Advantages
The shade level of a welding lens refers to its ability to filter out specific amounts of light. The higher the shade number, the darker the lens and the more protection it provides. The shade is 11.
The lower numbers are lighter shades for less intensive welding applications, and higher numbers indicate darker shades for more intense welding processes.
