Gas-powered soldering irons are your go-to alternatives when looking for portable and cordless irons. They are excellent for making quick repairs and working on hard-to-reach areas. Gas-powered irons are also suitable for making repairs that don’t require plugging in electric soldering iron and waiting for it to heat up to a suitable operating temperature.

They are powered by refillable butane gas,which burns to heat the tip. The temperature of gas-powered irons can’tbe controlled directly, but users can control the flow of gas toregulate the heat settings.

Since the fuel contacts the parts you are soldering directly, the iron heatsup fast, saving you the time. You can also refill the irons usingregular cigarette lighter aerosols.

How Gas-powered Soldering Irons Work

The design of the iron determines how the gas ignites. Some irons heat upwithin a short period during which a catalyst burns, and the tip heatsup. Other designs require the user to press a switch that extinguishesthe naked flame, triggering the catalytic heating process, which heatsthe tip.

The irons rely on a catalyst to heat just as butane-powered tongs and haircurlers. When the butane gas is ignited, the catalyst burns in thepreliminary stage as unburnt butane gas continues to pass over a hotcatalytic element that fuels the burning action to produce temperature.

High-quality gas soldering irons should have a range of tips that make the iron aversatile hand tool for DIY or different electronic applications. Someirons are built with catalysts on every tip, while others use onecatalyst for fitting an appropriate working tip.

The latter is ideal for making occasional repairs and for hobbyists.However, once the catalyst gets damaged, the entire iron is rendereduseless. Irons with built-in catalysts for each tip, on the other hand,are more expensive.

Why Choose Gas Soldering Irons

Extensive Range of Heat Settings

Gas-powered irons provide a broader heat range compared to electric soldering irons because you can control the amount of gas burned when soldering.

This results in a lower level of heat, energy efficiency and the ability tosolder without over-doing it. Most butane irons deliver a range fbetween 25-75 watts depending on the amount of butane you burn.


Gas-powered soldering irons are excellent for soldering inaccessible areas as theydon’t need an electrical source. As such, you can bring them outdoors;use them in buildings that don’t have electricity or areas where themain power supply is unavailable.


Electric soldering irons require a few minutes to set up and heat up whilegas-fueled irons are ready to go right away, letting you perform thetask fast.


Gas-powered soldering irons are lighter and less bulky than electric irons. Assuch, you don’t have to deal with the annoying tangled cords and wiringproblems electric soldering irons are prone to.


Gas-powered soldering irons have become popular as more companies release different versions. Some reputable brands include the classic Weller, Wall Lenk,Iso-Tip, and Blazer.

Affordable Refills

Gas-powered soldering irons use butane, which is relatively affordable. What’smore, butane refills can be bought in bulk, and some retailers offerdiscounts.


Gas-powered soldering irons kits have interchangeable tips allowing users to useone device for a range of jobs. Complete kits come with a hot air blower for heat shrink tubing, soldering tip for repairs, high-temperatureBunsen tip to heat metal parts, and a heated knife that can cut, sealand shape plastics.

Additional Features

Since gas-powered soldering irons have become popular, manufacturers include more parts to allow customization. They include:

  • Snap-on lid to prevent the iron from damaging surfaces when it is not in use
  • Wet sponge that cleans the tip
  • Carrying case for storing all the soldering tools
  • Stand that keeps the hot tip off surfaces when it is not in use
  • Flame lock that allows you to keep the flame consistent without holding the trigger

The Best Gas-powered Soldering Iron: Power Probe Butane Soldering Kit

The gas-powered soldering iron enables you to work on a range of projects,including stained glasses and automobiles, thanks to its customizableheat output features. Despite being a gas-powered iron, it uses anexternal igniter that lights by a single press of a button. It delivers a temperature range of 950-2500 degrees Fahrenheit.
