How To Use Butane Soldering Iron

A butane soldering iron is one of the most flexible and user-friendly items you can add to your workshop. These remarkable pen-shaped devices may be packed in a backpack for on-the-go repairs and fit in the palm of your hand.

They can form extremely strong connections between electrical wires and other materials. A butane soldering iron is a multi-purpose tool that can cut wires, bind materials, and solder.

Being portable, you may think they lack compared to corded soldering irons; however, these devices can match any soldering purpose you may have. However, they do work differently from an electric soldering iron. In our guide, you can find how to pick a butane soldering tool and basic butane pencil torch instructions.

Uses of Butane Soldering Iron

By the end, you’ll be able to pick the right portable soldering iron and know how to use a butane soldering iron for jewelry making or fixing a broken circuit board. (Read Guide to Cleaning Battery Terminals Without Disconnecting)

How Butane Soldering Iron Works?

The hot knife tip of the soldering iron reaches temperatures of around 800 F.

Some portable soldering irons allow you to change the temperature to meet your needs. As the name implies, the butane iron uses butane to reach high temperatures.

It heats things like pads, PCBs, metal, and wires and quickly melts the solder. The solder is then applied, and the butane iron is used to join the two pieces.

When choosing a soldering iron, there are a few things to consider.

  • Wattage
  • Temperature Control
  • Size and shape of the soldering iron tips


The wattage of a butane soldering iron is an essential factor to consider. Most soldering irons used for electronic repairs have wattages ranging from 20 to 60 with 50 watts of power, being sufficient for soldering circuit boards or modest electrical projects.

If your soldering iron has a higher wattage, you’ll be able to finish more jobs with it. In addition, the higher the wattage of the soldering iron, the longer the soldering tip can keep heat, allowing the solder to produce a smooth and solid bond.

Temperature Control

Temperature control is critical for any soldering iron since it can damage an entire soldering process if it is not done correctly. Devices should be ESD Safe, so you know you have some protection.

With this control, the iron reaches a sufficient temperature to complete a task, and the temperature is maintained for the period of use. In addition, you’ll need an iron that offers a longer runtime.

A short runtime means the device can take an age to get up to temperature, and once it’s hot, the built quality may not be high enough to prevent you from burning your fingers.

Tip Size and Shape

A butane soldering iron should be adaptable enough to be used in various situations. As a result, you’ll need to use interchangeable and removable soldering tips for such devices. In addition, it is recommended that you use tips from the same manufacturer so that compatibility concerns are avoided. (Read Coolant Reservoir Empty But Radiator Full – What To Do)

Other factors can include:

Length of Duration: Runtimes vary from 10 minutes to 2 hours. You need one that lasts long enough to complete your tasks. One-hour runtime on a full tank should cover most soldering jobs you can carry out.

Size: You need an iron that fits in the hand, too large, and it can be cumbersome, and too small means it may have a small butane gas tank.

Body: The body needs to be durable and offer safety. It will be holding a small pressurized tank and red hot soldering tips, both of which can cause harm.

A Stand: A stand can be vital as you need somewhere to put the hot iron.
Cordless: Using butane as the heating fuel means your device will be cordless. It is this that makes them an effective portable soldering iron.

Brand: You can find many imported models of butane irons that offer a low price. However, you can get branded items that offer more in every department with just a small extra cost.

Safety: Pick a butane soldering iron that is EDS-Safe

How a Butane Soldering Iron Works?

Here, you can see how to light a butane soldering iron and a few other tips on their use.

Lighting Your Butane Soldering Iron

Lighting Butane soldering iron

The instructions below a generic as some models can differ in operation.

  • You will find an on and off switch.
  • Besides this, there may be a lever to control fuel flow and gas supply and thus to raise or lower the tip temperature.
  • You could also have a lever for the ignition of your butane iron.

Fueling Butane Soldering Iron

To begin, you’ll have to fuel your soldering iron. Butane fuel is available for purchase at the hardware store.

  • Fill the canister with fuel by pouring it into the refill port at the bottom. To use the refill tip, upend the gasoline canister into the cavity and squeeze. When some fuel bubbles to the top, you’ll know it’s full.
  • It’s vital to prevent overfilling the soldering iron. You’ll make it spit open flame everywhere, which could be hazardous.
  • When you’ve finished fueling, don’t ignite your iron right away. You must wait for the gas to stabilize before using it.

Lighting Your Soldering Iron

  1. From the off position, turn the regulator on. You will select levels based on the amount of heat you desire.
  2. To light your soldering iron, use the igniting lever. To prevent accidental ignition, certain irons incorporate safety locks. Remember to release the safety lock while holding down the ignition button.
  3. When the soldering iron is in the middle position, you can light it. Remember that butane soldering irons heat up fast and should be hot enough to solder in approximately 20 seconds.
  4. Use the adjustable temperature function for the task you are doing
  5. Return the heating lever to the down position to turn it off.
  6. If you want to remove the tip before storing it, wait at least 2 minutes until it is cool before touching the hot tip.
  7. When not in use, keep your soldering tool on the stand.

Other Uses For a Butane Soldering Tool

Use Butane Soldering Iron as Hot Blower

Your butane soldering iron can also be used as a hot blower. To ignite and operate your hot blower, disconnect the soldering tip and follow the methods we’ve detailed above.

Use Butane Soldering Iron as Pencil Torch

Butane soldering irons are versatile, and some models can double up as an emergency torch. Position the metal sleeve instead of the soldering tip, and the torch will be lit using igniting procedures above. (Learn How To Change Dremel Bit)
