Weld safely and understand the risks
Without proper knowledge and safety precautions, welding is both dangerous and unhealthy. Most welding processes involve an electric arc flame, so the risk of facial and flesh burns is very high. Both eyes and skin are exposed to bright light and extreme temperatures. Most skin burns begin similar to sunburn, but can become more severe. Eye burns are much more severe, even in the case of minor damage. In addition, the brightness of the welding area can cause flash burns in which ultraviolet light causes inflammation of the cornea and burns the retina of the eye. Without proper protection, the risk of blindness is always present. Welding caps are durable and reliable, and most of them protect the face by greatly reducing exposure.
Welding caps with auto-darkening lenses are designed for optimal eye protection. Standard welding caps protect the eyes from the ultraviolet light emitted during multiple arc welding sessions; exposure to these emissions can cause inflammation of the cornea, known as arc eye or UV keratitis. These dangerous UV rays can cause the same amount of damage, regardless of whether the source is natural or man-made. Unfortunately, once the damage has been done, the symptoms (tough eyes, eyelid twitching, very watery eyes, aversion to bright light, constricted pupils) are not recognized until several hours after exposure. Damage is cumulative, so longer durations and higher frequencies of exposure will result in more severe injury and damage. In these cases, blindness is most likely to occur. However, lens injuries can be easily and effectively prevented by proper protection of welding caps with auto-darkening lenses.
Without proper shielding, other damage to the eye, such as retinal burns and complete loss of vision, may occur. Welding caps are always essential because damage can occur in a relatively short period of time. Electric arc welding operations are potentially very dangerous. The emission of electromagnetic waves (i.e., ultraviolet radiation) can cause many health hazards. UV light is the most common cause of radiation eye damage. In addition to the risk of UV exposure, the welding process can damage the eyes in other ways if not properly protected. These risks are photochemical and thermal damage to the retina. Photochemical damage is the result of exposure to intense blue light. Thermal damage occurs when exposed to visible light and near-infrared radiation. In all cases, the longer the exposure time, the greater the damage. Therefore, making welding caps a very important safety device.
Newer electronic models of welding caps are similar to older models, but with substantial safety and convenience enhancements. For example, all soldering caps include a window filter called a lens hood. In older models, this window is made of tinted or polarized glass. Due to advances in electronics, more modern models use liquid crystal display (LCD) filters or shutters that can better accommodate bright light. Essentially, the auto-darkening lens allows the welder to continue working with an adequate field of view and normal illumination.
