For SMAW work, the filter lens shade is the most common.

Explanation:
When choosing a filter lens shade, the goal is to protect eyes from the arc’s bright radiant energy while still allowing you to see the weld clearly. For Shielded Metal Arc Welding (SMAW), the most common setting is a shade that provides strong protection but isn’t so dark that you can’t see the puddle and the filler metal well. Shade around 10 hits that balance for typical SMAW current ranges, making it the standard in many shops. Lighter shades (like 9) can be too dim for arc protection at common SMAW currents, while darker shades (11 or 12) reduce visibility too much for everyday welding tasks, though they might be used for very high current or thick joint situations. So, shade 10 is the go-to for routine SMAW work because it offers adequate protection with good arc visibility.
