i can't tell by looking at the beam.
how do you find out such a thing? we need some sort of spectrometer since
it's bright enough to be detected through almost any filter.

i was planning to just make an opaque, hinged

when the robot is doing something dirty like that. It will help with
ventilation too, which is a bigger problem than arc flash with the plasma
cutter.
but a plasma cutter is such an awesome tool, i think it's totally worth the
annoyance of having to make it safe for puny humans.

Cool! Do you have a model number on there somewhere?
I assume this will be an IR laser if it's a diode array. So if we get a
safety curtain, we'll need one that can block both UV from the plasma
cutter, and IR from the laser. Ditto for safety goggles. I assume that's
feasible, although likely a little harder than protecting against just
one
of those.
