This is a professional welding tool that can effectively protect the eyes and prevent welding fumes when welding, but will not block the welding sight.

Features:
Large window, higher definition, faster light change, more sensitive recovery.
Longer designed fumes baffle for more effective dust blocking.
4 sensitized probes, wide sensitization range, more efficient soldering.
2 solar panels, automatic charging when soldering, extending lens life.
With low battery alarm indicator to prevent powerless use, which can effectively protect the eyes.
The safe structure design adopts a world famous style and conforms to the ergonomic principle, has sufficient internal space, which makes it easy to operate and comfortable to wear. The soft helmet shell material is resistant to high and low temperatures, corrosion resistance, flame-retardant and light-proof with high strength. It may comprehensively protect your face, neck, ears and so on.
Fine quality liquid crystal optical coating protects welding operator from harmful rays such as ultraviolets rays and infrared rays, etc (level of protection: 16#).
The original design of automatic transform technology is uesd of controlling circuit, which makes it possible for goggles to be able to react to the arcin1/10000 second and change strong light to dark light. As a result, it can protect our eyes from being injured by sudden arc.
Unique design of anti-interference switch avoids not seeing welding object clearly due to complicated surrounding nearby.
Dark shade DIN5-DIN9/DIN9-DIN13, stepless control, set by hand according to actual situation.
Dark to light: 0.1s-0.8s, stepless control.
Can be used for cutting, grinding protection.

Working principle:
Different with traditional passive shading lens, traditional passive shading lenses are made of various additives and pigment. ADF adopts LCD as lens, using the probe on mirror surface to probe the appearance and disappearance of arc when welding, and using the electricity to drive shading level of the LCD to achieve the goal of protecting us from harmful rays, and it also can absolutely reflect ultraviolet rays and ultrared rays. In addition, hands are thoroughly set free, welding is more accurate. Therefore, efficiency is improved.

Package list:
1 * Helmet
1 * User Manual
