What determines the correct shade of lens during welding?
The Amperage Level
You will need to use a lens that is darker the higher the amperage. Due to using a higher amperage to weld, the darker lens will have the ability to filter out more harmful radiation light. Lighter shade lenses are appropriate for low-amperage light welding.

Why should shaded lenses be covered with clear plastic lenses?
Any broken pieces of the filter lens are kept out of the eye by a clear plastic retainer lens. The lens is shielded from jarring temperature changes that could cause it to break by a gasket made of heat-insulating material that sits between the cover lens and the filter lens.
