What shade does a welding shield need to be?

A welding shield typically needs to have a shade number between 10 and 14, depending on the type of welding being performed and the intensity of the light emitted. For example, shade 10 is suitable for gas welding, while shades 11 to 14 are often recommended for MIG, TIG, and arc welding. The darker the shade, the more protection it provides against harmful UV and infrared radiation. Always refer to the manufacturer's guidelines for specific recommendations based on your welding process.
