Ersa RDS80 is a great soldering station for hobby use, that offers a lot for an affordable price. But it has one weakness - an unappropriate cable for the soldering iron. It is neither heat resistant nor flexible. After using the soldering station for two years, I decided it was time to change the cable.
Although the connector on the soldering station has 4 contacts, only 3 of them are used and the cable has three wires. So I bought a silicon cable in Conrad (nr. 604365) and started with the repair.
The soldering iron itself can not be taken apart, so I just cut the old cable and soldered the new one. On the station’s side is a standard DIN-4 connector. Because my local supplier did not have that connector I used DIN-3 connector and replaced the socket as well.
Now for the hard part. First make sure you have a secondary soldering iron, that you are going to use to solder the cable on ERSA soldering iron.
First remove the cable protection from the soldering iron:
We have to insulate the wires and put on the cable protection. Now we have the super ERSA with silicon cable.
