Abstract: Embodiments reduce the draining of HF ignition energy via a data line for data transmission between a welding device and another part of a welding assembly. A decoupling apparatus is provided, in which a first data line portion of the data line is connected to a first coupling element and a second data line portion of the data line is connected to a second coupling element. The first coupling element and the second coupling element are interconnected via a wireless coupling path for galvanic separation of the data line, and a separate power supply is provided for each of the first coupling element and the second coupling element. The power supplies of the first coupling element and the second coupling element are decoupled from one another for a HF voltage on the data line as a result of the HF ignition voltage.
