In order to easily regulate the supply of welding wire to the welding point during a welding process, the electrical potential produced by the welding current around the electrode is tapped with the welding wire and the control of the welding wire feed speed is carried out on the basis of the tapped potential and this control results in an average welding wire feed speed being established.

Welding device and welding method with self-setting welding wire feed speed

Burner for a welding apparatus having a non-melting electrode, a wire feed device for a welding wire and a power feed device for introducing an electric heating current into the welding wire that is supplied. The wire feed device can be activated in two directions of advance and an electric voltage applied by the power feed device to the welding wire can be regulated to ignite an igniting arc between the tip of the welding wire and the workpiece.
