Abstract: Plasma electrode (1) for a plasma arc torch consisting of an electrode body, at least one electrode core (4) disposed on the electrode tip, wherein the plasma electrode (1) is constructed in at least two parts and consists of the electrode tip (2) and an electrode part (3), and out of the electrode tip (2) and a electrode part (3) consists, and that the electrode tip (2) is held replaceably on the electrode part (3).

Abstract: The invention relates to a cooling pipe for a plasma arc torch, comprising a hollow cylindrical electrode body having a central internal core, at the front end of which an electrode core holder having an electrode core inserted therein is arranged, and a hollow cylindrical cooling pipe which is inserted into the internal bore in a sealing manner and which features an internal bore that form a cooling channel as a feed and, in the intermediate space between the outer circumference of the internal bore and the inner circumference of the electrode body, forms a cooling channel formed as a return, wherein the cooling pipe has, on the inner side thereof that is facing the electrode core holder, space-maintaining means (e.g. a spacer washer or wires or rods), which are suitable to rest on the front end of the electrode core holder.

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).
