I didn't watch the video, but the result would be a "Soldering Copper", not a soldering iron...

They are always of copper, iron wouldn’t work, and in the UK at least, they have always been termed “irons”. I thought that the video was instructive, although I am surprised anybody has a need for them.

There are times when you need to supply a fair amount of heat but can not use an open flame. The thermal capacity of copper is ideal for traditional tin/led or silver solder.
I wonder where to get large chunks of copper like that? I have seen some pretty big pieces of copper bar grounding plates in data centers. Big $$$ though.

Any one know about this?
