When, during soldering, the tin does not want to stick to the tool, immediately "all the bumps" fly to the soldering iron. Most people think that this is due to the poor quality of the instrument or the presence of defects on it. But in reality, the soldering iron may have nothing to do with it.
Often the heart of the problem lies in the selection of the wrong solder for high temperature brazing. In addition, the reason may be the lack of tinning of the tip. In some cases, an inexperienced shareholder may simply not do the job correctly.
For example, you cannot leave a soldering iron unattended for a long time, as it will overheat. This will lead to burnout of the flux and oxidation of copper. The tip of the tool will be covered with carbon deposits, therefore, the solder will stop sticking to it.
How to work with a soldering iron: tips for beginners
To avoid soldering problems, follow these guidelines:
- 1. Do not overheat the instrument, always unplug it if you do not plan to use it for a while.
- 2. Be sure to dip the tip of the tool in rosin, then the copper will not oxidize, and the tip will not burn out.
- 3. When finished, wipe the sting on a piece of wood. This will help remove traces of flux with solder and get rid of carbon deposits that form during brazing.
If you take into account the tips given above, then you will not even know about many problems during soldering. In the event that the tip of the tool is still burnt, and an oxide layer has formed on it, then the tip needs to be tinned again.
Tips for tinning the tip
Tinning involves coating the tip of a soldering iron with a very thin layer of tin. In this case, both the tool tip and the parts that will be soldered are subjected to tinning. All this is done quickly and easily. The principle is as follows:
- 1. First you need to remove all carbon deposits from the sting. This is done mechanically. As a result, the copper surface of the tip should appear. You can clean carbon deposits with fine sandpaper or a thin file. When cleaning the sting, you need to ensure that the surface is smooth and even, without scratches and grooves.
- 2. After cleaning the sting, it must be covered with rosin. When using solid pine rosin, the sting is heated directly in it until it begins to melt. If a liquid fraction flux is used, then apply it with a small brush.
- 3. When the rosin melts, you need to touch the solder with a sting. If its surface has been thoroughly cleaned, well oiled with rosin, then the tin should immediately melt. The solder can be gently rubbed against a piece of metal or wood.
With proper tinning of the soldering iron, the solder will not drain, but will linger on the tip in the form of droplets. When the tip is close to the workpiece, the tin will separate and will not splatter downwards.
Use the above tips and you won't have any problems with soldering.
