Factors to Consider

There are several important factors to consider before you decide to buy. It’s important to consider all of your requirements, so you purchase a good soldering iron.

For starters, you should take into consideration the wattage of the soldering iron/station. Most irons that are used for electronics are between 20 and 60W. One of the most popular soldering irons is the one with 50W because this model provides enough heat for most soldering projects on the circuit boards. Usually, the higher the wattage, the better a soldering iron is. But if a product features higher wattage, this does not necessarily mean that it will also apply more heat to the solder joint; it just means that the tool has increased power available. A soldering iron with low wattage, 20 to 30W, will lose heat much faster than it is able to re-heat itself and this will result in poorly made solder joints.

Another essential factor to be considered before purchasing your soldering iron is the type of tool that you will need. There are four main types of soldering irons: soldering pencils, soldering stations, soldering systems and soldering guns.

Soldering pencils

Usually very simply constructed and it is used for easy projects. They don’t provide temperature control, and this is important because when you apply too much heat during the soldering process, you can damage the components on the circuit board.

Soldering stations

include a soldering pencil attached to a power station. The power station provides you controls for setting the appropriate temperature. Some stations come with electronic temperature control and they automatically keep the iron tip at the best temperature.

Soldering systems

also known as rework/repair systems are more complex soldering tools and they are mostly used in the industry or the manufacturing facilities with high volume. A soldering system includes a few handpieces such as a soldering iron, a hot air gun, a de-soldering gun, thermos-tweezers and so on.

Soldering guns

are transformers that convert 110 V AC to a much lower voltage. These tools can be quickly turned on and off, and they feature a short warm-up time.

It’s worth mentioning also that if you’re anything like me, then you probably have a ton of tools lying around creating a mess. That’s why it’s a good idea for you to get some kind of storage to help organize your tools. Here’s a guide written by our friends to help you choose a tool chest or tool box to store everything in.

Temperature control is the last crucial element to be considered before buying a soldering iron. Most soldering tools come with three basic temperature designs. Soldering irons with no temperature control – and these are used for household basic soldering projects. The temperature-controlled soldering iron – which will allow you to make sure that the soldering iron’s tip keeps its appropriate temperature. The third temperature design is used by the soldering stations that usually offer digital temperature readouts and adjustable iron temperature among more handy features. The best soldering iron for your individual case should strike a balance for the performance you need, and your budget.



Accessories Guide

While some soldering kits come with all that you’ll need to get started, you might want to consider purchasing some accessories to complement your setup. Even with the best soldering iron it’s great to have some additional tools. Some accessories are optional add-ons, and others are necessary to get anything done! So let’s take a closer look. On a side note if you’re looking for technology for better purchasing decisions be sure to read some good tech reviews.


Soldering iron tip cleaner – steel wool

To clean the tip of your soldering iron, it’s a great idea to have some steel wool. You can purchase specifically built steel wool tip cleaners from Amazon. Another option is to use a sponge, preferably wet. However – steel wool is generally more effective.




In order to make any use of a soldering iron you will need some solder! There are a few options to choose from so let’s take a more detailed look. You could use leaded solder, which has the benefit of being easier to use. This is because it’s melting temperature is lower.

However most people prefer lead-free solder for health and safety reasons.

Another question to consider is what size of solder wire you will need. In most cases anything between 0.7mm and 1.6mm is fine. Larger solder lasts longer but lacks the level of precision that you have with the smaller wire. For the average user, and the beginner we would recommend 1mm solder. It has a good level of precision while not compromising on ease of use.



Soldering Helping Hand (Third Hand)

We only have two hands, and sometimes that isn’t enough. It’s a great idea to get a tool called a “third hand”. This tool is used when you need to hold two or more components together AND hold your soldering iron. It works by using alligator clips to grasp the work-piece. This add-on is cheap and honestly makes the task so much easier, so it’s definitely a worthwhile purchase.



Soldering Basics


Are you sick of spending money on brand new charger cables, phones, and TVs when they go bad? You don’t have to break the bank to keep your life functional. With just one little tool, some time, patience, and practice you can repair all of these things yourself!

What kind of tool can repair countless everyday staples and even improve them? A soldering iron. At some point, you’ve probably seen one in a DIY project or on the desk of your computer repair tech. For most people, it’s something that no one thinks about until it’s needed. They are one of the most underrated hand tools! The main problem is that a lot of people don’t know how to use a soldering iron.

After a little bit of practice, you’ll wonder why you never had one before! Before you run out and buy one, be sure to check our reviews above.

If you want to learn how to use Soldering Iron – don’t worry, we have you covered! Although it’s a fairly simple process, it will still take some practice. The main thing is to not overthink it! Just follow these instructions:

  • Allow the iron to fully heat up
  • Use a wet sponge to clean the tip of old solder
  • Keep the sponge handy!
  • “Tin” the tip (use a small amount of solder to coat the tip)
  • Do this after every few joints
  • Hold the iron in one hand and a long piece of solder in the other
  • Touch the iron to where the two pieces will join for one second
  • Slide the solder under the iron then hold for another few seconds
  • Pull the solder away first
  • Then after about 3-5 more seconds, remove the iron
  • Let the solder rest

There you go – now get to practicing! You’ll learn how to use the soldering iron to make jewelry, make your phone charge quicker, and much more! There’s so much you can do. However, since soldering irons get so hot, there are a few things you should keep in mind.

Important Things to Remember

You’re well on your way to a plethora of home repairs and upgrades! Even after you are well-versed in the flow of the solder, there are safety precautions that beginners and experts alike should follow:

  • Solder comes in different widths and types. Make sure you buy the right one for your project.
  • Practice soldering with materials you don’t care to waste
  • Or practice with DIY beginner soldering kits!
  • Do not leave the room with your soldering iron on
  • Do not touch the hot end of the iron
  • Use pliers to handle other components that may still be hot
  • A proper solder should be smooth, shiny, and touch both components
  • Improper solders will look grey, dull, grainy, or like a wad of foil
  • Don’t apply the iron for a long time. The excess heat can damage materials

With these simple safety rules in mind, you can learn a new skill that will expand your creative side. Once you get started, you’ll surprise yourself at what you can mend, create, and upgrade. What are you waiting for?
