Auto darkening welding helmets
Auto darkening welding helmets offer an intuitive protection to modern
welders. These helmets automatically darken when a welder strikes the
arc. They free the hands that in the past had to lift and lower the
faceplate, or remove the helmet altogether to see. Many injuries have
been eliminated by auto darkening helmets because they cover a
welder’s eyes at all times without risking exposure to irritating
fumes and flying debris. By instantly responding to light, these
helmets auto darken when the welder strikes the arc and clear up after
the welder shuts off the arc.
Auto darkening welding helmets prove especially useful to welders
working indoors under poor light conditions. Traditional welding
helmets can literally blind a welder if he has to suddenly cease
welding and kill the arc, leaving himself in total darkness and subject
to fall and/or injury. Because of this, many construction companies now
require all of their welders to use auto darkening welding helmets so
they can see to walk the buildings they are working in. Auto-darkening
helmets also help farmers working outside because they react to
sunlight much like the light an arc. In future years, it is very likely
all welding helmets will be auto darkening not only because they are
more convenient than standard helmets, but also because their
ever-increasing precision allows for customized-eye
protectionâ€"something Federal authorities and Insurance agencies may
soon require.
There are two types of auto darkening helmets that welders use. One is
battery-powered; the other is solar powered. Solar power is more
convenient and efficient when working outside, but work deep inside of
large structures, or even underground, will require battery-powered
helmets. Both employ sensors to “know†when the light brightens,
and when it is time to adjust the special glass in the face shield to
block just the right amount of light. From time to time a welder calls
in with the question, “Won’t the arc from my fellow welder trigger
the auto darkening glass?†The answer could be yes or no, depending
on the model in question. Basic models will grow darker with any
exposure to arc light, regardless of the source. Deluxe auto darkening
helmets have a sensor built into their design that “understandsâ€
the difference between the operator’s arc and a coworker’s arc. For
private individuals working by themselves, it makes little difference,
if any, if the helmet has an auto-darkening sensor like this. For a
company, however, it is best to invest in high-end auto darkening
welding helmets to have a sensor for secondary arc light. It simply
makes sense to do so.
