Protection from light radiation is directly related to filter lens density. More sensors mean better coverage, especially for out-of-position welding where a sensor could be obstructed. A longer delay time is helpful when welding at very high amperages, since molten metal may still emit harmful rays until it cools. Welding Lens Shade Numbers One of the first things to look at when buying a welding lens is its shade number.
