A welding component cooling system for cooling a welding component, in particular a welding torch, includes at least one container for cooling liquid, a cooling circuit with corresponding cooling lines, at least one pump arranged in the cooling circuit for conveying the cooling liquid through the cooling lines in the cooling circuit, at least one heat exchanger arranged in a cooling line, and a device for deionizing the cooling liquid in the cooling circuit. Also a welding component, in particular a welding torch includes such a welding component cooling system. At least one sensor for measuring the conductance of the cooling liquid is arranged in the cooling circuit and is connected to a control device, wherein the control device can be connected to a welding current source connected to the welding component.

Welding component cooling system for cooling a welding component

The invention relates to a plug part () for detachable connecting a torch neck () of a water-cooled welding torch () to a socket part () arranged on a hose package (), having a cylindrical pipe element () with an axially running channel () for a welding wire () and a protective gas () and having at least two cooling channels () for supplying and returning a cooling fluid, and a union nut () rotatably arranged on the pipe element (), the union nut having an internal thread for connection to a mating external thread on the socket part (), the invention further relating to such a socket part (). In order to produce an optimal connection between the torch neck () and the hose package (), a flange () having at least one receiving opening for receiving a pin-like element () of the socket part () is arranged on the pipe element () of the plug part () in order to fix at least one angular position of the torch neck ().
