Ideal for more experienced welders, the HW200 Auto Darkening (ADF) welding helmet incorporates a high-quality filter with a sleek and lightweight helmet shell, and features solar-powered adjustable Shade 9-13 ADF technology for advanced welding applications. The HW200 also features sensitivity and delay adjustments for customizable filter settings. When a welding job requires more than a standard passive filter, ADF helmets provide greater protection, superior comfort and eliminate the need for constant adjustments, allowing for more time spent welding.
