Hello, I'm Dennis Klingman
We're at the lincoln electric customer training lab
And we're going to go over a topic today that's
fairly current
uh... the topic is helmet adjustment for
people with eye correction lenses
uh... i happen to have bifocals
they're a blended bifocal
uh... this works with regular bifocals but if you have a transition
lens
and have resorted to magnification lenses in your helmet to help you see
what you're doing
instead of using your standard glasses, this is a solution for
not using magnifying glasses in your helmet
and for still being able to see.
And it came about with the advent of our VIKING helmet
headgear uh...
alignment
uh... before this helmet we didn't have this opportunity and uh... the
3350 series of the viking helmets has two things that
allows this to happen
one is that hasn't adjustable headgear the can move forwards and backwards in the helmet.
the other is it has a larger lens
the larger lens allows us to use our bifocals with our head
back and still stay in our lens or come down into the
longer distance part of our lenses which allows us to see at a distance
So I'm going to explain how to set this helmet up properly
first of all
the headgear is adjustable forward and back
uh... for youth, when we got young people using helmets, we put it forward
because it keeps the helmet from being so far out of their face and so much weight out in front of them.
but for bifocals you wanna move the head gear back
So we loosen up the
handle on the side and tighten it down.
we moved it back about a half-inch
which translates to a lot more when it comes to how far it comes down on your face
okay we move the head gear back
you can see that weren't were extended in that slot to the rear position
what this does is
the head gear's on your head, it moves the helmet away from your face
and traditional helmets with a standard headgear
with just one position of center position before you can get the helmet down into
your bifocal range, you'll hit your nose.
but by getting the headgear back and the helmet out
now we can bring our helmet clear down into our bifocal range of our glasses
and with a larger lens
we can not only at look at things up close when we're welding them
if we tilt our head down we can start looking at things further and further and further
to
infinity to the top of your glasses
so the first adjustment is to get the uh... headgear moved back
the second thing is when you put it on
is to make sure it comes down far enough
it actually hits my chest, most helmets won't come clear down and hit your chest unless they got
headgear adjusted right so I'm actually below
my bifocal view is right here, my lens is actually coming below my bifocal view
I can see my bifocal through this lens
and i can
transition up a little bit go in the midrange my glasses see further and when
you're and a booth or helping someone else weld, sometimes you've got to be able to
focus at an arms length or that distance and with cheaters
with a magnification lens, it's hard to focus that far away
but with your glasses
you can tilt your head down and see that distance clear and as you get back
closer and tilt your head back you can see clear
so it actually
doesn't just replace uh... magnification lenses
it actually does a better job than them and we can focus that any distance you
can focus that with your glasses with your helmet on
the helmet's capable of magnification lenses and some people like them
but they come in set
increments, 1.25. 1.50, 2.0
and you go from that
to looking above or below that lens
to nothing
with your glasses, you've got the best capability of all
so thanks for your time
if you have more questions you can go to lincolnelectric.com
lots and lots of good information on that website
