Soldering gun buying guide

There are various types of solder guns on the market and deciding which one is appropriate for you might be tough. This guide will assist you in selecting the best solder gun for your requirements.

Solder gun wattage

When choosing a solder gun, it is essential to consider the wattage. The wattage indicates the power of the gun and determines how quickly it can heat up. Gun wattages may vary from 30 watts to 100 watts. Most guns fall in the 60-80 watt range. If you’re working on a project that requires a lot of power, you might want to go with a higher-wattage gun.

Temperature control

Some guns have a temperature control option, while others have a preset temperature. I do think that adjustable temperature is a feature you should look for – it makes it possible to control the temp based on the type of solder you’re using and the task you’re working on. Suppose you are working, for instance, with delicate materials, wires, or other electronic components. In that case, you will definitely want to choose a soldering gun with a temperature control knob so you can adjust the heat as needed.

Soldering gun tips

Because solder gun tips exist in a range of forms and sizes, it’s critical to pick the proper one for your purposes. The chisel and conical solder gun tips are the most widespread. The chisel tip is suitable for general purpose use, while the conical tip is better for precision work.

Further, it’s better to opt for a solder gun with a replaceable tip. Some devices may only take replacement tips from a specific manufacturer, making them more challenging to come by and ultimately costing you more money. So, do check whether the tip is easily replaceable before making a purchase!

Soldering gun vs iron

Many people think that a soldering gun and soldering iron are identical instruments, but they aren’t – each of these instruments serves its own purpose. The finest tool for you is determined by the project you’re working on. So, let’s find out the exact difference between a soldering iron and a soldering gun.

A soldering gun resembles a pistol and is designed for large-scale applications (e.g., home appliances, devices, radio circuits, etc.). It operates on a low voltage current, generates more heat, and warms up faster than a soldering iron.

On the other hand, a soldering iron is a weightless hand tool designed for light electric jobs and other delicate, precision projects. It’s more user-friendly and easier to control than a soldering gun.


What is the greatest advantage of using a soldering gun?

The greatest advantage of using a soldering gun is that it can provide a solid and secure connection between two pieces of metal. This is because the gun heats the metal to a much higher temperature than a regular soldering iron, which allows the metal to flow more easily and create a stronger bond. Additionally, soldering guns are much more versatile than regular soldering irons, as they can be used for various tasks such as welding and brazing.

Can I use a soldering gun for electronics?

Yes, you can use a soldering gun for electronics. However, it is important to note that soldering guns are not as precise as regular irons, so you may need to be more careful when working with delicate electronic components. Additionally, the high heat output of a soldering gun can damage some types of electronic components, so it is important to consult your product’s documentation before using a soldering gun.

What size soldering gun do I need?

The size of the soldering gun you need will depend on the task you intend to use it for. If you are working with large pieces of metal, then you will need a larger soldering gun that can output more heat. However, if you work with small electronic components, then a smaller soldering gun will be sufficient.

What are the types of soldering guns?

The two most common types of soldering guns are pistol-grip and trigger-operated. Pistol-grip soldering guns are designed to be held in one hand, while trigger-operated soldering guns require two hands. Both types of soldering guns can output a high amount of heat, so it is important to choose the type that is best suited for your needs.
