Economical Auto Darkening Welding Helmet, Shade 4 9 to 13, Head Mounted Protective Welding Mask

Technology & Construction Integrates auto-darkening technology with a liquid crystal filter that adjusts shade between 4 (light) and 9-13 (dark). The helmet features cotton lining and sweat-resistant sheepskin for comfort, along with a rack-type headframe for easy adjustment.

The auto-darkening filter transitions rapidly (≤0.00004s) between light and dark states, providing clear pre-welding visibility and instant protection during welding. The adjustable shade range (4/9-13) and comfortable lining make it suitable for various welding techniques and extended use. Protective Capabilities Shields against intense welding light, UV, IR rays, heat, and flying sparks. The auto-darkening feature ensures eyes are protected instantly when welding starts, reducing the risk of eye injuries.
