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 ultra violet rays and ultrared rays. In addition, hands are thoroughly set free, welding is more accurate. Therefore, efficiency is improved.
