I am a electrician and not a dirt doctor.

When something I read flies in the face of what I read previously and know as fact, then I will challenge it.

If you are a dirt doctor, then challenge this wacko and not me.

What I know about the sun came from NOAA. I consider their data to be true.

BTW, I have used plasma cutters, welders and worked for a steel foundry. I know what iron can and can't do.

There is no such thing as iron gas as far as I know. It forms compounds and alloys, or it oxidizes and is destroyed or turns into something else. It cannot exist as a gas.

Just because we don't know things does not make them automatically untrue.

Google will lead you to new knowlege. Iron Gas on Google

As far as you know... Try a Google search for "gaseous iron," then get back to me.

Under your TIG plasma there would be for a short period of time. Then it cools and condenses back onto the cool substrate. Some may escape the inert gas and oxidize almost instantly giving rust gas. There would be a partial pressure of iron just like carbon dioxide, argon, and whatever is in air. That's iron gas, right in your garage or wherever you do steel welding. You probably shouldn't breathe it, and we know you should not breathe zinc. Pure iron gas would need nothing more than temperature, iron boiling point 3000 C--that's gas.

Iron would be a gas in the hot part of a star (it's all gas, really). See Subrahmanyan Chandrasekhar's work. Of course, were there much iron in the Sun in a gaseous state, there should be spectral evidence. Again one is looking at temperatures in the millions of degrees whereas welding and foundry work operate in temperatures of only a few thousand degrees.

But these are low-temperature activities. The Sun is somewhat warmer than most people normally experience.
