I bought it for arc welding

I attached it to a helmet and used it. It was a nice feeling. However, since the number is low, I also used hand-held surfaces at the same time.

I am satisfied with the price.

It is convenient not to have it by hand.

It is useful for semi-automatic temporary attachment. Although it may become troublesome and it may shift to a little book intact as it is, there is no problem even with a semi-automatic spark with light blocking degree # 11. As a trick, keep the lens away from the eyes, rather keep the distance (protective eyewear required!). Then you can take a wide field of view and shorten the movement distance of the shading lens by swinging the neck = you can reduce the swing of the neck. Although it is used in conjunction with a mask (stooping of hat) that stops the hanging of the hat, I can not deny that it is heavy again, and since gaps arise, inevitably the necessary parts (per cheekbones, front of the neck We recommend that you paint sunscreen on). Although it is a very useful tool for temporary attachment, even if sunscreen agents are used together, it is better to use the surface in relation to the spark exposure area for book attachment.
Gas welding, gas fusion interruption, electric arc welding (carbon dioxide gas arc welding)

Degree of sharpness of 8 degrees is practically impractical for electrical welding and gas welding because it is incomplete frequency, so gas welding should be at a sharp intensity of 3 degrees and electric welding should be at a shade intensity of 10 degrees . (Electric welding has a brightness of 11 degrees is too dark.)
It is used in vocational training practice at the Employment and Capacity Development Organization Center such as gas welding, gas fusion cutting and arc welding.

With the work hat, do not you think that if you try to lighten the hat attachment glasses as much as possible so that they can be inserted to the back of the eaves of the hat, will it be stable?
