075-190-501 (7/0) 4 ELECTRIC SOLDERING COPPERS AND IRONS-TEST AND MW 12M
INSPECTIONS

So they seem to make a difference between soldering coppers and
soldering irons. Sadly I can not find 075-190-501 which would possibly
explain it.

One can solder with iron so I suppose it is easily possible there were
really soldering "irons" giving the name, and modern (copper) tips are
still iron plated for long life, but I was surprised to find that the
term soldering copper did actually exist.
