The invention relates to a wire inlet nozzle () for fastening in a coupling () of a hose package (), comprising a wire inlet element () and a fastening means () for a wire core () for guiding a welding wire (), wherein a main body is formed between the wire inlet element () and the fastening means () and a cavity () is formed in the wire inlet element (), in which cavity at least one sealing element () having an axial opening () for guiding the welding wire () is arranged. In order to prevent an escape of the protective gas in the wire inlet nozzle () in a direction opposite to the main conveying direction of the welding wire (), the main body forms a first part () of the wire inlet element (), and a second part () of the wire inlet element () can be detachably connected to the first part (), and the main body is designed as a separating plane for independently fastening the wire core () and the sealing element ().

Wire inlet nozzle

A system for mounting a wire core for a welding wire in a coupling of a hose assembly, wherein the wire core is fixed with a wire inlet nozzle in the coupling and the wire inlet nozzle is connected to the coupling by way of a mounting element which is formed in a cylindrical manner and has at least one slot to form at least two movable jaws and a wire inlet nozzle for such a mounting system are disclosed. At the end opposite from a wire inlet element, the mounting element is provided with an oval flange, which oval flange is formed in a raised manner with respect to the cylindrical region.

System for securing a wire core in a coupling and wire inlet nozzle for such a securing system

An attachment system, for attaching a gas nozzle on a gas nozzle mount arranged on a welding torch, allows detachable attachment of the gas nozzle. To create such an attachment one part of the gas nozzle mount is designed to be eccentric and for mounting a fixing element. Via an additional part of the gas nozzle mount and via at least one part of a penstock of the welding torch, a guide is formed for the gas nozzle and the gas nozzle can be secured via a rotational movement.
