Weld safely and Know the risks
With out proper knowledge and safety precautions welding can be both dangerous and unhealthy. Most welding processes involve an arc flame, so the risk of facial and flesh burns is very high. Both the eyes and skin can be affected by the bright light and extreme temperature. Most skin burns begin similar to a sunburn, but can get much more serious. Eye burns are much more serious even in the slighter cases of damage. Additionally, the brightness of the weld area can cause flash burns in which ultraviolet light causes inflammation of the cornea and can burn the retinas of the eyes. The risk of blindness is always there if not properly protected. Welding helmets are durable and dependable, the bulk of them protects the face by drastically reducing the amount of exposure.
Welding helmets with an auto darkening lens are specifically designed for optimal protection of the eyes. Standard
chinese butt welding machine manufacturers helmets protect the eyes from ultraviolet emissions released during multiple arc welding processes; exposure to these emissions result in inflammation of the cornea and is known as arc eye or ultraviolet keratitis. These dangerous ultraviolet rays can cause the same amount of damage regardless of the source be it natural or artificial. Unfortunately, the symptoms (gritty painful eyes, eyelid twitchy, very watery eyes, aversion of bright light, pupil constriction) are not recognized until hours after exposure once the damage is already done. Damage is cumulative, so the longer duration and higher frequencies of exposure will result in more serious injuries and damage. In these cases blindness is most likely to occur. However, with the proper protection of a welding helmet with an auto darkening lens injuries are easily and effectively prevented.
