A Quick Start Guide to Auto Darkening Welding Helmets
By Steve Bishop
If you are a welder you are most likely concerned with your safety.
You take precautions by wearing a helmet while welding, but what type
of helmet do you have? The type of helmet you wear can greatly affect
your eye safety. Welders are all too familiar with the possibility of
an arc flash. Exposure to the intense arc flash can cause serious harm
to your eyes including retinal burns. Therefore, it is imperative to
find an auto darkening welding helmet.
What should you look for in an auto darkening welding helmet? First,
verify that the helmet meets the ANSI Z87.1 standard. This standard
guarantees that the helmet will provide the proper protection against
the arc flash. You can choose a lens shade that will suit your comfort
level and needs. Ensure that you wear the helmet properly in the down
position when you weld.

Eliminate irritating shield flipping. Now you can see exactly
where you are at all times and concentrate on the work. A photocell
senses the light from the arc and dims the liquid crystal lens
in a blazingly quick 0.025 milli- seconds. It lightens just as
quickly when you stop. Shade adjusts from #9 to #12 and sensitivity
can be set to suit lighting conditions. This Helmet has a 2.75
clear shade for much easier viewing. Shut off is automatic after
30 minutes at idle. Helmets use two AAA batteries (included) and
feature a low battery warning light |
Welding helmets can change shade by solar powered or battery operated
means. What are the differences between these two methods? Solar powered
shades change when a change in light intensity is detected. They are
designed to automatically darken from the arc. Battery operated shades
must be turned on by the welder to operate like the solar powered shades.
Helmet specifications can be analyzed before making a purchase. You
can research specifications including viewing area, UV/IR protection,
switching speed, power supply, operating temperature, weight, price,
and much more. More detailed information regarding each specification
can be found on many manufacturers' websites.
Find a helmet that feels comfortable atop your head for extended periods
of time. You might want to invest in a helmet that has a sensor bar
if you work in close proximity of other welders. The sensor bar will
help to alleviate any false alarm darkening of your helmet due to neighboring
welders.
Where can I find an auto darkening welding helmet? Auto darkening welding
helmets are sold through many stores, online retailers, and even on
Internet auction websites such as eBay. Prices can range from under
$100 to over $200. Helmets are produced by different manufacturers and
contain a wide range of features. You can even purchase a helmet called
the Hobart Hood Premium 770262 Auto-Darkening Welding Helmet. It comes
in a Stars & Stripes version. This helmet has the American flag
painted on it.
There are plenty of Internet resources available to search for your
perfect welding helmet. You can find welding helmets that align with
your welding duties. An array of options is at your fingertips.
