Our welding helmet is combined with a (170 mm x 100 mm) clear, protective visor and comes with the 3M™ Speedglas™ Welding Filter 9100XXi. 3M™ Speedglas™ Welding Filter 9100 Series continues our tradition of outstanding optical quality, including uniform shading and minimal distortion across the entire filter viewing area. The 9100XXi filter features our new optical solution which makes the filter view seem lighter, more detailed and colourful. This provides better control of your weld puddle and a clearer view of coloured welding machine controls. It has automatic ON/OFF controls. The filter has seven variable dark shades (5, 8 and 9-13) for most types of arc welding and a viewing area of 73 mm x 107 mm and is made for the professional welder. A 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. The welding helmet 9100 FX is designed with comfort in mind with an ergonomically designed head suspension. It has a wider field of view thanks to the shade 5 filter side windows and the welding filter has a tack welding comfort mode designed to help minimise eye strain during extended tack welding applications. It's compatible with most 3M™ Safety Spectacles and 3M™ Disposable or Reusable Welding Particulate Respirator.
