The invention relates to a supply pipe arrangement (24) with a supply pipe (21) for a welding device and for connecting to a robot wrist joint (17). The supply pipe has a guide channel (26) for taking up and guiding a welding wire and an electrical conductor arrangement (41), which is covered by insulation. The supply pipe arrangement has a coupling device (22) for rotatably connecting the supply pipe to a wire-supplying device (23). The coupling device has a plug part, which is formed by a connecting piece (45) and is taken up rotatably in a stationary socket part for connection with the wire-supplying device. A channel wall (33) of the guiding channel has a torsion-resistant supporting structure. |
