Description
Welding Face Shield or helmet) is mandatory Personal Protective Equipment that provides essential protection for the eyes, face, and neck from the intense light, heat, sparks radiation generated by arc welding processes. Modern auto-darkening helmets feature a specialized electronic lens that automatically darkens upon sensing the weld arc, ensuring the welder can see clearly before welding and is instantly protected once the arc is struck, significantly improving efficiency and safety.
Features:
- Auto-Darkening Filter: The core component is an electronic lens that utilizes sensors to detect the arc flash and instantaneously switches from a light state (e.g., Shade 3 or 4) to a predetermined dark shade (e.g., Shade 9-13) within milliseconds of a second)
- Protection: Provides constant, permanent protection against harmful Ultraviolet radiation, regardless of whether the is in the light or dark state, preventing “welder’s flash” (arc eye)
- Adjustable: Allows the welder to manually adjust the final dark shade level (typically Shade 9 to 13) to match the intensity of the specific welding process and amperage setting
- Sensitivity: Adjusts how easily the sensors detect the arc, preventing accidental darkening from nearby flashes.
- Delay: Controls how long the lens remains dark after the arc stops, preventing flashes from residual heat or quick arc restarts.
