Seems like drawing enough current to melt a plug should've blown a
fuse first.  UNLESS ... the contacts were already failing.

Then as a contact jiggles & becomes a higher resistance, it will heat up
(assuming sufficient current) and create oxides covering the contact
surfaces (these aren't high quality gold).  That's the beginning of the
end for that plug/socket unless someone realizes what's happening and
cleans it up before melting or burning takes place.

*** Suggest trying to preform the contacts (if possible) to make sure
there's plenty of contact pressure, no matter how sloppy the fit.
