The 3M™ Speedglas™ 9100 FX Welding Helmet pfeatures a flip-up auto-darkening filter (ADF) design. It incorporates a secondary clear faceshield that's ideal for grinding and set-up work, while the ADF helps protect against the intense light of MIG, TIG, and stick applications. The integrated hard hat provides additional head protection, while side windows in the welding helmet give each welder a wider viewing field to see more of their work area.
