3M Speedglas Auto-darkening Welding Filter
For an auto-darkening filter with seven variable dark shades (5, 8 and 9-13) for most types of arc welding, get 3M Speedglas Auto-darkening Filter 9100X, 500015. It has a viewing area of 54 mm x 107 mm and is made for the professional welder. Our 3M Speedglas Welding Filter 9100 Series features uniform shading and minimal distortion across the entire filter viewing area. The delay function sets the dark-to-light opening time, and it’s possible to lock-in any shade, e.g. in light state 3 when grinding. It has a switching time (light-dark) of 0.1 ms, and the sensitivity of the arc detection can be adjusted for reliable switching. Tack welding comfort mode also helps minimise eye strain during extended tack welding applications.
