About This

• 1. IMPORTANT FIT NOTICE: Thickness is 5/16 inch, which expands to 3/8 inch when combined with the protective lens(Nonessential), Please verify the compatibility of this 2x4 auto darkening welding lens with your equipment to ensure a proper fit, especially if you are using standard welding lens 2x4.25 or welding lens 2x4 1/4 settings
• 2. NOTICE FOR TIG WELDING: Our autodark welding lens 2x4 is ideal for nearly all cutting and welding applications, excluding oxy-acetylene, laser, and very low-amperage uses. Note: For DC TIG ≥ 60A, this welding lens 2x4 1/4 auto darkening may flash and reduce battery life. We recommend using this lens for DC TIG ≤ 60A to achieve the best results
• 3. AUTO DARKENING WITH ADJUSTABLE SHADE 5-13 LEVEL: The 2x4-1/4 auto darkening welding lens offers a variable shade range from DIN 5-13, ensuring optimal visibility during welding tasks. It remains transparent before and after welding, darkening within 1/25,000 of a second to protect your eyes, and becomes transparent when welding ceases
• 4. HD TRUE COLOR: Experience enhanced accuracy and visibility with HD true color technology. This feature of the auto darkening lens 2x4 minimizes the need to lift the lens between welds, allowing you to quickly identify errors or hazards
• 5. COMPATIBLE DEVICES: Designed to fit standard 2x4.25-inch welding hoods, pancake masks, and some goggles, this automatic welding lens 2x4 may require slight adjustments for thickness compatibility. It’s suitable for SMAW, GMAW, FCAW, and plasma cutting processes
• 6. SOLAR CHARGING: This 2x4 welding lens auto darkening is solar-powered for prolonged use, reducing the need for frequent battery replacements. It features a replaceable CR1025 battery(If the batteries in it are dead，pleasereplace batteries ), providing approximately 800 hours of use per battery pair, enhancing the usability of the welding lenses auto darkening
• 7. TOP-TIER OPTICAL CLARITY AND CERTIFICATION: With an optical clarity rating of 1/1/1/2 and advanced true-color technology, this 2x4 autodark welding lens meets ANSI Z87.1, CSA Z94.3, CE EN175, and EN379 standards. The high performance, clarity, and protection standards ensure that this auto darkening welding lens remains a top choice for professional welders
