This indicates that the lens is not filtering out enough UV-- that can
lead to eye damage.

I bought a $40 model with the intent of trying it out. No adjustments.
I found that the lenz was not quite dark enough for me, I could not make
out details in the puddle. For $2 local welding supply sold me a
'darkening lenz', basicly a pice of colored plastic), 1 level, that I
just inserted into the lenz stack. Much better. They also have
magnifying lenses - bought one but haven't tried it out yet.
Big thing I heard was that if you used an auto dark helmet all day long
that your eyes would itch at the end of the day, so I approached long
duration welding sessions with care. So far no issues at all for a
welding session of 5 hours pretty much continuous.
One caution, if you are working on a hard to get to spot in the cage,
you know - all contorted, reaching through the bars, and peeking through
a hole - when you strike the arc if the cells on the top edge of the
lenz are shadowed from the arc - no auto darkening takes place. It
doesn't usually take me very long to kill the arc in these situations.
I also found the extra darkening lenz helps when I break the arc , the
lenz goes clear, and I am looking at the still incandescent weld puddle.
However, it hinders when looking into dark corners.
Thanks,
Jim.
