Solar Energy Automatic Variable Light Welding Mask TIG Spot Welding Helmet with Adjustable Headband Knob

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

Features:
Double protective lens for more effective eye protection.
Headband adjustment knob on the side of the mask can adjust the headband tightness.
The new material cap is light and resistant to falling, heat-resistant and flame retardant.
The mask is designed according to the human face and can block the welding fumes.
Solar panels are automatically charged during soldering to extend service life.
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 protecting 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 design of automatic transform technology is uesd of controlling circuit, which makes it possible for goggles to be able to react to the arcin3/10000 second and change strong light to dark light. As a result, it can protecting 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, stepless control, set by hand according to actual situation.
Dark to light: 0.1s-0.8s, stepless control.

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.
