AWTOOLS AW Welding Helmet Auto LYG-4S Auto-Darkening Welding Mask with Grind Mode, DIN 9-13, Large Viewing Area

Professional auto-darkening welding helmet engineered for precision and safety in MIG, TIG, MMA, and plasma cutting applications. The AWTOOLS LYG-4S delivers exceptional optical clarity with a 1/1/1/2 optical class and a wide 92 x 42 mm viewing area, ensuring a clear view of the weld pool and surrounding workpiece. Its advanced auto-darkening filter transitions from light state DIN 4 to dark state DIN 9-13 in just 1/25,000 second, protecting your eyes from harmful radiation while maintaining full visibility. The helmet features permanent DIN 16 UV/IR protection, even in light state, and an external grind mode switch for versatility between welding and grinding tasks without removing the helmet.

Advantages

Dual arc sensors with adjustable sensitivity ensure reliable arc detection from any angle, while the adjustable delay time (0.1–1.0 s) lets you fine-tune the dark-to-light transition to match your workflow. The solar cell with replaceable CR2032 lithium battery provides long-lasting power, and a low battery indicator alerts you before performance drops. The high-impact polyamide shell offers durability and comfort, with an operating temperature range of -5°C to +55°C for use in diverse environments.
