Abstract

The invention relates to a wire inlet nozzle (27) for fastening in a coupling (29) of a hose package (21), comprising a wire inlet element (32) and a fastening means (31) for a wire core (26) for guiding a welding wire (9), wherein a main body is formed between the wire inlet element (32) and the fastening means (31) and a cavity (56) is formed in the wire inlet element (32), in which cavity at least one sealing element (57) having an axial opening (59) for guiding the welding wire (9) is arranged. In order to prevent an escape of the protective gas in the wire inlet nozzle (27) in a direction opposite to the main conveying direction of the welding wire (9), the main body forms a first part (54) of the wire inlet element (32), and a second part (55) of the wire inlet element (32) can be detachably connected to the first part (54), and the main body is designed as a separating plane for independently fastening the wire core (26) and the sealing element (57).

Description

technical field [0001] The invention relates to a wire inlet nozzle for fastening in a coupling of a hose assembly, comprising a wire inlet element and a wire core for guiding the welding wire, wherein between the wire inlet element and the fastening A body is formed between the devices 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. Background technique [0002] Generally, wire inlet nozzles are used to introduce welding wire into a hose assembly that connects to a welding torch. Additionally, shielding gas, welding current, control lines and coolant are delivered to the torch via hose assemblies. In order to obtain the required weld seam quality, the protective gas must surround the welding wire at the welding station at the latest. In many cases, the protective gas is already supplied to the cable core in the region of the wire inlet nozzle, in which the weld...
