Welder Red Seal · Question
While performing a flux-cored arc welding (FCAW) operation on a stainless steel pipe in a workshop, your arc flash personal protective equipment consists of a welding helmet with a shade 11 lens. You notice a persistent bright afterimage in your vision after each arc strike. What action should you take?
A persistent bright afterimage indicates that the welding lens shade is insufficient for the arc intensity, allowing too much harmful light to reach your eyes.

Question: While performing a flux-cored arc welding (FCAW) operation on a stainless steel pipe in a workshop, your arc flash personal protective equipment consists of a welding helmet with a shade 11 lens. You notice a persistent bright afterimage in your vision after each arc strike. What action should you take?
Answer options: ✅ Increase the shade number of your welding helmet lens.
- Adjust the amperage setting on your welding machine.
- Move closer to the workpiece to get a better view.
- Take frequent breaks to rest your eyes.
Correct answer: Increase the shade number of your welding helmet lens.
Explanation: A persistent bright afterimage indicates that the welding lens shade is insufficient for the arc intensity, allowing too much harmful light to reach your eyes. Increasing the shade number will provide better protection. Adjusting amperage, moving closer, or taking breaks do not address the primary issue of inadequate eye protection.
