A welding head for a welding device is operable to weld a component which is not rotationally symmetrical onto a workpiece. A head attachment includes a holding device for holding the component and to carry a welding current to the component. A mouthpiece is arranged around the holding device and the component during a welding operation. The holding device and the mouthpiece move in relation to each other along a welding axis. The mouthpiece contacts the workpiece and provides a protective gas tangentially about the welding component. An interface device supplies the welding current to the holding device. A connecting device mechanically connects the holding device to the interface device. The connecting device is subdivided into a first connection piece connected to the holding device and a second connection piece electrically insulated from the first connection piece.
