MIG/MAG manual welding torches are used to safely weld low and high-
alloy materials. They consist of the torch neck with equipment parts and wear
parts, handle or handle tube and cable assembly with central connector. They
conform to EN 60 974-7 and are not considered devices that independently
fulfil functions. Arc welding can only be carried out in connection with a
welding power source.
