What shade number is associated with 5/16, 3/8 inch diameter electrodes?

• A. 12
• B. 13
• C. 14
• D. 15

Answer: (C)

In welding, the shade of your protective filter is chosen to match how bright the arc will be. The arc gets brighter as electrode diameter increases, so larger electrodes require a darker shade to block the intense light and radiation. For electrodes that are 5/16 inch and 3/8 inch in diameter, the standard guidance is to use a darker shade, typically shade 14. This level of filtration helps protect the eyes from the strong ultraviolet, visible, and infrared radiation produced by those larger electrodes. Lighter shades would not provide enough protection at the currents used with those sizes, while the darker shade aligns with common safety charts and procedures.
