(Summary description)The electric welding mask face shield is a tool to protect the safety of welding workers. The light sensing system on its lens can drive the liquid crystal to change color and shade the light at the moment when the welding arc is detected, which can filter out harmful light well, protect workers' eyes and faces and avoid radiation damage. Let me introduce you the national standard for using electric welding face shield as below: 1. Materials of welding face shield must be made from non-conductive materials. The burning speed in the fire resistance test shall be less than 760mm/min. After soaking the metal parts in 10% salt solution for 15 minutes, taking them out, drying them at room temperature for 24 hours without wiping off the surface liquid, and then washing them with warm water, the observed surface shall have no change. Then the metal parts are qualified. 2. Weight and thickness: The headband face shield shall weigh less than 560g and the hand face shield less than 500g, excluding the weight of welding optical filter and protection glass. 3. The size of welding face shield shall comply with the relevant provisions. 4. The optical performance and strength requirements of the filter and protection glass of welding face shield shall be the same as those of the welding goggles. 5. Structural requirements: the sizes of observation window, optical filter and protection glass shall match each other, and they shall have good fixing parts for them, so as not to leak radiation light from the gap. Rivets and other parts shall be firm, without loosening and falling off. In addition, the metal parts shall not be in contact with the human face. It shall convenient for the front hanging glasses to flip up and down. In short, the design of the welding face shield shall not only be scientific to achieve the protection effect, but also meet the humanized needs of use.
