What do you lot use to clean the tips after use? Years ago, I made the mistake of using files which you shouldn't do as that removes the protective coating off the soldering tips so this time around I don't want to ruin my new ones!
I'm not sure I could still solder with the old style hot electric poker. my father was taught to use what was basically a large lump of copper with a handle that he put in the kitchen wood stove to make it hot. He had one big soldering iron and one very big soldering iron. never have worked out why a lump of copper is called a soldering 'iron'. I watched him plenty of times, but it was well beyond my skills......

The old way of cleaning a soldering iron tip was to wipe it on a damp sponge, which is that yellow thing in the soldering iron stand. Some years ago I changed to using what is basically a brass scouring pad. It keeps the tip clean as a whistle, scrapes off excess solder and doesn't affect the tip temperature, or the tip coating.

Mine is made in Japan and came from a local supplier. It looks like this, but I would think the equivalent is available in the UK from electronics suppliers.

Don't be tempted to use a cheap stainless steel scourer from the supermarket, it is hard enough to damage the iron coating on the copper soldering tip. The iron coating is there to stop the copper tip dissolving into the solder.


If you will be soldering whitemetal as well as electrical work, get a separate tip for the lowmelt solder. If the two solders mix, you can get brittle soldered joints.

Regards,
Graeme

Appears to be cheaper in Oz than UK!

There are loads similar to what Graeme mentioned on eBay for under £3 with postage.

Thanks for the suggestion!

Tom, some of those say "steel" rather than the brass which Graeme recommended, and some say 'sponge' without defining.

Our politicians are a bunch of thieves like all of their kind, but not on the scale of that opera buffa in Westminster....... :roll:

There's no import duties in most cases as we don't have any industry left to protect and the GST rate is 10%, not 20% like VAT.
