Welding Masks

The purpose of the welding helmet is to protect the welder’s eyes, face, forehead, neck, and ears from the direct rays of the arc and from flying sparks and sputter. Some welding helmets have an optional “flip lid” which permits the dark filter plate over the opening in the shield to be flipped up so the welder can see while the slag is being chipped from the weld. This protects the welder’s face and eyes from flying slag. Welding helmets are provided with filter plate windows. The filter plate should be capable of absorbing infrared rays, ultraviolet rays, and most of the visible rays emanating from the arc. Speedglass Auto-Darkening filter is a LCD electronic shutter that darkens automatically when sensor detect the bright welding arc. Such glas on welding helmet helps to welder to adjust the position of welding helmet manually which not only saves time but also reduces the risk of exposure to the extremely bright and harmful light generated by the welding process. There are welding helmets with respirator protection systems and systems that help to remove toxic fumes. In the United States, the industry standard for welding helmets is ANSI Z87.1+ which specifies performance of a wide variety of eye protection devices. The standard requires that auto-darkening helmets provide full protection against both UV and IR even when they are not in the darkened state. The standard is voluntary, so buyers should confirm that the helmet is ANSI Z87.1 compliant (indicated by appropriate labeling).
