Why should helmet shade and PPE selection follow the welding process and current?

• A. Because different welding processes and currents produce different arc radiation and heat, PPE selection follows the process and current.
• B. Because PPE is optional.
• C. Because PPE color matches the helmet.
• D. Because PPE never changes.

Answer: (A)

Arcing radiation and heat aren’t the same for every welding job; the amount of UV/visible/IR radiation and the heat you feel depends on the welding process and the current. Because of that, the helmet shade needs to be chosen to block enough of that radiation so your eyes are protected while you can still see clearly, and the rest of your PPE should be matched to the level of heat, spatter, and fumes the process and current produce. Higher-energy arcs from some processes or higher currents demand a darker shade and more protective gear, while lower-energy setups don’t require as much. PPE color doesn’t affect protection, and PPE isn’t optional—each welding situation calls for appropriate protection that matches the process and current to keep you safe.
