Abstract (en)
[origin: WO2022233484A1] The invention relates to a combined extraction/shielding gas nozzle (10) of an arc welding torch with a consumable electrode with a shielding gas channel (1) for supplying shielding gas to the welding process, and an extraction device (3) with at least one extraction channel (6) with an extraction opening (7) for extracting the flue gas produced during the welding process. According to the invention, the shielding gas channel (1) and the at least one extraction channel (6) are disposed radially and offset to one another in the axial direction such that the extraction opening (7) for the at least one extraction channel (6) lies behind the shielding gas channel (1) in the direction of flow of the flue gas.
