The invention relates to a device for buffering a welding wire, whereby a wire buffer, in particular a wire buffer magazine is arranged between a wire advance device and a further wire advance device which is preferably arranged in the vicinity of a welding torch, or in the welding torch and the welding wire is run between the two wire advance devices in a wire core. According to the invention, a simple and compact a buffer device as possible and an improvement in the dynamic behaviour of the wire supply can be achieved, whereby the wire core is attached or fixed at one end and the other end thereof is free to move and the wire core with the welding wire is arranged such as to be free to move within a wire guide tube with a substantially larger cross-section than the outer diameter of the wire core and the buffer volume of the wire buffer magazine is defined by the cross-section and the length of the substantially larger wire guide tube.
A buffer device for a welding wire, wherein a wire buffer, in particular a wire buffer storage, is arranged between a wire feeder provided on the welding apparatus, or an external wire feeding means, and a further wire feeder preferably arranged in the region of a welding torch, or within the welding torch, and the welding wire is conducted between the two wire feeders within a wire core, wherein the wire buffer storage (35) is designed in a manner that the wire core (30) is fastened or fixed on one end, with its other end being freely movable, wherein the wire core (30) together with the welding wire (13), at least over a partial region, is arranged to be freely movable within a wire guide hose (38) having a substantially larger cross section (39) or inner diameter than the cross section or outer diameter (33) of the wire core (30), and that wherein the storage volume of the wire buffer storage (35) is defined by the cross section (39) and length of the substantially larger wire guide hose (38).
A welding plant including a welding apparatus, a hose package and a welding torch, wherein the hose package connects the welding torch with the welding apparatus, and a device designed as a wire buffer storage and arranged between two wire feeders, wherein said device or wire buffer storage (35) is formed in or around the hose package (23).
