Welding Helmets
By Josh Riverside
Welding is a well-established manufacturing process used in innumerous industries. However, there are several potential hazards associated with it. The safety hazards associated with arc welding involve arc radiation, air contamination, electric shock, fire, and explosion of compressed gases. The sparks generated by many welding processes are very hazardous to eyes and face of the operator. Thus, to ensure maximum safety for the welder, a welding helmet is unavoidable.
Helmet is the primary precaution gear for a welding machine operator. A welding helmet is often outfitted with an auto darkening mechanism. Auto darkening is a feature that allows the operator to view and prepare the work piece through a lens that reacts instantly to the arc and darkens to a selected shade level. Some of the designs in this category offer a viewing area that is 30% larger than conventional helmets. These helmets also shield the eyes against harmful UV and infrared rays. Some modern helmets also feature a replaceable battery or a solar assisted lens technology.
The helmets have a comfortable and well-balanced design with an improvised ratchet-style headgear that provides more control and an exclusive comfort cushion to reduce fatigue. In addition, these helmets are four ounces lighter than the conventional ones.
The helmets even feature industry-leading integrated graphics and adjustable controls such as 9-13 shade control, lens sensitivity, and delays. Moreover, the helmets are also outfitted with auto-off circuitry at 15-20 minutes, and a low battery indicator.
Some helmets are exclusively outfitted with a rubber gasket, which provides excellent lens protection and can be changed easily. In addition, most models have an excellent magnifying holding lens system that allows vertical adjustments.
Helmets are certainly very crucial during the process of welding as the process produces a great amount of UV rays and radiation. These equipments not only protect the eyes from the harmful radiation exposure but also act as a shield against flying debris.
