[Markus] was looking to upgrade his soldering station, and having had good luck with Ersa in the past, opted to purchase one of their new stations, the RDS 80.
Once he got the iron home however, he was very disappointed to see that while his previous Ersa model used a silicone cable to connect the iron to the base station, his new iron used a stiff, non heat-resistant PVC cable instead. He found plenty of people complaining about the same issue online, but no one seemed to have a fix, so he set off to figure it out for himself.
He thought that he could disassemble the iron and change the wiring out once it was apart, but it seemed that there was no way of doing so without destroying it. Instead he chopped the wire off at the end of the soldering iron, replacing it with a new silicone cable. He did the same thing at the base station end, since he was forced to reuse the proprietary 4-pin plug Ersa decided to use there.
His modifications worked out nicely, and he is now happily soldering away.
If you happen to have one of these soldering stations, be sure to swing by his site to get a closer look at how he swapped out the cable.
