What equipment is most essential for protecting the welder's eyes during TIG welding?

• A. Full-face respirator
• B. Welding helmet
• C. Monocular safety goggles
• D. Contact lenses

Answer: (B)

Eye protection during TIG welding relies on a welding helmet because it provides a shaded barrier that protects the eyes and face from the intense arc light, ultraviolet and infrared radiation, and heat. The helmet’s lens is rated to filter harmful radiation, reducing glare and preventing retinal damage while allowing clear visibility of the weld. It also shield you from flying debris and spatter that can reach the eyes. Other devices don’t offer the same combination of shielding and shading: a full-face respirator protects lungs but not the eye-brightness or arc radiation; monocular safety goggles cover only one eye and don’t provide complete eye protection or proper shade; and contact lenses offer no protection against radiation, heat, or debris and can complicate safety in welding. So the helmet is the essential tool for safeguarding the welder’s eyes.
