Preparing a New Soldering Iron

  1. Screw on/in a new tip
  2. Heat the iron
  3. Soak the sponge on the soldering iron holder in water. It should be damp, not dripping.
  4. Remember to clean and dry the sponge when done
  5. If possible, use distilled water with the sponge.

"Tinning" the iron

  1. Dab solder onto the tip until the solder 'sticks.' Coat the tip evenly. Wipe off any excess on a damp sponge or rag.
  2. From time to time wipe the tip of the iron on the sponge to remove the dross and excess solder that accumulates during the soldering session. Re-tin as necessary.
  3. If you are using an adjustable base, adjust...

Renovating an Old Iron

Remove any residue on the tip

  • This can be done while the iron is cold or hot. Most soldering tips are plated with iron, filing will remove the iron plating and ruin the tip. Tips will wear out and become pitted with time anyway. The good news is that tips are almost always replaceable and relatively cheap.
  • A knife can also be used to scrape any dross that has accumulated on the tip.

Make sure the tip is firmly screwed in/on to the iron

  • Loosening, then tightening a tip will break any corrosion that has formed and may improve performance in the process. If the iron is hot, use a pair of pliers and keep your fingers away from the hot bits!

Re-tin the tip.

  • Heat the tip, then dab on fresh solder until the tip is shiny with molten solder.

From time to time while soldering, wipe the tip on the sponge to remove the dross (technical term is 'crud') that accumulates in the process

  • A tip cleaning device made from brass turnings is also useful. Electronics suppliers carry these and other accessories.
