introduction and advantage

Good Material and Durability Features

The welding helmet is constructed using superior materials, ensuring enhanced durability and the ability to withstand tough working conditions, resulting in a longer lifespan. In addition, it complies with all relevant safety standards (ANSI, CE, CSA, AS/NZS), offering welders improved protection.

Highest Optical Class 1/1/1/1, Better using experience

Our auto darkening filters boast an exceptional optical classification of 1/1/1/1, which offers user good advantage of :

Clarity - ensures excellent optical clarity, allowing welders to clearly see the work area and weld puddle. 

Uniformity-provides uniform shading and brightness across the entire viewing area, resulting in consistent visibility during welding operations. 

Deformation-the auto darkening filter minimizes deformation and provides an accurate, realistic view of the welding process. 

Diffusion of light - effectively diffuses light, reduces glare and protects the welder's eyes from harmful radiation. 

More Accurate Shade Control, Better Protection in Welding

Through the utilization of advanced technology, we have developed On-line Automatic Testing, which utilizes our proprietary chip for more accurate shade testing & adjustment to provide more accurate shade control auto darkening filter products, enabling welders to work with precision and confidence and enhances safety by providing the right level of protection against harmful light and radiation.
