3M 49958 Speedglas 100 Xterminator Auto-Darkening Welding Helmet with ADF 100V, Shade 8-12

The 3M Speedglas 100 Xterminator is a fully assembled, ready-to-use auto-darkening welding helmet featuring a bold floating skull graphic design. Built on the trusted Speedglas 100 platform, it delivers excellent optical quality, fast arc detection, and reliable light-to-dark switching — making it well-suited for Stick (MMA), MIG/MAG, and most TIG welding applications.

The included Speedglas 100V Auto-Darkening Filter (ADF) darkens to the selected shade in just 0.1 milliseconds upon detecting a welding arc, and provides permanent UV/IR protection at shade 12 — even in the light state. The light state is shade 3, giving a clear view of the work area when no arc is present.
