How To Tin A Soldering Iron: Guidelines And Tips - SolderingIronGuide

Most soldering irons have a copper tip. As a simple and useful tool, it is applied not only by a specialist but also by handymen who occasionally need to work with electronics. For example, if you need to join two wires or repair a household appliance. However, not all users remember the most important thing – tinning a soldering iron tip.

Why tin a soldering iron tip?

During the soldering process, there is a need to take solder (an alloy of lead and tin) with a heated tip, which is transferred to the joint. But if you do not tin it, then this procedure becomes impossible. The solder does not stick to a soldering iron, respectively, it is impossible to take the right amount of alloy and transfer it to the place of soldering.

Why does it happen? When there is a contact of the heated tip with the solder, this solder melts and adheres to the surface. There is also a layer of tin on it – called a “tin-plated soldering iron”. But if the tip is stained with rosin, flux or plastic, this interaction stops working. The solder simply melts, droplets of metal form, but this tip does not stick as it should be.

A properly tinned soldering iron is a tool when the working part is covered with a thin layer of solder. Tin readily sticks to such a surface, and it can be easily transferred to a conductor, circuit boards, electric components, etc.

Materials for tinning a soldering iron

To properly tin a soldering iron with a copper tip, you need such materials and tools:

• pine rosin;
• solder;
• sandpaper;
• any sponge;

The result will be much better if you follow my recommendations – the experience of 10 years is what I can offer at this point:

1. Do not use a resin that has expired. It is better not to take the darkened and contaminated resin with foreign substances. As a rule, standard rosin is suitable for use within two years after it was manufactured;
2. A solder is recommended to buy one that has the lightest shade. This means that the alloy has more tin, and, respectively, less lead. Such solder melts better and it is easier for a novice user to handle;
3. The sandpaper should be taken to result in no deep furrows left on the copper tip. For the same reason, never use grindstones for tinning the tips. Excellent results are obtained with the use of sandpaper with P150 grit;
4. The sponge for washing dishes must have a hard pad since this side is used in the work. You can replace it with almost any materials. There are also special sponges for cleaning the soldering iron tip;
5. Fireproof soldering iron tips require a delicate attitude. Never clean them with sandpaper, since their protective layer is quite thin. And the damage will lead to early burnout and wear of the tip. Such tips must be occasionally wiped with a special sponge (check the soldering accessories) or on a wet piece of cloth;
6. Instead of a special sponge, a dishwashing sponge is quite suitable. Naturally, the sponge should be moistened with water. You can moisten the sponge with glycerin (sold in all pharmacies), then the sponge will not dry, it always remains wet and ready to work;
7. To clean a non-combustible tip, you will need to use special tip cleaners. It resembles a washcloth made of brass chips in the shape of a ball. From time to time, a person must immerse the tip into this mesh ball. In this case, the excessive solder and oxides from the tip remain inside the ball;

How to tin a soldering iron tip made of copper?

The following method can tin soldering irons only with a copper tip. If you sandpaper the ceramic tip, then it will irretrievably lose its properties, and the expensive nozzle will only have to be discarded.

If the solidified tin remains on the working surface of the tip, then it can be removed as I recommend below. The soldering iron must be heated at first. Then the tip is lowered into the rosin. It is cleaned on a stranded copper wire soaked in flux.
