What is the primary purpose of a welding helmet?

The primary purpose of a welding helmet is to protect the welder’s face and eyes from various hazards encountered during the welding process. This includes shielding against harmful ultraviolet (UV) and infrared (IR) radiation produced by the welding arc, which can cause serious eye damage, such as burns to the cornea. Additionally, the helmet is designed to protect against flying sparks, molten metal, and other debris that could injure the welder's face. Proper protection is crucial in maintaining safety and preventing both immediate injuries and long-term health issues related to exposure to harmful elements while welding.

While keeping the welder cool, enhancing visibility, and speeding up the welding process are important considerations in the welding environment, they do not encompass the primary function of the helmet. The helmet's primary role remains focused on safeguarding the welder from injury.
