The viewing angle plays an essential role in the welding helmet. Welders prefer welding helmets which are wide-angled. It is a crucial element for working in complicated places.
The 3M Speedglas has an auto-darkening feature which enhances the viewing area with three arc sensing units. It enhances the clarity of the viewer by ten times hence resulting in improving the accuracy of vision. “Accuracy of Vision” is a term that means lens adjusting light levels.
It has three arc sensors which offer effective detection of for when an arc is selected which instantly begins the light-to-dark shift finishing it in approximately 0.1 ms. When the helmet needs to switch from dark-to-light shade, it takes 40-250 ms.
Take an example of our eyes, when we go to a darker place such as cinema, it adjusts according to the light. The same way, when we come out, our eyes adjust according to the light entering the lens. The lens of the 3M Speedglas welding helmet works in the same way.
In this way, the wielder can concentrate on the work. He does not need to manually adjust the light anymore, all thanks to 3M auto-darkening feature.
