Title: Soldering
Post by: Josiebenn on January 22, 2019, 06:48:12 PM
Ok, Iíve learnt late that my iron should be tinned.   So, looking for instructions I discover a YT vid, which tells me to use Plumbers Paste, but the word FLUX was visible on the pot in use.    Which leads me straight in confusion.  I have Soldering Flux and I have coreless solder. 

Are there important differences?  Have I got the right or wrong stuff to tin the point?

Unless you're using low temperature solder (for white metal) ordinary lead tin cored solder should be fine for tinning your iron and most of the soldering you will encounter.

Lead free electronic solder.  Regular soldering flux paste.  Still beading,  not coating.  Tried cleaning with steel wool.  Didnít work.   Copying actions in YT vids, but no success.

Another thing... Use a sponge dampened with water to clean the soldering iron tip after each soldering operation.  :beers:

Best to avoid lead free solder in my opinion for the type of solder work we use.
Stick with standard lead tin.  :beers:

Thanks Bob, but as I said above, still beading, and the tip is now discoloured.
Next step?  I was amazed how difficult it was to find a roll of solder at all!   Took,
what I could find, not knowing any better. And £11 squid is not small change. 

Is my blackened tip rescue-able?

If you can't clean it with water and a sponge (with the tip hot) then probably best to get a new tip. Sandpaper or emery might buy you a few joints but will take the plating off the tip.
You can get resin cored lead tin solder online from Rapid Electronics, RS Components or Farnell.  :beers:

Thank you, Bob, even though frustrating to be in this position, with late learned information. 
Back to Farnells.
