Combined Extraction/Shielding Gas Nozzle of an Arc Welding Torch with a Consumable Electrode and Torch Neck Having a Combined Extraction/Shielding Gas Nozzle

A combined extraction/shielding gas nozzle (10) of an arc welding torch with a consumable electrode, comprising:

• a shielding gas channel (1) for supplying shielding gas to a welding process;
• 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, wherein 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,
• a threaded insert (12) for screwing onto a torch neck (13) of a welding torch (15);
• and
• an electrical insulation (20) between the threaded insert (12) and the extraction device (3).
