ultraviolet light
An electric welding arc produces ultraviolet light and the UV light will damage the retina. With a good welding helmet, your eyes will be protected, but you must have the proper shade (somewhere between 9 and 14 depending on your amperage) and if using an auto-darkening helmet, it must switch on quickly.

Emissions from welding can be heat, light, sparks, slag, and smoke. Each one can be hazardous. Work clothes, leather gloves, and boots can help protect you from heat, light, sparks, and slag. A welding helmet with the correct shade lens will protect your face and eyes from heat, light, sparks and some of the smoke. A means to remove the smoke is very important. Inhaling it can cause long term lung problems. The light can be especially dangerous to your eyes and anyone that is exposed to it. It can blind you.
a good welding helmet must be tolerable to very high temperatures. It should be large enough to protect your face and neck. It should be light in weight. It should have a comfortable headband.
because when you strike an arc underwater, the light attracts sharks, and then they eat you.
A simplified explanation is that the antenna does for radio waves what a lens does for light because of physics.
The welding lens filters out much of the ultra violet light produced by welding.
A welding mask is used to protect the face and head from sparks, flying metals and heat. It protects the eyes from dangerous ultraviolet light and infrared light. Without the mask, the cornea of the eye can be severely damaged.
During the light dependent reaction, it produced Oxygen and Hydrogen..hope that can help...:D

No that is not true. Only energy of light is used

Chemical energy is produced. Light energy is used

The light given off by high voltage arc welding is most harmful but over time, prolonged exposure to the light from shield-gas, oxyacetylene plasma cutting, and torch cutting can cause bleeding behind the macula.
