There are different units.
There is a WTCP 51 for European 230VAC and the schematic is shown above.
There is also P51 power unit with 110/220 selector switch for US market, no schematic to be found.

Thank you man. You don't need to go to the trouble of getting the schematic for me but it is greatly appreciated.

I live in Ireland. The European unit works for me.

No problem. This what we do on AAC when under lockdown and bored.

I believe it is the correct schematic

 

I believe it is the correct schematic

It is 95% correct. It does not show the voltage selection switch.
If the switch is faulty and causing a short to the 110 setting then it could blow the fuse.

 

Important
Do not change the 110/220 voltage switch setting until you have taken a resistance measurement at the power prongs.

OP has already stated that the fuse doesn't blow if the iron isn't attached.

When I turn on the station woth the iron unplugged it stays on. However when I plug the iron into the station the fuse blows straight away.

 

I believe I have found the solution. Since it is an old iron, the insulation on the wires for the iron were completely worn and broken down. They were shorting the circuit.

That's odd. My main iron is over 40 years old and the cord doesn't get much abuse.

With no load on the step down transformer the setting of the 110/220 switch doesn't matter. The fuse should not blow.
If the switch is set to 110 the fuse should blow with the heater element load on the transformer.

Yes it is odd. However this iron was used for years in a industrial setting.

It's a good iron when you take care of it.

When my heating element burned out, I bought two similar units to make sure I'll always have one.

 

I would certainly inspect the patch on the cable because it does not bulge enough to be an adequately insulated splice. The fuses were working perfectly in protecting against damage to other parts. A dmaged cable is the most likely problem and not that hard to repair.
Good luck!
