• Auto Darkening Lens for Welding: DIN9~13 shade range with UV&IR resistance; automatically increases or lowers the shade of the lens to reduce eye strain when welding.
• Large Viewing Area for Better View: 4.33’’x3.54’’/11cmx9cm large viewing screen gives you excellent clarity and additional peripheral vision when welding.
• Dual Power Sources for Convenient Use: powered by solar power/lithium batteries; you can continue your work using batteries when solar power runs out, and vice versa.
• Adjustable Speed of Shade Switching: a rotating knob is available for you to control the speed of shade switching and the sensitivity of the lens.
• PP Shell with Sponge-Lining Forehead: PP shell protects you from weld slag and arc light; resistant to high temp, fire, and corrosion; lining with a sponge on the forehead for more comfortable wearing.
