Buyers guide

What to look for when choosing a butane soldering iron

If a person first encounters such a device, then finding a suitable model may not be so easy. After all, you first need to decide on the type of work being carried out. Only after that, proceed to the selection of a specific model according to the following technical characteristics:

Maximum temperature value

This parameter affects the area of use of the device. Everything is simple here, the higher this value, the more work a person can carry out. However, if a product is purchased for domestic use, the recommended value is 1500° F. Professional devices designed for difficult types of work have a temperature of 2000° F.

The presence of a regulating element

Surprisingly, some companies release a product without this component, so they reduce the cost. However, it is best to buy products where the presence of a flame regulator is provided because it is more convenient to work with it.

Flame type used

There are several options – vortex, pencil, multipurpose. The first is designed for quick surface heating, the second is used for spot soldering, and the third is needed for people who do not need high temperatures. Therefore, everything here also depends on the requirements of the user himself.

Fuel tank capacity

The volume depends on how long the product can work without recharging.

What causes the ignition

There are two models with and without piezoelectric elements. It is preferable to buy the first option, as it is more convenient and practical.


How does a gas soldering iron work?

The principle of operation of a gas soldering iron is similar to that of a lighter. Liquefied gas is fed through a valve and ignited by an external element (piezo or external fire source). The main difference is the catalyst, which diffuses the flame. And only then the flame reaches the nozzle.

How to fill butane soldering irons?

In order for the device to function properly, it must be constantly refueled. For this, it is recommended to use refined butane, it is easy to find it since such fuel is used in all gas lighters.

Refueling should be carried out in accordance with the following steps:

  • The filling valve is tightly fixed;
  • The ignition button is locked;
  • The regulating element is placed in a neutral position;
  • Placing the soldering iron with the filling valve facing up;
  • Shake the gas bottle 3-4 times;
  • Installation of a filling tank in the corresponding part of the soldering iron;
  • Refueling.

There is nothing complicated in the refueling process, however, it is not recommended to neglect the established safety precautions, as this can be dangerous for a person, and it is important to remember that all work is carried out in a well-ventilated area. Also, access to the flame is excluded.

How long for a butane soldering iron to heat up?

In order for the soldering iron to perform its functions properly, it must be heated to a very high temperature. Depending on the model of the butane soldering iron and it’s features, the heating time of the tip to the operating temperature may vary. However, on average, it is 30 to 90 seconds.

Why butane soldering iron won’t light?

There are not so many problems with your butane soldering iron not starting up. The first reason may be the wear of the piezo element that ignites the gas. Catalyst burnout can be a second common problem. In this case, the soldering iron stops starting normally. Also, the problem may be in the absence of gas due to a malfunction of the valves.

How hot does a 100W soldering iron get?

A 100W soldering iron will typically reach a temperature of about 700°F (370°C).

How hot does a 50W soldering iron get?

A 50W soldering iron will typically reach a temperature of about 550°F (290°C). But, again, this is on the low side.

Can you solder with copper wire?

Yes, you can solder copper wire together. However, the key here is to apply a shiny coat of solder onto both surfaces that you want to connect. Once this happens, let the joint cool, and it will be as strong as the copper wire itself since they are now one piece.

Can you solder with aluminum wire?

Yes, you can solder aluminum wire together with a soldering iron. You need to heat it thoroughly and apply solder onto both surfaces that you want to connect.

How do I clean my soldering iron tip?

To clean a soldering iron tip, first, turn off the device and wait until cool. Then, take a damp sponge or cloth and use it to wipe the front of the tip. Next, use straight isopropyl alcohol or salt water to moisten the sponge/cloth and rub the solder residue off of the tip. Finally, you should dry the tip-off with a dry cloth before powering it back on.

How long does a butane soldering iron last?

In regular use, a butane soldering iron should last for about 100 hours of continuous operation. However, in time, the heating element will start deteriorating, and it will be less efficient or stop working altogether. When this happens, replace the element with a new one. The wick also needs to be replaced if dirty soot builds up and interferes with its ability to absorb alcohol.
