A welding helmet is specifically designed to protect a welder's face and neck, particularly the eyes and skin, from the intense light, ultraviolet (UV) radiation, and infrared (IR) radiation emitted during the welding process. The helmet's visor is equipped with a special filter that reduces the harmful brightness of the light created by the welding arc while allowing the welder to see the work area. This protection is crucial because exposure to these factors can lead to serious injuries such as burns and conditions like "welders' flash," a painful irritation of the eyes.

While some other options mention aspects of safety, they do not directly relate to the primary function of a welding helmet. For example, noise and vibration affect a welder's surroundings but are not addressed by a welding helmet. Similarly, while the helmet does offer some degree of protection against heat and physical impacts, its primary role is focused on protecting the eyes and skin from the harmful effects of the welding arc. Lastly, though fumes and dust particles can be a hazard in a welding environment, they are typically mitigated through other safety equipment like respirators, rather than the helmet itself.
