Speedglas bringing a new standard to the marketThe innovator of the Speedglas auto-darkening welding filter completed his thesis in the shipyards of Sweden studying ways to protect Welders’ eyes and skin from from harmfull UV radiation. The studies were conducted more than 30 years ago and resulted in the first prototype of an auto-darkening welding filter, a combination of liquid crystal elements, polarizers and electronics. Today Speedglas is the worlds leading brand of protective equipment for welders and it is a vital part of the 3M’s range of protective equipment. |

In 1981 we turned the world of welding on its head by introducing the first commercially-viable auto darkening welding filter (ADF). Ever since then, the Speedglas™ brand and the technology behind it has been the standard to which others aspire.
How ADF's work? |
||||
| Before welding With the shield in the safe down position, the welder has a clear view through the welding filter. Both hands are free and the electrode can be precisely positioned. |
During welding Within 0,1 milliseconds of the arc strike, the filter has switched to the dark state. |
After welding The filter automatically returns to the clear state after welding is complete, allowing for immediate and safe inspection of the weld pool, as well as the preparation for the next weld. |
