Abstract

The invention relates to a protection device for protective gas welding torch, comprising a nozzle pipe (D), a gas jet (17) for the introduction of protective gas to the welded joint and a flow nozzle (13) or contact nozzle for flow transfer and guidance of an electrode wire (E) within an introduction channel (3), terminating in a front face (14). In order to achieve a continuous run for the welding process in a simple and effective manner and to prevent damage or detrimental effects to the gas nozzle and flow nozzle by welding spatter causing interruptions to a continuous welding process, the gas nozzle is provided at the conical embodiment of the outlet end (18) with a device (19) shielding the outlet from welding spatter. Said device has preferably a disc- or plate-like form with through openings (21, 20) for the gas flow and the electrode wire or in the form of a conical plug with through openings, or coated in the critical positions with a coating of a material resistant to welding beads.
