How to extend the life of soldering tips?

A soldering tip is a consumable, but with correct use it lasts months or years. Incorrect handling, on the other hand, can destroy a new tip within days.

Why do tips wear out?

Heat, oxidation and flux attack the iron coating. Once it is breached, the copper core corrodes and the tip no longer takes solder.

The biggest enemy: high temperature

Any unnecessarily high temperature speeds up oxidation. Work at the lowest temperature the joint allows.

Regular tinning

Keep the tip tinned at all times – before breaks and after cleaning. Fresh solder protects against oxidation.

Use the sleep mode

During breaks, activate the sleep mode or switch the station off. This significantly reduces thermal stress.

Clean correctly

Prefer brass wool over a wet sponge – water cools the tip and stresses the coating. See how to clean soldering tips.

Do not use abrasives

Files, sandpaper or knives destroy the coating irreversibly.

Good flux and the right tip

Aggressive flux attacks the tip; a suitable tip works at a lower temperature.

How to recognise a worn tip?

It no longer takes solder, looks black or deformed and transfers heat poorly.

Common mistakes

Too high a temperature, dry storage without solder and cleaning with abrasives. More in the most common soldering mistakes.

Conclusion

With the right temperature, tinning and gentle cleaning, tips last many times longer. Browse soldering tips or find more guides in the ESD Guide.
