Device and method for welding a workpiece () having a welding torch () which can be mechanically coupled by a coupling element () to a hose bundle () for supplying the welding torch () at least with compressed air or with a protective gas, wherein compressed air applied to the coupling element () can be diverted by a diverting valve () provided in the coupling element () for actuating an actuator ().

Coupling structure and method for feeding compressed air to welding device using same

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 ().
