technical field

The utility model relates to an electric welding mask, in particular to the structure that the goggles of the electric welding mask have two kinds of transparent lenses with different colors.

Background technique

Electric welding is a mechanical processing method that uses a large amount of current to pass through two poles at a certain distance, that is, the arc phenomenon generated at the end point generates high heat, and makes the metal parts or materials at the hot spot welded to each other. In the construction process of electric welding, strong arc light damage will be produced, and high-temperature hot solder or metal scraps will be splashed. Therefore, if the welder performs the above-mentioned electric welding construction, he must be equipped with a welding mask. The goggles protect the eyes so that the eyes will not be hurt by strong light, and at the same time, the face will not be scalded by spraying solder and metal shavings, so as to maintain the safety of construction.

However, the lenses contained in the visor lens group used by the existing commonly used welding masks are all black lenses, so when welding, the welder must cover his face with the welding mask for welding for a while, and remove the welding mask completely for a while. , check the welding results, and repeat this to complete the welding work. However, such a working method is too inefficient and it is easy to cause fatigue to the welder. Therefore, the industry has developed the prior art disclosed in the Taiwan New Patent No. M338648 "Structure Improvement of Electric Welding Masks", in which the black lenses of the goggles are pivoted and overlapped with the transparent lenses, so that the welders can work in the same way.
