Buying Guide – What to Look for in a Portable Soldering Iron

Many people are skeptical about portable soldering irons. However, most of these devices offer plenty of power without the need for an electrical outlet. In this section, we’ll discuss which features to look for when shopping for a cordless model.

Source of Power

Cordless soldering irons depend on batteries (either disposable or rechargeable) or butane. How do you know which fuel pack is right for you?

Disposable Batteries

Disposable batteries require regular replacement. Many cordless irons take a set of four AA batteries. One set of batteries may only offer an hour or two of uninterrupted soldering. While disposable batteries can be quite a nuisance, they also enable users to finish a soldering job with minimal interruptions.

Rechargeable Batteries

Rechargeable batteries will also spare you from having to seek out an electrical outlet. Lithium-ion batteries tend to offer lengthy power cycles with limited power. Fortunately, these batteries can be recharged after each session. As such, you won’t have to worry about stocking up on disposables. It helps if an iron features a power level indicator.

Butane

Butane is an affordable fuel source. If you opt for a butane-powered soldering iron, be prepared to handle a hot flame and free-flying sparks. What’s more, make sure that the iron has a fuel tank with a large capacity. Otherwise, you’ll spend half your soldering session refueling.

Temperature

Most solder has a melting point just below 400 degrees. A soldering iron needs to be even hotter than that if you want it to produce joints in a reasonable timeframe. Soldering irons with adjustable temperature dials offer users the most control over their output.

Operating Time

While cordless irons are extremely versatile, they also boast a limited lifespan. Make sure that your iron is capable of performing long, tedious tasks.

Ergonomics

Both corded and portable irons should boast comfortable, non-slip grips and triggers. A proper grip can prevent unpleasant accidents. Make sure that you can perform most maneuvers with one hand.

Accessories

Ensure that your iron comes with quality tips. Soldering iron tips come in a variety of shapes and sizes. Some soldering irons come with kits that include replacement tips and tools for soldering tip removal.

Keep in mind that most cordless soldering irons require fuel. Make sure you are comfortable stocking up on AA batteries or bulk butane. The only exception to this rule is rechargeable irons that include a lithium-ion battery. Finally, be aware that products advertised as bare tools do not come with a battery.

Many irons also feature user-friendly elements, such as LED lights and toolless tip removers. Elements such as these can have a dramatic effect on your soldering experience. Always be on the lookout for small improvements that make a big difference. Sometimes these elements are the only thing that sets a soldering iron apart from the competition.

FAQ Cordless Soldering Irons

What is the best cordless soldering iron?

Cordless soldering irons are quick to use, convenient, stylish and cost about the same as a soldering gun of decent quality. There are hundreds of electric and gas cordless soldering irons. The most reputable manufacturers have lineups of cordless soldering irons – think of Weller (BL60MP), Milwaukee Electric Tools (M12), Levixon, Hakko (FX-901/P)

Things to consider when picking a cordless soldering iron: 

  • Power source. Cordless soldering irons are mostly powered by batteries or butane. The better alternative is a Li-ion battery-powered device because fuel is more expensive;
  • Run time. The second most significant factor that you’d think is the iron’s overall run period. The majority of modern cordless irons provide a run time of approximately 40 minutes or so. Yet high-powered (butane) computers can also have a higher operating time;
  • Accessories. Cordless irons often come with a few attachments. The LED focused light for better readouts  in dark areas is one of the most influential accessories they come with;

How should you use a cordless soldering iron?

Where there is a shortage of electricity supply to use a basic iron, cordless soldering irons are required. In addition to repairing electrical equipment and constructing circuit boards, these handy methods are applied for creating jewelry and art designs. The operating temperature of these irons is not explicitly regulated; by altering the gas flow, gas irons may alter power setups.

Gas-powered irons can have interchangeable tips for applications such as shrinking heat shrink tubing, miniature blowtorches with a hot flame option, a hot knife for cutting plastics, and tiny hot air blowers.

But despite all the pros of cordless soldering irons, these devices can only be used as auxiliary tools for hobbyists and DIYers. These low-power irons are mostly used in the jewelry industry, dentistry and other niches where portability and precise soldering are required. Also, such irons can be recommended for soldering wires in vehicles. 

Are battery-powered soldering irons good?

A premium cordless soldering iron can become a perfect solution when your soldering project demands maneuverability. All the electric models are powered by batteries (usually lithium-ion), whereas fuel-based models burn butane to produce enough heat for constant melting temperature. 

Why should you invest in battery-powered soldering irons: 

  • It may also be found in vehicles without a power supply or in plants where it is difficult to use gas-type gadgets;
  • Portable and lightweight;
  • Soldering may be achieved with a few inexpensive AA batteries at any time. You may still use rechargeable batteries because they are economical;
  • With an LED on the front, they can illuminate every project brightly; 
  • Can reach the melting temperature up to 600-700F in a few seconds. When new batteries are applied, you will operate immediately;
  • It is secure to hold because the switch is secured with a cap;

In the case of cordless iron driven by batteries, the issue is energy and heat. With certain models lasting just minutes, batteries will die mighty soon. In comparison, the iron rarely gets just as hot as you plug in anything. That is why such devices can be recommended for simple projects on the go. 

Are butane soldering irons good?

The power for melting the solder falls from the burning of butane gas while a compact butane iron is applied for soldering. Butane-powered irons are compact and can be shipped and used in places where there is no energy. They are often easy to refuel and the individual heat ranges or chords do not place any limits. Butane-powered soldering irons offer a number of other advantages:

  • Many sources of energy/power. The refillable butane gas tanks (or battery packs) may be applied as a power supply for heating the tip. Lightweight butane soldering iron. By regulating the gas flow, the temperature of the tip can be regulated;
  • Versatile. Many conventional butane driven irons often come with modification features such that the soldering iron can be mounted to several different shapes, forms, and tip sizes. A variety of steps may also be done and various tasks may be achieved by a standard soldering iron;
  • Good for beginners. There are several situations where the power cord trail will not be appropriate for the scenario. The butane-powered iron has quick access and can enter the most challenging and remote places. They also operate in places where (permanent or temporary) power is not available;
  • The butane fuel is quite cheap. The refilling of solder iron with butane gas is very cost-effective. Butane is a gas that is very cheap and readily accessible, and can also be obtained at good savings when you call reliable retailers to buy a soldering iron;
  • Heat up quickly. As butane-powered ions are used the soldering phase is completed in less time. For an urgent power supply, the quick combustion of the gas provides and a butane-powered iron can’t require more than 10 seconds to be prepared for soldering;

Most specialized (and expensive) butane-powered irons often come with additional features, like snap-on tips, stands, sponge cleaning and many more. To make a safe and trustworthy order, call a trusted retailer when you want to purchase a welding iron.

How should you solder properly?

To use a cordless soldering iron you should follow such steps: 

  • Heat the attachment for a couple of seconds with the tip of the soldering iron, then add a solder product. The tip should heat, not the solder paste;
  • Keep the soldering iron at the base of the handle like a pen;
  • To build a good solder joint, both sections that are being welded must be hot;

New soldering iron tips appear to have unique coatings, which is beneficial since they resist oxidizing. This coated layer is the reason you can never file or sand your tip to clean it because the tip will be worn out very soon.

What temperature should you set your cordless soldering iron to?

Taking enough time to plan before soldering will eliminate errors that might potentially become a health threat. This is why it is necessary to suggest choosing the proper soldering temperatures and choosing your soldering iron.

Much of the solder’s melting point relies on the alloy composition. About 355-375F, lead soldiers usually melt. There is also a precise melting point of certain ‘eutectic’ alloys. However, since 2006 the usage of lead-based solders has been universally prohibited in the commercial sector because lead is harmful, collects in the body for a prolonged period and can be removed only very slowly.

There is a greater melting point when it comes to lead-free alloys. However most lead-free solder products only have the melting drawback of 420F and beyond. This suggests that there has to be a much greater heat production for the soldering iron. And the hotter the iron’s tip, the greater the chance of your fingertips burning when caution is not taken. In comparison, you will overheat the components even more readily if you keep the iron tip in one position for too long.

Most manufacturers provide the maximum temperature range that their cordless soldering irons can reach. For instance, Weller Pyropen WP 60 has a temperature range from 930 to 2370F. While Weller WHS MC iron has a limited temperature range from 210 to 750F.

  1. A cordless soldering iron is considerable if one needs exceptional performance. M12 Soldering Iron is the best soldering iron to me as it heats very quickly as well as maintains a stable and optimized temperature which is an essential criterion for sure.

  2. Interesting Blog but you missed some of the best battery operated irons ever made. They have been on the market for many years and use a different technology than the ones you have tested. One of the basic concerns with any iron on a PC board is isolating the current surge so as not to take out any components while soldering. You might want to take a look at the Iso-Tip hand held soldering irons from Senasys. They are a complete different animal and they are currently upgrading their complete product line. They have a crazy fast heat up (10 sec.) and a large number of tip styles. They are a much different product than the ones you have tested and I think you will be pleasantly surprised at the performance difference. They are a professional tool and have been used by the military in aviation since 1970 I believe. They have also been a standard for production lines. The name Iso-Tip comes from the isolated tip design which protects from component damage during soldering and the tip design is completely different from the ones tested.
