I use Weller tools, too.I tried cleaning them with all sorts of stuff from sponge to steel-wool to brass wire brush and eventually sanding paper.
I did not notice that the iron is too hot while soldering but it could still be a problem.
The TCP-01 has its thermostat inside the handle, it uses the magnet Curie point to release a spring loaded switch when temperature is reached. It is very efficient because it monitors the tip temperature rather than the barrel temperature.If it is consistently overheating, then the base unit needs attention.

The tip should have a number stamped at its blunt end, '7' for normal soldering. If the thermostat is sticking, which is probably the main failure mechanism on that model, I fixed one once by opening the switch and cleaning the contacts then wiring it so that instead of cutting the current to the element, it broke the connection between the earthed barrel/tip and the floating element. The element was permanently connected in the handle. I then built a small triac control board inside the base and controlled it by looking for continuity between the element and earth paths. It kept an otherwise faulty iron working for years afterwards and I think it is still here among the cobwebs somewhere.

Check the spring is in place beneath the thermostat, it keeps the element 'pushed up' to the tip but if slipped or missing, it may not see the magnetic field from the tip and assume the wrong temperature.

Cheaper tips do not have the required thickness of iron plating...
Is that iron plated on a copper core or copper plated on a iron core? I thought it is the latter. Iron is not wetted by solder.
iron will not go into solution with "real" solder ( tin/lead ) but you will lose it to the non lead solders ...
Gas anyone tried that stuff in the second video?
Using the damp sponge to clean often, helps. But
mostly this:
(a hard rosin w/ tinning, perhaps similar to plumber's
tinning flux but not acidic)
