The world’s first curved auto-darkening filter.
This is a helmet for welders doing high-performance, critical work.
We gave professional TIG welders prototypes of helmets with diﬀerent lens sizes. Their favourite lens size was the curved, 2-to-1 aspect ratio we used for designing the G5-02 auto-darkening filter (ADF). A wider view was much higher rated than a taller view.
And the only way to get wider views without making the helmet wider is by inventing a curved ﬁlter.
