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.
