What shade number is soldering?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

Shade level is chosen based on how much radiant energy the process emits. Soldering produces a small flame with relatively low UV/IR output compared with arc welding, so a light shade is enough to protect the eyes while keeping enough visibility for precise work. A darker shade would make it harder to see the joint and control the soldering, while too light a shade could expose you to UV radiation during longer sessions. Therefore, the standard choice for soldering is shade 2. If the flame is unusually intense or you’re doing very fine work, some setups might use a slightly darker shade, but shade 2 is the typical recommendation for common soldering tasks.
