Best Cordless Soldering Iron Buyers’ Guide 

Choosing the best cordless soldering iron can be a daunting task, especially when you do not have prior experience with the machine. This is primarily a challenge with the butane-powered models. However, in this guide, I have listed the primary factors that you need to consider before you make a purchase decision.

These factors aim to ensure you get a model with the best heating source and that which will give you both the comfort and longer run time.

Heat Source

The heat source is perhaps the most practical consideration when buying the best cordless soldering iron. The heat source can be butane, electrical, or the model can be battery-powered.

Traditionally, soldering guns used electricity as a source of heat. However, the demerit of this source is that it grounds you to a single workstation as you must plug in the tool to the socket or connect to the electric source for use. This leaves butane and battery-powered models as the most ideal.

Butane as the heat source is one of the most affordable fuel sources, and it is preferred for professional heavy hitter DIY enthusiasts. The butane irons have an advantage that they get hot faster and are portable as the models are self- ignited, but they can be too hot for some applications.

A person with no prior experience with the butane powered machines may not adequately handle the heat and sparks that come out of these models. Also, the models need constant refueling, and the combustion of the butane, a carbon compound, can result in the release of carbon gases, which are pollutants to the environment.

The battery-powered models are thus the most effective models because there are no codes required and, therefore, portable. The battery-powered units are also eco-friendly and provide just the same power levels as with the electric and gas-powered models without getting too hot for the delicate electronics.

When buying the battery-powered models. You have two choices; you can purchase the units with disposable batteries or the one with rechargeable batteries.

Most of the cordless soldering irons run on disposable AA batteries. A single set of these batteries will offer you an interrupted run of between 1 and 2 hours of service. This is an impressive run for the DIY projects that you might be involved in both at home and in your work stations. The advantage with such models is that these batteries are cheap, but it can be tedious when your work is extended, and you have to replace them every time the batteries run out.

The second set is the rechargeable batteries. Such units will demand that you have an electrical outlet. Such models use lithium-ion batteries that have several merits, including lightweight, compact design, and a longer run time before they get recharged.

Even though these units will cost you a bit more due to the nature of the batteries used, they will give you the longest run time you require for extended usage. Most of these models also come with power level indicators that will show you when they are due for recharge, and this helps prevent work breakdown.

Thus, when buying the cordless soldering irons, consider the battery-powered models because they are environment-friendly and do not get too hot for the delicate electronics or require cords to operate and thus more portable. The lithium-ion or nickel batteries used in these models also produce high power and, therefore, a longer run time just like with the electronic models.

Temperature Control

When choosing the best cordless soldering iron, temperature control is a factor that you must consider. You will require a temperature adjustment system from higher to lower and vice-versa for different applications. 

The variation of temperature will give you more control and the versatility to take on a variety of projects since you will be sure not to damage the delicate components due to overheating or not using low temperatures for high-temperature projects.

Comfort

 The comfort when using any tool is an essential element that you must consider. You must find a soldering iron that provides an ergonomic design that will not cause you much fatigue, especially when you are planning to work on projects for a long time. 

In that case, you must go for a soldering iron fitted with a stand that will permit you to set the iron down and take breaks to keep your hands from cramping and this will give you the needed comfort when operating models with longer run time.

Run time 

The running time of the unit you are purchasing is also an essential element of consideration.  Compared to the corded counterparts, the cordless models give a relatively shorter run time. 

For the cordless models, the runtime always ranges between 30 minutes to a couple of hours. However, this is also dependent on the type of fuel you will use in the machine.

The units using butane give a longer run time of between 1 and 2 hours before you refill the tanks. However, these models will require you to refill the machine whenever it runs out continually, and the butane gas may not be readily available. It might result in some hassle that can be monotonous or time-consuming.

 The battery-powered models provide you with a run time of between 30 minutes and 2 hours. However, this is based on the type of battery used in your model. The rechargeable batteries will give you a longer run time than the disposable ones. 

Accessories 

The accessories that come with the cordless soldering guns are quite impressive as they improve both your work and the working area. As much as some are considered aesthetics, they are undoubtedly essential to enhance the ease of work and convenience.

One of the most vital accessories that come with these models is the LED focus light. The LED system offers focused beams of light to illuminate your working area since the table lights can cause the shadow on the work area, inhibiting your visibility.  

Other accessories include a free solder, brush, or other packages that come with the batteries. In some cases, depending on the type of job you need to execute, you may prefer to have a kit with free soldering tips.

 The accessories may also include spanners, wrenches, brushes, and other small tools to help improve your soldering job. 

The below picture show some of the accessories available in the Demel 2000-01 VersaTip Precision Butane Torch Soldering Iron package.

Safety Measures When Using Cordless Soldering Iron 

Your safety should be a priority when using any machine. The primary worry with the people who have not used a soldering gun is always burning or damaging the whole unit, especially when you did not consider the construction material at the time of purchase.

The fear of the burns is always ideal as these models get very hot, and when not handled carefully can pose a danger to yourself. However, to limit such risks, always ensure you put on protective clothing such as gloves, safety glasses, and loose clothing and hair out of the way. You should also ensure you are careful with your fingers. 

Moreover, solder can contain lead. Be sure that you clean your hands before handling it. As a practice, you should normalize working in well-ventilated spaces or workstations since the fumes from the rosins can be a threat to your breathing system; the rosins can damage your lungs when inhaled.

It is thus essential that you take the needed precautions. Most of these safety measures are common and, when applied, can save significant time from such injuries and unwarranted damages.

How and Why the Soldering Tip should be cleaned before use 

Proper heat conduction is an essential process that ensures convenient and easy soldering. However, you must ensure that your soldering iron is free from any old solder for efficient heat conduction. 

Iron quickly oxidizes when left exposed to air. Once oxidized, the metal will insulate against heat and become a poor heat conductor. You need the heat to be efficiently conducted in your device so that the model can attain the melting temperature within the shortest time possible for rapid and easy soldering. 

Moreover, the tip should be clean as a dirty tip holds the iron longer and risks heat damage to the PCB, and this can be costly. The tip can get cleaned with a wet sponge.

You should ensure that you keep a damp sponge handy, and after soldering iron is fully heated, you should softly scrape it against the sponge to help remove the older solder. This should be done until the tip becomes shiny. 

Tinning the Tip

Tinning refers to the process of thinly coating sheets of wrought iron with tin. It involves coating the metal with the solder before soldering. The practice aims to protect the tip and allow for better heat conduction through the new solder.

The process involves carefully applying small amounts of fresh solder and coating the tip. Immediately you have tin the tip; you need to begin soldering before it gets oxidized again. The process should continue after every few joins. You need to clean and re-tin the tip. This should also be done before you store the soldering iron. 

The process not only facilitates the efficiency and convenience of your work but also enhances your tool’s longevity.

The video below shows how you can clean and re-tin the soldering tip

Conclusion 

The best cordless soldering iron can help you conveniently and effectively join crucial components, and it is quite versatile. With the soldering irons, you can impressively work on anytime and anywhere as they are compact and lightweight hence portable. 

Also, the wide range of heat provided by the soldering irons ensures that you can solder multiple items without any obstacles that can arise due to the entanglement of the cords. 

In this guide, I have reviewed some of the best cordless irons, which are efficient and of high-quality to limit your search. Also, I have provided a buyers’ guide to help you make the best purchase decision and realize the value for your money.
