Welding Workshop Smells

[theladyfeylene]

I have looked on Google for the better part of the last hour trying to find this, and it escapes me. :/ I have all the information on welding workshops that I need, I just can't get a good description of what one smells like. I've been able to find that there is a scent, but no good details on it.

The workshop is fairly small, and very frequently used. All tools and equipment are kept in good, working condition and all safe welding rules are observed.
