Abstract
The invention relates to a method of feeding welding wire (13) from a wire supply reel (14) to a welding torch (10), having at least one welding wire feeder (27) and an apparatus, in particular another welding wire feeder (28), for applying a feed force, in particular a main drive (29) and an auxiliary drive (30), whereby a feed force or a pressure force, acting on the welding wire (13) between the welding wire feeders (27, 28) is detected by a detection means, in particular a sensor, and compensated or limited. A deflection or lateral deflection of the welding wire (13) is detected on the basis of the feed force or pressure force on the welding wire (13) between the welding wire feeders (27, 28), in particular the main drive (29) and the auxiliary drive (30), and this deflection is used as information for regulating at least one of the welding wire feeders (27, 28).
