Welding Helmets To Protect Your Eyes

Welding helmets are one of the most popular accessories for someone engaged in welding. Indeed, the popular vision of the welder would not be complete without the helmet. Our national mythology includes  wearing welding helmets and protective face plating. But, what should you know about welding helmets before acquiring and using them? What popular questions should you ask concerning welding helmets?

The first ask to ask is what is the lens shade, and which one should be old for look protection? A popular misconception is that the lens shade number equates to the amount of protection given to the eyes. These people think that the higher the number, the more protection provided. Not so. The number, great have sunglasses, indicates the darkness provided the shade and should be old to take the most comfortable shade. Most welding experts suggest selecting a shade that lets you look the weld puddle most clearly and the one that helps you the most when welding.

The second popular ask is, that self-darkening helmets don't begin to darken until the welding arc is fired, giving a split second without apparent protection. Will this brief period lead to look damage? The answer is that big quality helmets with auto darkening shades provide protection from both ultra violet and infrared radiation, even when the helmet is not yet activated.

The third ask is, which type of helmet is better, battery powered or solar powered? The answer to this, as you might expect, is personal preference. Both type of helmets work fine. Most battery-operated helmets have a feature that saves power by turning off the power after the helmet has been sitting lazy for a while. So, for this reason a welder using a battery-powered helmet should pay attention and make definite that his helmet remains on to avoid arc burn. Also, some take the convenience of solar powered helmets because they are always on.

The fourth popular ask is should a welder decide a fixed shade or a variable shade? The answer is if a welder is always using the same arc welding process and using the same material each time, then a fixed shade if fine. But most welders use several types of materials and their welding duties entail many different welding applications. In this case, a variable shake will adjust for different conditions and be preferable.

Other features that should be sought in a welding helmet are: lightness of weight; a sensor bar that will limit the field of response to avoid having your helmet triggered by the guy next to you; fat adjustability to provide a better fit - especially important for welders who wear glasses; quality and price.

Keep these questions and the corresponding answers in mind when picking out a welding helmet and you'll have a part of equipment that will help you professionally for many years to come. A welding helmet is one of the most important pieces of safety equipment, along with safety glasses and boots.
