Key features

Power Source - Consider the power source of the soldering iron. Is it powered by electricity via a wall plug, by batteries, or butane?
Tip Size and Shape - The size and shape of the tip will depend on the application and the materials being soldered. Consider what size and shape of tip you need for your project.
Heat Setting - Soldering irons can be adjusted to have different heat levels needed for various projects. Look for a soldering iron that offers an adjustable heat setting.
Safety Features - Safety features are an important consideration when choosing a soldering iron. Look for soldering irons that feature a handle cover, auto shut-off, and a secure base for storage.
Durability - Good soldering irons are designed to last. Look for features like a robust metal body and ceramic heating element that will provide a long service life.
Price - Price will be a major factor when choosing a soldering iron. Consider your budget and look for a model that offers the best features for the price.

Important considerations

Pros

Portability: Soldering irons are lightweight and easy to transport, making them ideal for hobbyists and professionals who need to complete projects on the go.
Versatility: Soldering irons can be used for different types of projects, from simple electronics work to complex precision engineering.
Safety: Soldering irons are designed to be used safely and can prevent accidental burns and fires when used properly.
Cost-effectiveness: Soldering irons are relatively inexpensive and can be used multiple times, making them a cost-effective choice for most projects.
Durability: Soldering irons are typically made of high-quality materials that can withstand wear and tear over time.

Cons

Cost: Soldering irons can range in price from inexpensive to very expensive, so it's important to consider what features you need and compare prices before buying.
Space: Soldering irons require a dedicated space on a workbench or table, and a power outlet nearby to use them.
Safety: Soldering irons can be very hot and can cause burns if they are used improperly.
Maintenance: Soldering irons need to be regularly cleaned and maintained to keep them in good working order.
Inaccurate Temperature Regulation: Some soldering irons have temperature control issues, resulting in an inaccurate and inconsistent temperature.

Best alternatives

Heat Gun - A tool with much higher temperatures than a soldering iron, allowing for faster and more efficient soldering.
Soldering Gun - A tool with a trigger and a heating element which can be held like a gun, producing high power for more intense soldering.
Soldering Station - A larger tool with a temperature control and interchangeable tips, providing more advanced features than a basic soldering iron.
Soldering Paste - A type of heating material in the form of paste which can heat up quickly and hold longer than wire solder.
Flux Pen - A pen-shaped tool that applies a flux material to a surface, helping to create a better bond.

Related tools, supplies, and accessories

Tip - A soldering tip is the metal part of the iron that gets hot and melts the solder.
Soldering Iron - A soldering iron is a tool used for soldering two pieces of metal together.
Soldering Wire - Soldering wire is a metal alloy which is melted onto the two pieces of metal to join them.
Flux - Flux is a cleaning agent which is applied to the surface of the metal prior to soldering to remove any contaminants.
Solder Sucker - A solder sucker is a small tool used to remove excess solder.
Heat Sink - A heat sink is a device which absorbs heat from the soldering iron to prevent overheating.
Soldering Stand - A soldering stand is a metal holder for the soldering iron. It allows you to safely set the iron down while you work.

Common questions

What is the difference between a soldering iron and a soldering gun? A soldering iron is a tool with a metal tip that heats up and is used to melt solder. A soldering gun is a tool which is powered by electricity, and uses a transformer to heat up a larger tip that is used to melt solder.
What type of soldering iron should I buy? The type of soldering iron you buy will depend on the type of project that you are working on. If you are working on an electronics project, you may want to purchase a soldering iron with adjustable temperature settings, as this will allow you to adjust the temperature for different types of solder. If you are working with metal or jewelry, you may want to purchase a soldering iron with a solid tip, as this will be better for providing even heat across the surface of the project.
What should I look for when buying a soldering iron? When buying a soldering iron, you should look for a high-quality tool that is designed to last. Look for features like adjustable temperature settings, an ergonomic design, and a comfortable grip. In addition, it is important to make sure the soldering iron is compatible with the type of solder you will be using.
How do I maintain my soldering iron? It is important to maintain your soldering iron by regularly cleaning the tip and making sure it is properly stored when not in use. To clean the tip, you should use a damp sponge and a soldering iron tip cleaner. It is also important to unplug the soldering iron when not in use, and store it in a dry, dust-free environment.

Trivia

An interesting fact about soldering irons is that they are very old technology, dating back to the 17th century. The first soldering irons were made of a thin metal rod that was heated in a burning coal bed. It was not until the 1940s that electric soldering irons were invented. This was thanks to radio technology, which enabled technicians to solder electronic components with the convenience of an electric soldering iron. Source
