【0.01 MS AUTO-DARKENING 】At PRERUNER, we prioritize the safety and health of welders. Traditional auto-darkening lenses often have slow response times, risking eye injuries like arc eye. Our upgraded auto darkening welding lenses feature two advanced sensors that darken in 0.01 milliseconds, providing immediate protection and significantly reducing injury risk. We believe that continuous innovation and understanding welder needs are key to supporting them effectively 【NO-COATING DESIGN, RESTORING 7 TRUE WELDING COLORS】​Test data shows traditional welding lenses mainly only transmit yellow and green light. The PRERUNER Core Series HD model, however, uses a no-coating design—this feature breaks color transmission limits, presenting up to 7 true colors in welding scenarios​ In both bright workshops and dim sites, the no-coating design reduces color interference, letting welders clearly see the weld pool and seam. It stays highly clear during arc start/end, helping position welds accurately and adjust operations promptly, ensuring better weld precision and quality for excellent results 【TIG APPLICABILITY INSTRUCTIONS】Many customers ask if this auto-darkening lens works for TIG welding — yes, but clarify usage details to avoid issues. TIG arcs are inherently unstable, and this lens uses a light sensor for auto-darkening; its high sensitivity has limitations: lens flickering may happen if the arc starts unstably, current is outside 70A-150A, or in strong light. For users who mainly do TIG welding, use off-range current, or often face unstable arcs, the upcoming PRO version will add "Passive Constant Dark Mode" (full-time dark state) to fix flickering — you can buy the new version then 【BUILT-IN BATTERY & SOLAR PANEL】The PRERUNER Core Series lens uses an integrated "battery + solar panel" power system for maintenance-free welding: arc trigger activates built-in battery’s instant auto-darkening; solar panel captures arc energy for continuous power during welding. Limitations: non-replaceable battery; solar panel only captures energy (no storage). Long inactivity may drain battery (no low-battery alert). Test darkening with a desk lamp first. For stable high-demand welding, upgrade to "adjustable-shade series with replaceable battery" or enhanced versions—flexible power, better for high-intensity work 【STANDARD COMPATIBILITY】Our auto-darkening welding lens features a standard 2x4.25-inch size, ensuring compatibility with most welding helmets, masks, and select welding goggles. At PRERUNER, we are dedicated to delivering a superior welding experience, providing the perfect balance of optimal visibility and reliable protection for every welder 【CERTIFIED SAFETY & RELIABILITY】​At PRERUNER, your safety is our top priority. Our auto-darkening welding lens is rigorously tested and certified to meet the highest industry standards, including ​ANSI Z87.1 and ​CE EN379. These certifications ensure that our lens provides exceptional protection against harmful UV/IR radiation, impact resistance, and reliable performance in all welding conditions. When you choose PRERUNER, you’re choosing a product backed by trusted certifications, giving you complete peace of mind for every weld.
