cooling tubes, electrode and electrode holders for an arc plasma torch, arrays formed therein, and arc plasma torch therewith

摘要

cooling tubes, electrode and electrode holders for an arc plasma torch, arrays formed therein, and arc plasma torch therewith. The invention relates to a cooling tube (1 °) for an arc plasma torch comprising an elongate body (10.13) with an end (10.17) which may be disposed at the open end (7.12) of an electrode (7). ), and a refrigerant duct (10.15) extending therethrough, characterized in that at said end there is a thickening (10.18) similar to a protrusion of the cooling tube wall (10) pointing inwards and / or outwards , and an arrangement of a cooling tube (10) for an arc plasma torch, comprising an elongate body (10.13) with a rear end (10.14) that can be detachably connected to an electrode holder (6). an arc plasma torch, and a refrigerant duct (10.15) extending therethrough, and an electrode holder for an arc plasma torch, comprising an elongate body (10.13) with one end for receiving an electrode and a hollow interior (6.14), and characterizes This is due to the fact that at the outer surface of the cooling tube (1 °) at least one projection is provided to center the cooling tube (10) on the electrode holder (6).
