Tecmen Adf815s Welding Helmet.

The Tecmen ADF815S is a high-performance, industrial-grade auto-darkening filter (ADF) often paired with the TM15 or TM24 helmet shells. Known for its "True Color" technology and elite optical rating, it is a favorite for professional welders who need precision in complex environments

Technical PerformanceOptical Class: 1/1/1/1 – This is the highest possible rating for optical clarity, light diffusion, homogeneity, and angle dependence, providing a distortion-free view.3Shade Range:Light State: DIN 3.5 (provides a very clear view of the workpiece when not welding).4Dark State: Variable DIN 5–8 / 9–13 (suitable for TIG, MIG, Stick, and Plasma).5Sensors: 4 Independent Arc Sensors ensure the lens darkens even if one or two sensors are obstructed during out-of-position welding.6Switching Speed: 7$1/25,000 text{ sec}$ from light to dark, providing near-instant eye protection.8Power Supply: Solar cells with 2x replaceable CR2450 lithium batteries, significantly extending the life of the unit.9Key Features for ProfessionalsExternal Grinding Mode: Includes an external button or dial that allows you to lock the lens in "Light State" for grinding without removing your gloves or the helmet.10ReaLens™ Technology: Tecmen’s proprietary technology that improves color perception, allowing you to see the weld puddle and heat zone in true color rather than the traditional lime-green tint.Infinitely Adjustable: Dial knobs for sensitivity and delay (time from dark back to light) allow for "surgical" precision depending on the ambient light of your shop.11Pivot Headgear: Designed with a balanced center of gravity to reduce neck strain during long shifts.12
