Reasons and solutions for insufficient soldering iron temperature
Judging from your description, the soldering iron is the most common kind, it should be the one with no temperature adjustment and low power.
But it feels that the temperature is not enough, which may be related to the object you are soldering. Maybe you are soldering a larger metal object, which dissipates heat quickly, and you will feel that the power of the soldering iron is not enough, and you will not be able to do what you want. The only way to do that is to change to a more powerful soldering iron.
Sometimes it is because the solder you use has a high melting point and is not easy to melt. At this time, you can add a little solder with a low melting point. After the two solders melt together, the melting point will decrease.
Solder itself is an alloy metal. Due to different formulas, the melting point temperature of solder is high or low, and it is used in different welding positions. On fine solder joints, it is often solder with a lower melting point, but in some positions with higher working temperature, For example, high-current solder joints often use high-melting-point solder. So sometimes the larger the pad, it means that the current passing here is also large. In order to prevent the heat generated by the large working current from melting the solder and causing failure, high melting point solder is an inevitable choice.
The electric soldering irons we use now are generally slender and have relatively small thermal inertia. Compared with high-power and strong electric soldering irons, although they can solder solder and have similar temperatures, the high-power ones store more heat and have a larger volume. The thermal inertia of a thick soldering iron is also large, so the type and power of the electric soldering iron to be used is related to what you are using. Only by choosing the right one can you be handy.
How long does a soldering iron heat up
The power of a 60w soldering iron is very high, but the soldering iron generally needs to be preheated for 3-5 minutes. Although you may see it getting hot and smoking, it may not have reached the melting point of solder. The warm-up time of the soldering iron is also related to the use environment. The warm-up time will be longer in an environment with high wind and low temperature. It is recommended to take some protective measures for the soldering iron (such as adding a sleeve) to ensure that the soldering iron can last. Gather heat to reach a certain high temperature.
The new electric soldering iron will have a little smoke and peculiar smell when used for the first time. There is a layer of anti-oxidation paint on the soldering iron, which should be wiped off gently before use. For the first use, the solder should be fully fed to the tip of the soldering iron, so that it can fully absorb the tin and then solder.
