How to Choose the Soldering Irons

Whether you are a novice or a pro, a soldering iron is a must-have.

How to Choose the Best Soldering Irons

As you try to narrow down the possibilities, this section lists down some of the most important considerations.


This is a crucial factor as it is indicative of the performance of the soldering iron. If you are a beginner, you can choose a low-wattage model, especially if you will use it only for small jobs. On the other hand, if you are a pro, then we recommend choosing the highest wattage possible, which is ideal even for the most demanding jobs.

Most of the models available will have anywhere from 20 to 50 watts. A common misconception, especially amongst newbies, is the belief that wattage is equal to power. That is not necessarily the case. Instead, a higher wattage means that the soldering iron will reach the required temperature quicker. If the wattage is too low, you will wait too long, which can affect precision and outcomes.

Temperature Range

Heat is one of the most important properties in a soldering iron, so make sure to consider the temperature range as you decide which to choose. It must reach a temperature high enough to melt the solder. Most of the high-quality models will have a maximum temperature of up to 896 degrees Fahrenheit.

Temperature Control

Aside from the temperature control, you should also look at how the temperature is changed. Some will have a bar that you have to push or pull. Others will have a knob-style dial that you have to rotate. More advanced models will come with a digital display, making it easy to monitor the current temperature of the soldering iron.


It is annoying to work when you have an uncomfortable soldering iron. It must be lightweight and should come with an ergonomic grip. Holding the soldering iron must be easy, which means that it should not easily slip off your hand. We also love ones with a well-balanced design, which will make it easy to hold and control, even for an extended period.


This is especially important for the pros who want to work anytime and anywhere. A good soldering iron is one that is compact and lightweight without compromising its performance. It must easily fit in your toolbox.

Tip Compatibility

If you are looking for versatility, then you should choose a soldering iron that is compatible with different tips. Chisels, bevels, and conical tips are some of the most common tips that must be compatible with a soldering iron.

Electronic repair requires the right tools. Among others, one of the most important is a soldering iron. It fuses conductive elements, such as wires. This hand-held device heats a fusible metal alloy, melts, and bonds.

They are affordable and user-friendly, so anyone can have them. However, with too many options for the best soldering irons, making the right choice isn’t a straightforward task. Read this short buying guide and learn from our recommendations.
