Question: A welder is setting up for shielded metal arc welding (SMAW) in a shop environment. Which of the following is the minimum recommended shade number for the filter plate in their welding helmet to protect against arc flash?
Answer options: ✅ Shade 10
- Shade 5
- Shade 14
- Shade 8
Correct answer: Shade 10
Explanation: For SMAW applications, a minimum shade 10 filter plate is generally recommended to provide adequate protection against the intense ultraviolet and infrared radiation from the arc. Shades like 5 or 8 are typically too light, while shade 14 might be unnecessarily dark for general SMAW, making it difficult to see the weld pool.
