摘要

The object of the invention is a method and an arrangement in a gas shielded arc welding device, such as a MIG/MAG-welder, for reducing the sticking of the wire electrode (1) to the welding current tip (3) of the welding torch (2) in connection with the termination of a welding step. The method utilizes a gas shielded arc welding device comprising a welding torch (2), a power source (4), wire feeding means (5), and a control means (7) for controlling at least the power source (4) and the wire feeding means (5). In connection with the termination of a welding step, a step of switching off the welding current is performed, wherein the welding current is switched off and the electric arc, as a consequence of the welding current being switched off, is extinguished, and a step of stopping the wire feeding is performed, wherein the wire feeding is stopped. After the performing of the step of switching off the welding current and the step of stopping the wire feeding, a step of post stop feeding is performed, wherein the wire electrode (1), by means of the wire feeding means (5), is being moved in relation to the welding current tip (3) of the welding torch (2).
