• Large Viewing Area for a Clear, Wide Field of Vision|： This auto-darkening welding filter features a generous viewing area of approximately 100x67mm, offering a broader and clearer sight picture of your weld zone. The expanded view can help reduce eye strain during prolonged work, making it easier to track the arc and weld puddle—ideal for detailed work or applications where better peripheral vision is beneficial.
• Auto-Darkening Response for Instant Eye Protection： Equipped with four high-sensitivity sensors that trigger darkening instantly upon arc detection (with adjustable response time). The shade level is continuously adjustable from DIN5 to DIN13 to match different welding processes and amperages. This design aims to effectively filter intense light and harmful U V radiation (U VB protection up to DIN16), helping to minimize eye strain and potential damage.
• Solar & Lithium Battery Dual Power for Extended Runtime： The lens is powered by a combination of a solar panel and two built-in CR 2450 lithium batteries. The solar panel assists in charging during use, helping to extend battery life. A low-voltage alarm alerts you when batteries need replacement, aiming to reduce the risk of protection failure due to power loss and supporting consistent operation over long sessions.
• Built-in Grind Mode & Delay Adjustment for Versatility： In addition to welding modes, it includes a dedicated grind mode (fixed at DIN4), allowing you to switch tasks without removing your helmet. The shutdown delay is adjustable from 0.1 to 1.0 seconds to suit different welding rhythms, intended to improve workflow continuity and efficiency.
• Durable PA/PP Housing, Lightweight & Impact-Resis tant： The housing is constructed from PA and PP engineering plastics, offering good toughness, corr osion resistance, and scratch resistance. The lightweight design aims to reduce wearer fatigue, while the robust structure helps protect the internal optical components, making it suitable for workshop environments and promoting long-term reliability.
