我厂研制成功的JZM-4型弧焊自动调光护目镜,是由电磁接收器、电子线路部件、液品光阀片、电池盒及防红外线片等组成。采用全封闭形塑料外壳结构。其工作原理主要是利用电子线路来控制液晶片的透光率,使护目镜片变暗或变亮,从而起到保护焊工眼睛的作用。它克服了传统电焊面罩上的护目镜透光率不变的缺点,具有良好的防紫、红外线的功能。该弧焊自动调光护目镜适用于各种弧焊方法,并具有使用方便、安全可
Our factory successfully developed JZM-4 arc welding automatic dimming goggles, is composed of electromagnetic receiver, electronic circuit components, light valve tablets, battery boxes and anti-infrared film. The use of fully enclosed plastic shell structure. Its working principle is mainly the use of electronic circuits to control the transmittance of the liquid crystal, so that goggles darken or brighten, which play a role in protecting welders eyes. It overcomes the shortcomings of traditional goggles on the same transmittance of the goggles, has a good anti-purple, infrared function. The arc welding automatic dimming goggles for a variety of arc welding methods, and has easy to use, safe
