Where can I find the electric arc furnace?

So I was looking though the debug spawning menu and I saw an pseudo item for an electric arc furnace which then led me to looking up the actual furniture as well as realizing that all the furniture power tools are useable. I can find all of the furniture tools except for the electric arc furnace. So where does that particular furniture spawn?

I think I saw one in my Lab Start, in the new four-story lab building in the “maintenance room” section of the ground floor. Unfortunately some mi-go got in early on, and I don’t have a save from before they smashed everything.
