Is Auto-dimming Welding Mask A Good Way To Improve Welding Efficiency？

Welding Mask as the most commonly used protective equipment for welders has gone through the history of more than 100 years. The traditional welding mask uses colored glass as a welding filter mounted on the hand-held mask, which is lifted to see the welding site each time the arc is started, and the mask is quickly moved to the face after the arc is started. The such operation often leads to short exposure to arc radiation. In the long run, the arc light damage to the eyes and face will bring welder photophobia, irreversible loss of vision, and even cataract and other symptoms.

With liquid crystal applications booming in the 1960s, Swedish scientists invented and patented the world's first automatic variable light filter (ADF) in 1976.

In the decades since the first mask equipped with Speedglas™ welding filters was released in 1981, 3M™Speedglas™ Auto-Dimming welding masks have evolved over time.

Compared with the traditional black glass welding filter hand-held mask, the automatic dimming welding mask has many advantages.

From a welding operation perspective, the auto-dimming welding mask gives the welder a clear view of the field before welding, accurately locating the solder joints, and avoiding blind and bare welding. In operation at room temperature 0.1-millisecond variable speed, the convenient welder control weld formation, and improve welding quality and production efficiency. And the filter automatically brightens after welding, so that the welder can easily observe the solder spot situation, but also a grinding operation, no need to lift the screen down, simplify the working procedure, and improve the efficiency.

From the perspective of safety and health, the automatic variable light performance provides reliable eye and face protection, it avoids the occurrence of injuries such as thermal cracking of black glass, harmful light radiation exposure, and other accidents, but also alleviates the eye fatigue of welders and the fatigue caused by frequent lifting and lowering of the welding cap.

An automatic dimming welding mask is not only a piece of protective equipment but also an indispensable "weapon" in welding operations, to help greatly improve the quality and efficiency of welding, in today's development of science and technology to provide more powerful safety protection for welders.

So how to choose a good welding mask? What are the factors to consider?

1. Selection of shading number of welding filter

ADF (automatic variable light filter) is the core component of the welding mask. The automatic dimming welding mask sensor automatically senses arc light, liquid crystal dimming screen quickly black, safe, and reliable, before the arc can clearly see the welding parts, automatic dimming at the moment of arc. In the welding preparation is the bright state, easy to observe by the welder; It can be converted to a dark state within 0.1ms after arcing, without manual replacement of lenses with different shading sizes, so as to greatly improve the welding efficiency. At the same time, the ADF usually has multiple shading numbers for selection to adapt to different welding operations, bright state to ensure a clear field of vision, dark state welding, more clear weld pool. The selection of ADF shading number is related to many factors such as welding method and technology. It is recommended to choose an automatic dimming welding mask with a large shading number to meet various welding methods. At the same time, some welding masks with stepless adjustment functions can ensure adjustment to any value in a continuous range to solve the problem of individual differences. 

2. Selection of mask structure form

According to the structure form, welding protective masks can be divided into handheld and headwear. The biggest feature of the handheld welder mask is that it is cheap, but the disadvantage is also very obvious, that is, it cannot be used for accurate welding operations with both hands and is not suitable for welding operations in tight Spaces. For welding operations with high welding quality or special stations, a head-mounted welder protective mask has obvious advantages, which can free hands and ensure efficient welding work.
