ArcOne's Optiva variable shade auto-darkening welding helmets have a variable shade 9-13 with a light state of 4. A potentiometer on the outside of the helmet allows customized shade selection without the need to remove the helmet or gloves minimizing down time. UV/IR protection up to shade 16 in both the light and dark state and solar powered so there are never any batteries to change. Perfect for all welding applications.
Enough room for a respirator.
