Automatic dimming welding glasses

Normally we see welders wearing goggles when doing welding. We know that the brightness of electric welding is very high. If we do not take good labor protection measures, it is easy to hit the eyes, causing symptoms such as redness, swelling, ulceration, and long-term tears. In recent years, welding glasses and automatic dimming glasses have appeared. They can automatically adjust the field of vision according to the brightness of the outside world. Let's take a look at this aspect.

Automatic dimming welding glasses

Automatic darkening welding helmet, senses the welding arc through electronic contact sensor. An advanced welding protective mask with automatically changing lens color. Can reduce the visual fatigue of welders.

Before welding, the light green color is observed through the auto-darkening welding helmet lens, which is convenient for accurate arc initiation and welding.

The moment the welding arc is ignited, the lens automatically changes to a dark color (adjust the number on the welding helmet lens according to the actual welding current. The larger the number, the darker the color).

When welding is completed, the lens automatically returns to light green. It is convenient to strike arc welding again.

Ordinary traditional masks have the following defects:

Disadvantage 1: Using ordinary black glass lenses, especially blind welding and bare welding are inevitable during the arc starting process. Long-term welding will accelerate the fatigue and injury of welders and affect the efficiency and quality of welding operations. It will also inevitably cause waste of welding materials and a high rate of rework.

Disadvantage 2: The black glass lenses used in ordinary traditional masks can only absorb the strong light generated by welding, but cannot filter the infrared and ultraviolet rays generated in large quantities during welding, forming secondary radiation. Infrared radiation can cause cataracts; ultraviolet rays can cause damage to the cornea and lens of the eyes, leading to blindness and cataracts, and may also cause dermatitis and skin cancer;

Disadvantage 3: Ordinary traditional masks cannot provide operators with the best observation darkness due to the use of single-color numbers, which greatly affects the observation and control of the welding molten pool and the formation of good welds, and causes slag inclusions, undercuts, pores, incomplete penetration and welding cracks, destroys the flatness and roughness of non-welding surfaces and other defects, affecting the overall welding yield.

Performance advantages of Weihe automatic darkening welding helmet

Weihe automatic light-changing welding helmet adopts LCD photoelectric control technology to realize automatic conversion of light and dark states of 0.5MS (), 0.1MS (basic), and 0.04MS (professional). The darkness can be freely adjusted according to the welding method, arc strength and personal operating habits, ensuring that the welding part can be clearly observed during welding preparation and welding. While creating a safe and comfortable welding working condition, it greatly improves the work efficiency and quality of welders.
