一种新型的电焊护目镜

A NEW TYPE OF WELDING GOGGLES

提出了一种新型的电焊护目镜,它是由光电控制电路、变色镜片、双防(防红外、紫外)透明玻璃镜片构成。其特点是护目镜随弧光的开启自动变暗,而随弧光的停止又自动变亮;在弧焊作业过程中,操作者不需移动护目镜;抗各种背景光干扰,该护目镜已通过省科委组织的鉴定。

A new type of welding goggles is mentioned. It is formed of optoelectronic-controled circuit and change-colour lens. Double-protect (both protecting Imfra-red and Ultra Violet) transparent glass lens. Its characteristic is that the goggles immediately turn dark from light state after arc-starting- When arclight disappears the goggles will turn to be light automatically. In the course of welding the welder need not move the goggles. Resisting the interfere of various setting lights. The goggles have passed the appraisal made by He nan Province Science and Technology Committee.
