Lechnical Auto Darkening Welding Goggles for TIG MIG MMA Professional Weld Glasses Goggles Multifunction Utility Tool(Random color, purple or green)

• 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 housing material is resistant to high and low temperatures, corrosion resistance, flame-retardant and light-proof with high strength.
• This product can 360-degree comprehensive deodorization and sterilization, safe, and also efficient, which can give you a better using experience.
• Fine quality liquid crystal optical coating protects welding operator from harmful rays such as ultraviolets rays and infrared rays, etc (level of conservation: 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 arcin 3/10000 second and change strong light to dark light. As a result, it can protects our eyes from being injured by sudden arc.
• Special design of anti-interference switch avoids not seeing welding object clearly due to complicated surrounding nearby.

Description This is a professional welding tool that can effectively protects the eyes and refrain welding fumes when welding, but will not block the welding sight. Specifications: Main material: Plastics Color: black Active viewing area: 122.5 * 35mm / 4.8 * 1.4in Light shade: DIN3.5 Dark shade: DIN5~DIN9 / DIN9~DIN13 Way to shift dark state: outer, stepless shift Switching time: ≤3/10000s Sensitivity adjustment: stepless control Delay time: 0.1s~1.0s Power supply: 1 * CR2450 button battery, 3V, 550mAh (included) Operating temperature: -5℃~+55℃ Sensors to weld arc: 2 Protects grade against UVB: DIN16 Grind: YES Cut: YES Low battery: YES Test: no Goggles weight: 195g / 6.9ounce Package size: 210 * 100 * 90mm / 8.3 * 3.9 * 3.5in Package weight: 230g / 8.1ounce 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 you 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 * Goggles 1 * User Manual
