Question: During a stick welding operation, the welder experiences flickering vision and eye discomfort shortly after striking the arc, despite wearing their welding helmet. Upon inspection, they notice a small crack on their auto-darkening lens. What is the immediate and most appropriate action?
Answer options:
- Continue welding using a lower amperage setting ✅ Replace the auto-darkening lens immediately
- Switch to plain safety glasses and finish the task quickly
- Adjust the shade setting of the helmet to a darker level
Correct answer: Replace the auto-darkening lens immediately
Explanation: A cracked auto-darkening lens compromises the integrity of the arc flash protection and must be replaced immediately to prevent permanent eye damage from UV and IR radiation. Continuing to weld or switching to non-welding specific eyewear would expose the eyes to harmful radiation. Adjusting the shade will not fix a physical crack in the lens.
