It's a question often asked by welders - "what shade should I use for my specific welding method". No longer do welders use passive welding helmets that only offer one shade, they now understand the safety and productivity advantages of using auto-darkening welding lens technology. However, auto-darkening lenses do not automatically adjust to visible light (at least yet) so if your desired amperage varies so should your auto darkening welding lens shade. But how do you know what shade to use and won't it change according to the welding method used - Stick, MIG, TIG, Cutting, etc?
Below you will find a recommended shade selection table that outlines what shade should be used according to your specific welding method by amperage level. Simply find the welding process to the left of the table, then follow along the top of the table until you find the amperage level you plan to weld with, link the two and you will find the right shade for you. The shade above or below that outlined in the table can be used based on personal preferences. Hope it helps!
