What shade number is medium cutting, 1 inch to 6 inches?

• A. 3
• B. 4
• C. 5
• D. 6

Answer: (B)

Shade numbers tell you how dark the protective lens is. The higher the number, the darker the lens and the more protection it provides from bright flames or arcs. For a medium cutting task, like cutting metal with a flame where you’re not dealing with the most intense welding brightness, you want enough protection without making everything look too dark. A shade of 4 hits that balance: it shields your eyes from the flame’s brightness but still lets you see the edge and fit-up clearly. A lighter shade (like 3) might leave you underprotected for cutting brightness, while a darker shade (like 5 or 6) reduces visibility too much and can slow you down or increase errors. So shade 4 is the typical best fit for medium cutting in the 1 inch to 6 inches range.
