Re: [Shop-talk] Welding auto-darkening helmet

Typically these shields default to dark if there's no power, though I don't
know about the Hazard Fraught models.

One other consideration is that even though they may not darken for some
reason, there's supposed to be adequate UV protection even in the "light"
condition.  It may not be comfortable to view welding through a light lens,
but it's not supposed to be harmful, so testing shouldn't be particularly
hazardous.

And, like Jeff, mine (an old Sellstrom that uses AAA battteries) darkens in
sunlight when it's on and has good batteries.

My Harbor Freight MIG welder and welding helmet have been on the shelf for a
few years gathering dust.  I might have an excuse to use both of them soon.
I took a peak at the helmet thinking maybe the batteries might need
replacing, but it doesn't appear to use any.. So it looks like it uses a
panel of some kind to detect the light from the arc and flips on and darkens
the shield.  I took a look at it and all seems to be in order.  I remember
using it with good success before.

So I just want to be safe here, is there anything I can/should do to test
this out so I know it will work when I spark up the welder?  It didn't seem
to respond much to normal flashlight light...  My retinas thank you. -PJ
