Replacing the Maplin N78AR solder station Iron

One of the first things I bough when got to Ireland, three years ago, was a soldering station.

...Well it's not technically a solder station it's more of a soldering iron stand with some control on the iron power. Similar to a light bulb dim circuit.

In last few weeks the soldering tip was getting completely destroyed, normal after 3 years of intense soldering, I went to replace just to find out the retaining nut was completely stuck and in the process I broke the internal heating element.

Since there was no spare irons on sale for the station model, went online and spoted a vey similar one, tough less powerfull, 30w, the standard is 50w.
My guess it's the same manufacturer and then re-branded.

On the left is the new one... by this time I had removed the cable from the old one to prevent any accidental connection since internally the heating element wire was broken.

Replacing was just a matter of connecting the new soldering iron cables.

I reused the stress release rubber from the old cable
 The station has a retaining slot for the stress rubber, nice build touch.

Since I only have one working soldering iron could not solder the contacts of itself (I could but not safe to do), so they were very well wrapped and isolated.

The internal control circuit is a very simple one so no change was needed.

To open the "station", remove the 4 screws bellow the rubber feet.
Overall I find it well build. For the price and if you don't need anything fancy it can't go wrong.

Now I can go back to melt some solder.

Have a nice week!
