The most common eye injuries from UV/IR radiation are retinal burns and flash burns to the cornea. These high intensity light injuries are preventable when the proper protection is worn and used accordingly. Different applications require different protection, and it is critical to choose the equipment that is most appropriate for your job situation.
Arc-eye occurs when the surface of the eye is exposed to excessive ultraviolet (UV) radiation—usually when an arc is accidentally struck while the welding helmet is in the up position or the eyes are otherwise unprotected. Long-term over-exposure to arc radiation is linked to retinal burns, cataracts and skin cancer.
Foreign body eye injuries occur when material such as dust, grinding swarf or weld spatter gets into the eye. When a particle(s) penetrates the outer layer of the eye and enters the eye it is called a penetrating foreign body. These particles or objects are usually traveling at high speed and are commonly made of metal. A penetrating eye injury can be extremely serious, leading to blindness if not detected and treated promptly.
Put simply, auto-darkening welding filters allow welders to keep their eye and face protection — their welding helmet — in place much more often than passive welding filters. If you can always see, the motivation to constantly lift your helmet is significantly reduced, meaning:
One of the most common eye injuries from UV/IR radiation are retinal burns and flash burns to the cornea. We understand that eye protection is a critical issue for all welders and here are our replies to a few of the most frequent questions we hear about our auto-darkening filters
If profitability is defined in terms of protection, one day is enough. But while “protection” sometimes can be difficult to measure, efficiency and weld quality are much easier to gauge. Studies show that you can increase efficiency substantially when using Speedglas auto-darkening filters. Not only can you work faster when you can always see, but you move more efficiently, placing electrodes more precisely. Most “bad weld starts” can be eliminated. Fewer bad welds mean less grinding and higher overall quality levels.pay off chart.
Productivity gains are, of course, dependent on the application. If you do lots of tack welds, you will have much greater productivity gains than a welder doing long seam welds. With that said, this example uses a conservative 15% gain in productivity. If cost for salary is $20 per hour, the welding helmet will pay for itself in approximately two months. In one year, the productivity gain could be up to $6000 in savings (also known as new profits). Note: Dollar amounts are approximate and may vary).
When it comes to welding equipment and safety products, the cliché – “you get what you pay for” – has never rung more truly. Welding equipment and Personal Protective Equipment (PPE) should always be selected based on the individual’s circumstances, not the price. The optimal choice of welding filter depends, most of all, on type of welding process. But also on personal preferences that incorporate the complete welding helmet system, like size of viewing area, peripherial view, perceived weight and balance, need of additional protection etc.
Before you select a model, ask yourself:
This is a long-term investment: a variable welding filter offers more flexible features for new working conditions. Always contact your Safety Engineer, Safety Officer or other safety experts if there are any doubts regarding appropriate eye protection in your working situation.
