Speedglas improves upon what the welder sees

  • Your goal is to weld great welds, consistently. Our goal is to provide you consistently clear, comfortable vision – with full-time eye and face protection. Because we make many of our own welding filter components, we can readily test and transfer new technologies. Safety is the prime consideration when it comes to welding PPE. But the 3M Speedglas optics team aims to help welders even more by continuously improving the optical experience of our welding filters.

How to select a welding filter

What does your welding process require from your filter?


Still seeing green?

Still Seeing Green - comparison image
  • See the difference!

    Imagine what more realistic-looking colors and details could do for you:
     

    • Provide better control of your weld puddle – with a view that appears lighter, brighter, and more realistic.
    • Help you focus on your welding set-up, welding technique, and inspection of just-completed welds.
    • Give you a clearer view of colored welding machine controls – even with your helmet in the safe, down position.   
  • We’ve enriched your color range!

    Compare the light transmittance levels between our Natural Color Technology ADFs and our other filters. Note that the Natural Color filters transmit a much higher percentage of colors like blues and reds, while reducing the greens. And, as always, harmful UV and IR radiation is blocked in all of our filters. ON or OFF.

The 3M™ Speedglas™ Welding Filter Series 9100 continues our tradition of outstanding optical quality, including uniform shading and minimal distortion across the entire filter viewing area.
