GTAW exposure is associated with what eye/skin hazard?

Explanation:
Ultraviolet radiation from the welding arc is the eye and skin hazard in GTAW. The arc emits strong UV light that can damage the cornea and skin in a very short time, leading to conditions like arc eye (photokeratitis) and sunburn-like skin burns. That’s why shielding is essential: a welding helmet with an appropriate UV-filtering shade and protective clothing to block UV exposure. Infrared and visible light are also produced, but UV is the primary concern for eye and skin hazards in this context, and there is indeed UV exposure rather than none. X-rays are not the typical hazard associated with GTAW.
