4 Different Types of Soldering Irons & Their Uses (2023)
Soldering is the technique that has been used in the world of electrical and electronic engineering to join two or more metals to create an electrical connection.
The soldering iron is used to heat the solder of the filler material, allowing the joining or repairing of components.
With the advancement of electronics industries, we have come across various types of soldering iron for a variety of applications. There are different soldering iron with different specifications and applications.
The standard soldering iron, temperature-controlled soldering iron, butane-powered soldering iron, cordless soldering iron, soldering stations, and hot air soldering stations these all are different types of soldering iron. These can be used for various soldering purposes.
In this article, we will delve into the world of soldering irons, exploring their various types and understanding their unique features and applications.
Let’s get started.
Different types of soldering iron
Now let’s discuss several types of soldering irons that are used for soldering purposes.
1. Standard soldering iron
A standard soldering iron is most commonly used by students, and hobbyists to create reliable electrical connections and repair components.
It consists of a heated metal tip attached to a handle and a power cord. The tip is made of a material with high thermal conductivity, usually copper or iron, and is designed to heat up quickly and maintain a stable temperature.
It is also called standalone iron or pencil iron.
To create strong joints, the iron is held like a pen, heated to the tip, and bought into contact with the joint to be soldered.
The heat from the iron transfers to the joint, melting the solder placed on it. As the solder melts, it flows and creates a strong bond between the components.
Applications:
- It is mostly used for electronics repairing and assembling work. They are essential to connecting components on printed circuit boards (PCB).
- Soldering irons are commonly used in educational settings, such as schools, colleges, and technical training centers. They play a crucial role in teaching electronics, electrical engineering, and other related subjects.
- For people who love to make new things, a soldering iron can be essential for them. They can create different craft pieces.
- It is also used in making beautiful jewelry by joining two or more metals.
2. Temperature-controlled soldering iron
The temperature-controlled soldering iron is a tool that is also used in electronics and in other soldering applications.
The main advantage that makes the temperature-controlled soldering iron superior to any other soldering iron is its temperature control feature.
This feature is very important especially when working with soldering wires and circuit components that require different temperatures. The higher temperature may damage them.
It consists of a handle with a heating element and a replaceable soldering tip. The tip temperature can be adjusted according to your need.
You can identify a temperature controlled iron easily. It has nobe or screen, as you can see in the above iron (Amazon link), through which we control the temperature.
Application:
- For delicate and tiny components which required precise temperature control during soldering, temperature-controlled soldering is the best choice. It allowed us to set the temperature according to our needs.
- Lead-free solder is used in soldering as it has a high melting point so the use of temperature-controlled soldering iron makes it easy to set the desired temperature.
- Some materials used in electronics or other industries are sensitive to high temperatures. Temperature-controlled soldering irons allow the user to set lower temperatures, ensuring that the material remains unaffected while still achieving proper soldering.
- It is also useful in performing rework or repairs on existing soldering joints.
Overall, a temperature control soldering iron is a versatile tool that provides precise temperature regulation, ensuring optimal soldering conditions for a wide range of applications.
3. Butane-powered soldering iron
Butane gas is used to power the butane-powered soldering iron as its fuel source.
Unlike traditional soldering irons that require an electrical power source, butane-powered soldering irons are portable and don’t need to be connected to a power outlet.
Where access to electrical outlets is limited or unavailable the use of butane-powered soldering iron can ease the situation.
The butane gas is stored in a refillable reservoir within the soldering iron. When ignited, the gas is converted into a flame that heats up the soldering tip.
The heat from the flame allows the soldering iron to melt the solder and make electrical connections.
Applications:
- Butane soldering irons are ideal for repairs and soldering tasks in outdoor settings where access to electricity may be limited or unavailable.
- A butane-powered soldering iron is handy to help in repairing automotive and marine industries
- In emergency situations where electrical power is down or unavailable, a butane-powered soldering iron can be a valuable tool. It enables you to perform critical repairs on electrical systems, and communication devices.
- Field technicians, engineers, and researchers often require a portable soldering solution for on-site repairs or modifications. A butane-powered soldering iron can be useful.
It is significant to note that butane-powered soldering irons need their butane gas reservoirs to be periodically refilled. The duration of refiling depends upon the specific model.
4. Cordless soldering iron
As the name suggests the cordless soldering iron that operates without any power cord or external power source. Instead, it is powered by batteries or butane gas to provide portability and convenience.
The absence of a power cord eliminates the need for an electrical outlet, making the cordless soldering iron suitable for use in remote locations, outdoor settings, or situations where access to electricity is limited.
The heating element of the cordless soldering iron quickly heats to the appropriate temperature for soldering. The soldering iron can melt solder, which is used to join or repair electronic components, wires, and other materials.
Applications:
- For the technician working in the field, cordless soldering is a valuable tool for them. They can perform on-site repairs, modifications, or soldering tasks in remote locations where access to electricity is limited or unavailable.
- Cordless soldering irons are popular among remote control (RC) hobbyists who need to solder or repair components in their RC models. They provide the freedom to work on RC cars, drones, planes, or boats without the hassle of cords or limited mobility.
- It is also helpful while working on DIY projects and doing craft work.
Cordless soldering irons are available in different models and power sources. Battery-powered soldering irons are typically rechargeable, allowing for extended use before needing to recharge.
Conclusion
The soldering iron has different types according to the applications and project requirements. You have to choose the soldering iron that best suit for your situation.
The standard soldering iron, temperature-controlled soldering iron, butane-powered soldering iron, and cordless soldering iron. All these are the types of soldering iron with specific applications.
For the school project or doing some craft work the standard soldering iron works perfectly. If you are working with delicate components, and want a precise temperature then a temperature-controlled soldering iron will help you to solder heat-sensitive components on PCB.
On the other hand, the butane-powered soldering iron and cordless soldering iron are portable and provide reliable connections even when the electrical connection is not accessible.
