What shade number corresponds to gas shielded arc welding (nonferrous) electrodes of 1/16, 3/32, 1/8 and 5/32 inch diameter?

• A. 9
• B. 10
• C. 11
• D. 12

Answer: (C)

Shade numbers protect your eyes from the bright arc, and the required shade for gas-shielded arc welding of nonferrous metals increases with electrode diameter. For common small diameters like 1/16, 3/32, 1/8, and 5/32 inch, the standard protection table specifies shade 11. This level balances safety with visibility for these sizes and this process. Lighter shades would not provide enough protection for the brightness of the nonferrous gas-shielded arc, while a heavier shade isn’t necessary for these diameters.
