High Quality Auto darkening Welding Helmets/Mask   Characteristic:  1.Reliable change in light with 1/25000s 2.Advanced filtering technique, well-proportioned transmission of light, clear image formation 3.Shading number is 3 before feeling light, provide ample light for preparation and exact polishing   Why to use auto darkening welding mask? Eye protection: Hand shield: cover your eyes before arcing, or the harmful light will cause damage to your eyes Fillet welding mask: When welding by hands, we should use neck strength to shake off the weld cap at the moment of the welding. Or it will cause damage to the eyes. Working for a long time will cause disease of the neck. Auto darkening welding mask: Probe senses the arc automatically, and LCD screen turns black quickly. It is safe, reliable, and won’t damage your eyes Working efficiency: need mechanical movement to cover the eyes and remove goggles to check the accomplishment Every time you finish welding, you should lift the mask to check the accomplishmen There is no need to repeat covering your eyes before arcing. Therefore efficiency is improved. Welding quality in order to protect the eyes, welding quality is influenced In order to protect the eyes, welding quality is influenced Hands are thoroughly set free, welding is more exacr The technical parameters                           DSF9040J              DSF9040             DSF9242               DSF9848
