What safety equipment is essential during GTAW?

Welding helmets with suitable filters are essential during Gas Tungsten Arc Welding (GTAW) because they protect the welder’s eyes and face from the intense ultraviolet (UV) and infrared (IR) radiation produced by the arc. The helmet's filter lens is specifically designed to reduce harmful light levels while allowing the welder to see the work area clearly. This is crucial since the brightness of the welding arc can cause severe eye damage, such as arc eye, if proper protection is not used. Moreover, the helmet provides physical protection from sparks, heat, and debris that can result from the welding process.

While other options include protective gear, they are not as directly essential to protecting the eyes and face during GTAW. Ear protection may not be necessary in environments where noise is not a significant concern, and leather boots and knee pads offer protection but do not address the hazards specific to the welding process. Gas masks and respirators are generally used in situations involving harmful fumes or airborne contaminants but are not specifically required for GTAW unless there are additional hazards present.
