What is Auto Darkening?
Safety products that increase your performance
The key to remember with 3M™ Speedglas™ auto-darkening welding lenses (or ADLs) is consistency:
They enable constant, comfortable vision to welders. They provide constant protection from ultraviolet and infrared (UV/IR) radiation. They consistently auto-switch from clear to dark, and back again, in just the way the welder wants.
Awkward made easier
Auto-darkening welding lenses also eliminate the neck-strain of “helmet flipping” while greatly increasing the accuracy of electrode placement. This, in turn, reduces the need for grinding and rework.
In addition, welders can get into tight, cramped spaces with their eye and face protection already in place. Their constant, clear view makes even extremely awkward welds a lot easier.
Meets or exceeds all applicable safety standards
All Speedglas™ welding lenses conform to Australian Standard AS/NZS1337 and AS/NZS1338.1 for eye protection for welders, as well as all relevant international standards.
Optional Extended 3 Year Warranty available on all Auto-Darkening Lenses
How Speedglas ADLs work
Each Speedglas welding lens is a laminate of seven different layers: a UV/IR filter, three polarizers and three liquid crystal elements. The UV/IR filter continually blocks harmful radiation, whether the filter cassette is ON, OFF, light or dark.
Aided by surface-mounted electronics, the proprietary liquid crystal elements act as shutters that detect and react to the welding arc by instantly becoming either dark or light, as needed.
The level of protection from the UV/IR filter is constant; it equals a shade 13 traditional (non-auto-darkening) welding lens.
