Welding fumes are composed of metals and most fumes contain a small percentage of manganese. Manganese may be found in carbon steel shielded metal arc welding (SMAW or stick) electrodes as part of the flux coating on the welding rod, as a flux in carbon steel flux core arc welding (FCAW) and as a filler metal in gas metal arc welding (GMAW or MIG) wire. It is present in recycled carbon steel and used in abrasion resistant applications such as ball mills or earth moving equipment. Manganese has a substantially lower boiling point than iron, therefore, it will vapourize more easily than iron leading to a higher presence on a percentage basis in welding fumes than in the original wire."}
