The primary purpose of a welding helmet is to protect the eyes and face from radiation. In the welding process, intense light is generated, which can cause serious eye damage such as arc eye or flash burn. The helmet shields the welder from harmful ultraviolet (UV) and infrared (IR) radiation produced during welding, preventing both immediate injury and long-term vision problems. Additionally, the helmet protects against sparks, spatter, and heat, ensuring the welder’s safety.

While keeping the welder warm, providing better visibility, and reducing noise exposure are considerations that might enhance the welding experience or comfort, they are not the primary function of a welding helmet. The critical focus is on the safety aspect, which underscores why proper eye and face protection is essential in welding operations.
