The Guardian front cover lens is the replaceable outer protection at the front of the helmet: it takes the spatter and dirt before they reach the auto-darkening filter (ADF). One pack contains 10 lenses. The lens fits the Guardian 50, 62 and 62F, their Air versions for powered air and the Laser Guard and Laser Guard Air.

Standards and certificates
Lens marking: EN166 1 B, meaning standard EN 166, optical class 1 and medium energy impact resistance (B). The helmet always works with both the front cover lens and the inner lens: the marked protection applies only to the complete set installed as described in the manual. Use genuine Böhler Welding lenses, as the warranty is void with other spare parts.
