Method for soldering work pieces

Method of brazing workpieces with a torch, in particular a plasma or welding torch, having an electrode, in which a transmitted and/or non-transmitted working arc, supplied with power from a power source or a current source, is produced in order to generate a plasma beam from a delivered plasma gas, whereby at least one filler material is fed to the seam region of the workpieces to be joined, characterized in that the filler material (38) is connected to the or to another power source or current source (2, 39) in such a way that one potential (34, 35, 40, 41) of the power source or current source (2, 39) is applied to the filler material (38) and the other potential (34, 35, 40, 41) to the workpieces (16), and the power source or current source (2, 39), in particular the power delivered by the power source or current source (2, 39), is regulated in such a way that when the filler material (38) is lifted off the workpiece (16) an arc is prevented from being struck.
