how to use a soldering gun

Using the best soldering gun is much easier, safer, and comfortable than using a pen-type soldering iron. It has a gun shape design and a pistol grip that gives me an ergonomic feeling and provides less fatigue when holding it. Furthermore, some of the soldering guns have a solder feeder, making it a one-hand feature.

A soldering gun has a max temperature that is much higher than a soldering iron. Aside from this advantage, there are many more differences. I'll discuss these more in-depth below as I review and compare the soldering guns I've used before or are currently using.

However, consider these three main things to help you find the best-fit solder gun for electronics work.

Temperature settings: Not all soldering guns have an adjustable temperature So if this is crucial for my work, I'll look for this feature. After all, not all high-temperature soldering guns are suitable for all kinds of work. Sometimes, the maximum temperature of a soldering gun can damage electronic components, so they're only ideal for soldering cables and wires.
Power Output Control Features: Aside from the adjustable temperature range, the power control feature is also essential for most users. This feature allows me to control the watt output of your device, giving me better temperature control. It also puts the soldering gun into a low-temperature setting while on standby mode, thus saving power. Also, some units have two trigger positions that set the soldering gun in low power for the first click and max power for the second click.
Availability of Tips: A replaceable iron tip is one of the essential features that I look for in most soldering guns. That's why I prefer soldering guns with an easily replaceable tip. Some models only accept replacement tips from a specific brand, making it harder to find and end up costing you more.

In contrast, other soldering guns use the same tip type, allowing me to use any brand for my soldering gun.

What to Look for When Buying Soldering Guns

solder-gun-for-electronics

One of my primary considerations when buying a soldering gun is the brand. There are a couple of tool manufacturers whose products I trust. However, they tend to be more expensive than other options, so if I have to stick to a budget, here are a few factors to consider when buying a soldering gun.

Temperature Setting

You should always consider the temperature required for your jobs. After all, not all soldering guns can be used for light work that only requires low-temperature settings. Furthermore, other soldering tin, like lead-free solder, requires a higher temperature to apply.

For this reason, I recommend using a soldering gun or iron with less than 50 watts capacity if you primarily work on small and delicate projects. On the other hand, you can use a high-temperature heat gun with 60 watts of power and above for those large applications like wire soldering. Also, some workers prefer soldering tools with adjustable temperature control.

Power Output Control Features

If you need high temperatures for your work, then it's better if you get a soldering gun with power control settings. That way, you can pick the right amount of heat output for your application. Furthermore, it will also help you save electricity as it would typically switch to a low-power standby mode when not in use.

Availability of Tips

Most soldering guns in the market have interchangeable tips for using other tips to ease your work. That's why you should also consider easy iron tip replacement for your tools. If your soldering gun requires a specific tip that you only buy from one manufacturer, then you might have trouble finding a replacement for it in the future.

Solder Feed Feature

Nowadays, you can find soldering guns with an automatic solder feed controlled by the trigger. If you're working on soldering projects where you need both hands to hold the wire you're working on and the soldering gun, then you would find this feature absolutely useful.

However, not all soldering guns with a solder feed can accept all solder sizes. You should determine the solder diameter the automatic soldering gun takes before choosing. For best results, most automatic soldering guns work well with a 1mm diameter solder.

Included Items

Most of the soldering kit includes complete accessories that let you start soldering straight out of the box. However, not all manufacturers include extra tools like a desoldering pump and flux brush. So if you want to have a complete soldering kit, choose the model that provides all the additional tools you need.

On/Off Feature

Another great way to save electricity is by having an On/Off switch on the soldering gun. That's why I consider the On/Off button crucial when looking for an excellent soldering gun. You can use its On/Off feature to save power and cool the soldering tool without unplugging it.

Cord Length

I consider the cord length important, especially when using the soldering gun outside soldering stations. If the length is too short, I might have trouble using and maneuvering the tool. Although I can use an extension cord to lengthen it, it is still an additional hassle for me.

Price

Always remember that not all pricey products have excellent quality and features. Some low price soldering guns provide high-quality performance on a budget. So even if you can't spend too much on a good tool, you're sure to find a soldering gun that will last while still sticking to your spending goal.
