I don't think welding light is the same. In the first place the eyes are
only a few inches away, and the use is hours at a time. My eyes are never
closer than a yard from the bulb, and the use is minutes. Secondly, I
suspect the wavelength is different.... tho neither of us, I also suspect,
knows that for sure.

It sounds like we're talking about different NuArcs. I've operated one
for 15 or so years, and never noticed any fumes. Are these fumes odorless?

Mine is the sodium mercury vapor -- and for what it's worth, I'll add that
NuArc assured me the light was absolutely harmless..
