electric welder's helmet Welding machine
Welding mask refers to a tool that protects the safety of the
operator in welding and cutting operations. It is a high-tech product integrating optics, electronics, human
body science, materials science and other disciplines. The combination of high quality LCD and glass plating is used as
the blackout lens, and the light induction system on the lens can
detect the generation and disappearance of arc light during welding
instantaneously, and quickly drive the liquid crystal to achieve
safe and effective filtering of harmful light, so as to protect the
eyes and face of welders to avoid the damage of arc radiation. The welding mask is composed of an observation window, a light
filter, a protective plate and a mask. There are four types of hand-held face mask, headband face mask,
helmet face mask and helmet front hanging glasses face mask.
1. Eye protection: double filter to avoid harmful ultraviolet and
infrared radiation produced by the arc, as well as damage caused by
welding strong light to the eyes, and prevent the occurrence of
electro-optical ophthalmia. 2. Facial protection: effectively
prevent the damage caused to the face by splashing objects and
harmful bodies in the operation, and reduce the occurrence of skin
burns. 3. Respiratory protection: air flow guidance can effectively
reduce the harmful gases and dust released by welding to the body
and prevent the occurrence of pneumoconiosis occupational diseases.
Polymer material molding, high strength, no light leakage is more
suitable for today's trend, complete varieties can adapt to a
variety of working environment needs. Solar light control welding
mask, before the arc can clearly see the welding parts, arc
automatically dimmed at the moment. The light-controlled welding
mask is a new welding mask which uses light detection technology
and liquid crystal technology. The principle is that the internal
photoelectric sensing circuit detects the light generated during
welding (mainly infrared or ultraviolet), amplifies it, triggers
the control circuit of the liquid crystal, and applies the
corresponding driving signal to the liquid crystal of the mask
(transmitted TN liquid crystal) according to the preset light
transmittance. Liquid crystal acting as light valve will change its
light transmittance. The welding will be filtered out to produce
infrared and ultraviolet radiation harmful to the human eye. At the
same time, the bright light is reduced to a low light that the
human eye can withstand. Compared with the traditional welding
mask, it not only protects the health of the operator, but also can
clearly observe the whole process of welding. It is an ideal
replacement for traditional welding masks.
