The choice of welding helmets
Welding helmets are one of the most important items of protection equipment anyone in the business would need; welding exposes the workers to high intensity light, ultraviolets and infrareds that can cause irrecoverable retinal lesions. Welding helmets come in a variety of seizes and forms, but the most important thing is that they be both secure and comfortable. The best tools to use are the lightweight ones since, too heavy a helmet can tire the neck and the back, particularly since welding implies work in very awkward positions. Lightness is not the only feature of this piece of equipment, welding helmets also require durability.
Considered the best welding helmets available, the items with auto-darkening properties change their color within a fraction of a millisecond, as the electric arc is struck. The detection of the flash is so rapid that you don't even notice the moment when the lens has gone dark; furthermore auto-darkening welding helmets offer protection even when the filter is not activated, this prevents the UV and IR from harming your eyes even in the absence of high intensity light. Regular welding helmets are not more expensive than $40, but the more sophisticated the technology, the higher the prices.
What does improper eye protection lead to? First of all we should say that developing certain work-related health affection is not uncommon at all, and it usually happens within years. The sight-hand coordination is not the same and cataract is often the consequence of faulty welding protection equipment. When choosing welding helmets it is important to be aware of the relationship between light intensity and the color shade of the protection item. The filter shade is the one that regulates the amount of light that reaches the eyes: too dark a filter may prevent the welder from getting work details, whereas too light a shade increases the risk of eye damage.
The filters of the welding helmets are numbered to indicate darkness degree; welders can make the right choice with the help of the standard selector charts that allow matching the filter shade with the type of application you need. At work completion, welding helmets must be cleaned of dust and dirt; there are special solutions designed to preserve the coatings intact. Afterwards, the equipment should be deposited in an area that is not exposed to direct sunlight, dust and moisture since such elements may diminish effectiveness.
