New to this NG. I recently purchased a Lincoln Weld Pak 100 and had a
question on auto-darken helmets.
I purchased an $85 helmet from Harbor Freight that has a reaction time of
The link even shows the time a .0001 seconds, but he box has one less
I passed up the the ones that advertised 1/25000th of a second.
But if my math is correct that is .00004 seconds?!? Or does the manufacturer
really mean .025 seconds. As in, 25 thousandths of a second.
The real question is how much reaction time would be needed to protect my
already old eyes and my teenaged sons, for safetys sake.
If it meets the ANSI standard which IIRC is Z87.1, it should protect against
IR and UV at the equivalent of a #14 welding filter even when it's not dark
so it shouldn't do any damage but you may get "dazzled" and sees spots if it
doesn't darken quickly enough.
That particular helmet isn't the "preferred" one around here. In fact it
looks like the same one that Homier sells on their site and at their
truckload tool sales for $29.99.
I personally have this one:
I've been using it (as a hobbiest) for about 1 1/2 years without any
complaints or problems. Others here recommend this one and I'd buy it over
the one I have if I ever need a new one:
In fact, both of those are currently on sale for $50 as well as a couple of
others that look similar to the 91212 but with flames, etc. so you might
want to take yours back and exchange it. Print out the Web sale pages
before you go to the store. The store in my area has always been willing to
honor Web prices even if their computer doesn't show it on sale.
For just a little more than you paid for the one you bought you could buy
two of these so you and your son can both see what's going on at the same
"I'm not grown up enough to be so old!"
Greetings and Salutations....
Well, I have had one of these HF helmets for some time now,
and, I have to say that I really am happy with it. I think mine
is one of the slower ones...however, I don't think I have been
flashed more than once or twice, and, in those cases, it was because
I was welding in an awkward position and apparently had blocked
They appear to do a very good job of knocking back the UV and
IR (which is the important part). I have not had any problems with
"sandy eyes" or any other signs of excess UV exposure with the
About the only complaint I have about it is that the
ratchets in it are pretty light-weight, so, it will tend to loosen
up as I move around. But then...it is NOT a $200+ Jackson
Ted, and all else who've replied...
Thanks for the insight and wisdom everyone brings to this group. I as a
tinkerer, hobbyist, home repair type of a guy will browse this NG often and
absorb a little more knowledge each time.
Another Ted here. I just tried the camera flash test with my latest
helmet, and I did see the flash, but it was much attenuated from looking
at the camera with no helmet on.
From this I would assume that the flash takes longer to happen than the
response time of the auto-darkening. Playing with the sensitivity
control confirmed that.
OK, OK! Ya caught me. I confess to trying the camera flash trick too. I also
saw the flash, or at least part of it. The faceplate did darken and then
lighten up after the flash was over.
Then I put a mirror inside the helmet and then took a picture. The picture
showed the faceplate darkened, no reflection of the flash came from the
mirror inside the helmet back to the camera. From this and from using the
helmet, I know the auto-darkening is fast, fast, fast. When welding I just
see a little flash before it turns dark. Never enough to get spot before my
eyes. Another thing it lightens up fast too.

Very clever test. This will hereafter be referred to as the "Diamond Jim
Test," and should be referenced every time someone questions whether they
can suffer eye damage due to delays in the autodarkening function.
