What shade number is gas welding (medium) 1/8 inch to 1/2 inch?

• A. 4
• B. 5
• C. 6
• D. 7

Answer: (B)

Gas welding uses a bright flame, but not as intense as an electric arc, so the protective filter you need is lighter than for arc welding. For a medium-range weld in the 1/8 inch to 1/2 inch size, the standard shade is 5. This shade provides enough protection from the flame’s brightness while still letting you clearly see the weld pool and edges. Using a lighter shade would offer less protection, while a darker shade would make it harder to see what you’re doing.
