Solon soldering iron

My usual soldering iron failed over the weekend so I dug out a Henly Solon 25W iron which I bought as used/new some years ago. Sadly this also failed after about 10 minutes work on electronic components. When I stripped it down the heating element seemed to have suffered a partial disintegration. Working on the principle that I have never had anything but a positive response from the members of this site, I thought it worth asking whether Solon spares are available at possibly some remote outpost ?

Hi Mick I would have thought that a soldering iron of that age would have used a simple nichrome wire element and there are a few seller's on the net. You would just have to measure the wire gauge and order to suit.

£7.99 for a 25watt Henly. on ebay !

Ridiculous nostalgia really, I suppose, but this iron has not been used and is identical to one I had when I was about twelve years old. There are probably better items on the market but nostalgia strikes again. Maybe I will have a look at a different nichrome wire element as David suggests. Thanks for the help.

Can you still buy "Savbit" copper bearing solder to stop the bit disolving?

P.S: To answer my own question, CPC list it and it is still a tin/lead alloy.

I don't know how many Solon irons I got through. Horrible tat - had some at home, used others in development labs on holiday jobs. When I started working after graduating I discovered Weller irons, what a revelation. Frankly I'd just buy a proper modern iron.

One advantage of the larger Solon irons was the heat capacity of the massive bits - and if the 65W job I used to use was not hot enough it nicely fitted through the grill of the 2 bar electric fire to get a bit of extra warmth!

I still use the 65W Solon that dad bought before WW2 when he was doing radio repairs. I think it is all origional, tip and element. For larger work I have a 175W Weller. When I got the Weller the tip was badly eroded A new tip was going to be $NZ80, so I wen't and saw my metal supply man and bought a piece of 20 mm copper, I think it was 100 mm long. I have a pair of old copper soldering bits, about 2lb each, which each heat quickly on a gas ring.

I refer the honourable gentlemen to the Henley Solon Owners Club, started in the pages of Club News. There are a multitude (3) of enthusiasts/obsessives, membership is free, and you get nothing for it. (Unless, of course, you have spare parts to help the afflicted above)

One interesting failure mode I experienced more than once. Handle was in two parts with a horizontal split line, moulded from some sort of Bakelite material. The part of the handle nearest the element tended to get quite hot and the plastic degrade, to the point that one day when you were pressing the bit against a terminal part of one half of the moulding would fracture along a moulding feature and the entire hot element part become detached, apart from the live wires. Exciting!

I think that the old Solon elements were insulated with asbestos, so you might want to take care with the debris of a disintegrated one.

I just bought a soldering station from Lidl. I think it was £6.99 Controller + holder. Even has some reels of solder with it.

Hi, I didn't find any asbestos in this old 250W Solon iron. The element is wound on Mica sheet and Mica sheets separate the two elements from each other with two narrower thin iron plates in the middle and Mica sheets insulated the elements on the outside, the whole assemble then fitted into the slot of the copper bit.

The outside Mica sheets just fell to bits during disassemble. Wont bother to try and fix this one, but might mount the copper bit onto a piece of steel and heat it in a flame, maybe one day.
