How Long Does It Take For A Soldering Iron To Cool Down

Always remember that there are no “silly” mistakes when it comes to using electric tools. 

I learned it the hard way when I accidentally touched the tip of my hot soldering iron. Thank God I was wearing my thick gloves, or it could have become a graver problem. But, it did leave a mark on my gloves as a lesson of patience. 

When I went to my husband to tell him about this crazy incident, I was shocked to know that he has had similar experiences in the past. And to my surprise, he said that many people don't even know that working with a soldering iron requires a proper wait time. 

Hence, I took it upon myself to research the best way to work with soldering irons and find ways to avoid making common mistakes. This has changed my perspective on working with this tool, so I thought of coming up with this informative guide. 

Hi! I’m Stacy Smith, and today I will tell you everything about how long does it take for a soldering iron to cool down. Without further ado, let's begin!

How Long Does It Take For A Soldering Iron To Cool Down

What’s The Right Wait Time?

I know that it should be an easy question to answer, but I found out that it isn't. Most people tell you that waiting for 2-3 minutes is fine before you move on to changing the tip. 

This waiting duration works for the commonly used soldering pencil, but it might not work for a bigger soldering gun. Hence, here are some points that may affect the cooling time of a soldering iron: 

1. Type Of Soldering Iron

I'll admit I was surprised to know that there are different types of soldering irons. The most common one is the electric soldering pencil that's found in most workshops. Another popular variant is the electric soldering gun that works well for larger projects. I also found that there is a variant of butane ignited soldering pencils. 

Reading a manual may not be an exciting task, but it will give you key information about using the particular soldering iron, including its right wait time. Moreover, the temperature range can also differ among various models of soldering irons, so it's always a good idea to know enough about your power tool. 

2. Temperature

While using a soldering gun, you may need to change the temperature depending on the materials you are soldering together. However, some people like to hike up the temperatures of their soldering irons way beyond the recommended level. 

You would be wrong to think that it's a great idea, as the situation can quickly become a fire hazard. Apart from that, the high temperature can also ruin the integrity of the metal and make it less durable. 

And, the most obvious fact is that if you run the iron at a high temperature, it would take a longer time to cool off. Keeping the temperature at a lower range also helps to prolong the lifespan of a soldering iron. 

3. The Iron Tip

The tip of a soldering iron gets very hot, and that's why the wait time is required to let it cool before you can handle it. These tips come in different sizes, and those that are on the thicker side take a longer time to cool. 

It's also quite important to handle a tip carefully as it may contain remnants of lead and other metals. So, be sure to read the manual provided with the device to get a better idea of handling the tips. 

I also came to know that many people deviate from using the tips recommended by a brand. Please don't make this mistake as it can harm the tool, and it also makes guessing the cooling time more difficult.

Can You Cool Down A Soldering Iron By Dipping It In Water?

Even though it seems like a great idea to dip your soldering pencil in water, it can actually ruin the whole tool. Metals tend to expand and contract based on temperature. Hence, when you soak the tip in water, the metal will contract suddenly, leading to the formation of cracks on its top layer. 

This damage to the tip can reduce its lifespan as well as its ability to solder materials. Water can also seep into the electrical parts of the tool. So, don't even think about dunking your soldering pencil in the water.

How To Change Hot Soldering Iron Tips?

Even though I don't really work on projects where there's a constant need for changing tips, I found that many people want to know about the process of changing the hot tips. Ideally, a person should be working with multiple soldering irons to maintain safety, but that's not possible for everyone. Moreover, someone like a DIY enthusiast cannot be bothered by buying multiple pieces of the same tool. 

With a little more hunting on the internet, I came across two solutions for changing the hot tips, one with the help of pliers and another using heat-resistant gloves. While working with the pliers, make sure not to apply too much pressure on the tip. You should also place the new tip with the pliers as the rest of the tool will still be hot. 

And, while using the heat-resistant gloves, try to get a pair that can resist a temperature that's a hundred degrees more than the heat produced by the iron you’re using.
