Claim 0:
1. A welding method using a welding torch having an electrode and using a welding wire that is supplied to a welding point at a welding wire feed speed, said welding method comprising:
creating an arc to be maintained between the electrode and a workpiece to be welded by way of a welding current flowing through the electrode, said welding current producing a distribution of an electrical potential in the vicinity of the electrode;
tapping the electrical potential in the vicinity of the electrode with the welding wire;
controlling the feed speed of the welding wire according to a tapped electrical potential, said controlling resulting in establishing an average welding feed speed; and
applying, before welding an electrical voltage to the welding wire to detect the electric voltage as the electrical potential before ignition of the arc and to determine a position of the welding wire in relation to the workpiece from the detected electrical potential before the ignition of the arc.
