The 3M™ Versaflo™ Respiratory Helmet Assembly M 407SG, M Series Welding Shield includes a flame resistant shroud and is designed to help protect the user from certain airborne contaminants, and certain head, eye, face, and welding hazards. It has a lower weight and larger viewing area than the L 905SG, and is suitable for most operations commonly associated with plasma cutting, grinding, MIG, TIG, and GMAW welding. It can be combined with the 3M™ Versaflo TR 600 PAPR or 3M™ Speedglas™ Adflo PAPR and cartridges to build a complete welding system.
