How to Pick the Perfect Butane Soldering Iron

At this point, you’re probably wondering how to choose a solid butane soldering iron. In the section below, we talk about the different features of butane irons and explain why they matter.


Soldering irons are used for a wide range of applications. Whether you’re looking to make connections on a circuit board or want to weld metal jewelry, it’s important to find an iron that boasts an appropriate temperature range.


Most butane soldering irons boast a wattage that ranges between 20 and 60 watts. It’s important that your soldering iron is capable of producing both low and high watts. After all, some delicate jobs require toned-down power, while others require high heat.

As a general rule of thumb, you can use a low-watt soldering iron when working on electric components. Meanwhile, you need an iron with a higher wattage when dealing with automotive repairs and certain metal jewelry materials. Keep in mind that low-wattage irons loose heat faster. When temperatures fluctuate, connections are often inferior. As such, it’s best to opt for an iron that can produce at least 50 watts.


It’s also important that iron gives you detailed control over its temperature output. Most butane soldering irons have a knob that can be turned in order to increase or reduce the amount temperature. It’s important that the control provides accurate and well-regulated control over an iron’s temperature.


Keep in mind that butane soldering irons come with different sets of tips. Many irons boast a variety of narrow and wide-mouthed tips. These tips help shape the flame, making a single iron suitable for both small and large repair applications.

Many butane soldering irons also boast a blowtorch function. Blowtorch functions enable irons to heat up well beyond their conventional soldering temperature. With temperatures soaring well above 2,000 degrees, irons with blowtorch functions can be used to repair leaky pipes, strip paint, and even make creme brulee.

Burn Time

Burn time is a key consideration for users looking to before lengthy operations. While most butane irons are easy to refuel, it helps to plan your soldering time in order to avoid costly interruptions. Most of the soldering irons on our list offer burn times that are 30 minutes or longer. Some of them even boast burn times that are over an hour.

Ignition and Heating Time

Keep an eye out for irons that ignite easily and heat up quickly. With an electrical ignition, it should not take longer than 30 seconds to produce a lucrative flame. Melting time matters too. In fact, most solder melting times max out around a minute.


Butane soldering irons are cordless apparatuses. They are usually pen-shaped and only weigh a few ounces. As such, many people prefer to toss them in their pocket for on-the-spot repairs. For better overall function and comfort, it’s important to look for an iron with an ergonomic design. Slip-resistant grips, strategically placed ignition and temperature knobs, and easy-to-fill fuel tanks all boost the quality of a butane-powered iron. Keep in mind that butane torches can reach temperatures above 2,000 degrees. As such, avoiding contact with the tip is of the utmost importance.


You can never be too safe when working with electronic components, combustible fuel, and high temperatures. As such, we strongly recommend opting for a butane soldering iron with strong safety credentials. Whenever possible, opt for EDS-safe products. These products control the flow of static electricity and, therefore, reduce the possibility of electrical shock.

Why Opt for Butane Soldering Iron?

At this point, you’re probably asking yourself why many people choose butane irons over the electronic alternatives. In general, butane soldering irons offer a greater and more precise range of temperatures. They’re also super easy and inexpensive to refuel. Not to mention, they eliminate cords and other clunky soldering station elements.

The portability of butane soldering irons also makes them a popular choice for individuals working outside or in hard-to-reach places. Without the need for electricity, butane soldering irons allow for hassle-free repairs.

When you consider the lower cost, improved safety, and enhanced control of butane soldering irons, you can easily see why so many consumers choose them over electrical ones.

Best Butane Soldering Irons FAQ

Are butane soldering irons any good?

Gas soldering irons are widely used to solder metal materials together. They are particularly useful in the spheres of electronics and electrical engineering. At the top of the iron, there is a heated soldering tip. Its main task is to melt the solder. After that, you can connect that area by using various ways like hardening, cooling, wetting.

In addition, soldering irons are used for removing and shrinking solder that you no longer plan to use. Quite often you can find soldering irons powered by gas. They are quite effective in desoldering tasks. The soldering iron heat to high degrees. Such temperatures can be generated with the help of electricity and through the combustion of gas. In most cases, consumers use butane gas.

Gas soldering irons allow controlling the flame strengths very easily. There is also plenty of other additional equipment that makes the soldering process easier. It included medicinal air nozzles and soldering tips with separate regulation of the heat. Moreover, a gas soldering iron is used to accomplish various soldering and desoldering tasks.

Among them are soldering electronic components, brazing, joining together copper pipes and gutters, etc. To deal with brazing you need high temperatures. In many cases, devices can be used for fine soldering work with a temperature range of 662-752F. If a hot air nozzle has been installed, you can achieve even higher temperatures. With a flame nozzle, it is possible to reach temperatures of over 1832F without any problems.

Butane soldering iron or electric?

As with the electric soldering iron, the gas models are simple in use. Gas soldering irons are equipped with an igniter and a gas container to maintain the needed temperature. When switched on, the igniter lights the gas and you receive a hot flame.

You can lit many gas soldering irons using a lighter or matches. With the help of a regulator, you adjust the flame you need for soldering. With higher intensity, you receive higher temperatures. One of the main differences between gas models is the gas tank or the amount of gas you can have in it. You should pay attention to this spec while getting one, as it depends on how often you will need to refill the gas tank.

Some gas soldering irons have gas supply installed separately. Using such a model means that you have a permanently attached hose line to deliver gas. This disadvantage makes wireless soldering not possible. Nevertheless, you can connect other gas containers. It greatly increases the time you can operate without worries about the gas tank. Thus you can select between, compact device and a larger one. It all depends on your needs.

What are the dangers of using a propane soldering iron?

Propane gas is an easily explosive substance. Thus, when you use gas soldering irons it is very important to be cautious and work in proper conditions. Containers with propane do not have to be heated or be close to beating devices. By increasing the heat of the tank, you also raise the pressure inside of it. In the end, it can explode.

Why is my butane soldering iron not heating up?

One of the reasons why your soldering iron does not heat up is because of the tip. It may require proper cleaning. After each soldering session, you should clean the soldering tip to remove all unwanted residues. This ensures proper conductivity of the heat across the iron tip and you can easily maintain the needed temperature.

Can I solder with a butane torch?

Blowtorches are usually small, handy propane or butane-operated gas burners, which is why they are also referred to as gas soldering torches or soldering torches. Their primary areas of application are brazing as well as plumbing and heating installations. Moreover, the devices are enjoying a whole range of other possible uses, for example in food making or hobby use. As butane torches can produce high temperatures, you can use them for soldering.
