How powerful should a good soldering iron be?

When choosing a soldering iron, pay attention to its technical parameters. The type of tip is certainly noteworthy as it influences the comfort of work. The tip is a tip that heats up and is used to melt specific elements. Chisel-shaped, pencil-shaped, point-shaped and flat tips are available. A very important parameter is the power of the device. Of course, it should be matched to the type of soldered elements. The higher the power, the higher the temperature of the soldering iron will be. However, if you only intend to solder small electronic parts, a soldering iron with a much lower power will be enough.

Modeco Expert 175W transformer soldering iron For soldering thick cables, it is best to choose a device with at least 100 W. However, a soldering iron for an amateur can have a power of 60 W and will work perfectly well. However, a soldering iron with a power of 100 W is considered to be a universal soldering iron, i.e. one that is suitable for various tasks and is not expensive. Transformer soldering irons enable the connection of larger elements and surfaces. Their advantage is that they heat up very quickly. However, when looking for a resistance soldering iron for home use or for use in a small workshop, you can choose a resistance soldering iron that has a lower power of 40 W to 80 W.

What is the difference between a transformer and a gas soldering iron?

A transformer soldering iron and a gas soldering iron are two different types of soldering tools that differ in the way they work, their energy source, and their applications. For this reason, it is worth finding out what the differences are. A transformer soldering iron is equipped with a wire through which very high current can flow. Its name comes from the fact that the wire is connected directly to the transformer. A transformer soldering iron is best for connecting large elements, e.g. pipes. Moreover, its tip heats up quickly due to the greater power of the device. Its principle of operation is very simple, namely, a high current flows through the soldering tip and heats it strongly. As a result, the soldering iron is ready for use in just a few seconds.

In turn, a gas soldering iron is a device used for joining using the soft soldering method. Tin and tin-lead binders are used here. It can be used for tanning, but also for shrinking heat-shrinkable materials. At the same time, you need to know that it has less power than the transformer type, but greater than the resistance or coil type. Its fuel is butane gas. It can be used for soldering, but also for melting, cutting and even burning wood. It is more precise, but is not suitable for large elements.
