, 13) of the groove (6a) is formed so as to be approximately parallel to the contour of the inner wall (5) of the nozzle (3).
