You’ll notice that shades 10-12 have more of a range in terms of amperage. Maybe their eyes can handle that, but we wouldn’t recommend it. You may see a welder running dual shield flux core MIG with a shade 9 lens. It is conservative and based on our personal preferences when it comes to lens shades. We have formulated this chart by combining info from other charts, and also by what we have experienced while welding. Shade 7 < 60 amps Shade 8 60-70 amps Shade 9 70-80 amps Shade 10 80-110 amps Shade 11 110-150 amps Shade 12 150-200 amps Shade 13 200 amps and above (be careful) The info below should give you a better idea of which lens is right for your project.

Lens shades vary and can be used for different amperage applications. This is one of the most essential pieces of equipment that a welder can have.
