NEW GENERATION SCREEN - Upgrade to the new generation screen with a 3.64" x 1.67" view. It features advanced 1/1/1/1 optical clarity lenses and true color technology for a clearer, more realistic view, enhancing efficiency and accuracy (Cheater Lens / Magnifying Lens Compatible Design). FASTER AUTO DARKENING - Upgrade to high-end auto-darkening lenses with two new generation arc sensors, switching from light to dark in just 1/25000 seconds. Brightness and sensitivity are easily adjustable for various environments, making them ideal for TIG/MIG/ARC welding and grinding. Dark state levels: 4/9-13. LONGER USAGE TIME - The welding mask screen is equipped with a solar panel at the front and a CR2450 lithium battery at the back, providing power with a minimum current of ≥5 amps, resulting in longer working hours and greater durability. GREEN MATERIAL - Made from eco-friendly PP materials. Tests show an operating temperature range of -5°C to 55°C, a storage temperature range of -20°C to 70°C, a tensile strength of up to 120 MPa, and a flexural modulus of up to 4000 MPa, ensuring enhanced flexibility for welding helmets. BEST EYE PROTECTION - This welding hood features a 12-in-1 smart filter, with automatic DIN 16 ultraviolet/infrared protection, effectively filtering harmful light to protect the eyes and adapt to various environments. EASIER ADJUSTMENT - The welder helmet features a newly upgraded knob section, allowing for easy adjustment even while wearing gloves. The interior of the helmet has been rearranged for a better fit to the human head, ensuring comfort even during extended wear.
