Why is my soldering tip blue?
Good soldering iron tips are actually plated with metallic iron. Iron does not get dissolved by solder at tin-lead soldering temperatures, so the tips last a long time. What you see is the iron plating oxidizing in air to the blue-black oxide of iron.
Do soldering tips go bad?
Soldering tips wear out over time and eventually need replacing, but taking steps to care for your tips can extend their life, save you money and improve the results of your soldering work.
How do you fix a oxidized soldering tip?
To clean tips oxidized due to using water soluble and “no-clean” fluxes, it is best to flush the tip several times with a rosin-activated, flux-cored solder. This should remove the oxides, unless the oxidation has been allowed to build up excessively.
Can you file down a soldering iron tip?
Never file a soldering tip. Filing it will remove the protective layer, allowing the metal underneath to be eaten away by solder resulting in permanent damage over time. Tin it immediately once it first starts heating up, and every few times you use it as required.
What tip is best for soldering?
Chisel Tips
#1: Chisel Tips Are a Versatile Choice Chisel tips are the most popular tip shape, and they are useful for a wide range of soldering tasks. The wide edge of chisel tips helps them to spread heat uniformly through part leads and pads. The chisel tip is an excellent choice for a variety of applications.
When to use Tinning on soldering iron tips?
The reason soldering iron tips deteriorate is because they oxidize rapidly, and tinning (covering the tip with a thin layer of solder) prevents that from happening. Tinning should be done when you first use a new tip, whenever you start a job, at the completion of a job and regularly during a job, say every three connections.
Why is my soldering iron still generating heat?
If, however, the soldering iron is still generating some heat, the issue is probably the soldering iron tip. When the tip isn’t properly maintained — which is to say kept clean and regularly tinned — oxides will begin to accumulate on the shank’s surface.
What should I do if my solder tip becomes oxidized?
If a tip does become oxidized, flush it several times with a rosin-activated, flux-cored solder. That should remove the oxides unless you have allowed the oxidation to build up excessively. After cleaning, cover the tip surface with a thick coating of solder.
Why do I need to tin my iron tip?
Don’t forget to tin your tip every time you clean it! Flux (a substance that removes oxidization) can help the soldering process by removing the oxidation on the parts being soldered and help the solder to flow. Some solder has flux at its core, but it is also available in paste and liquid form.
