In this article, we’ll discuss some tips for troubleshooting when your solder won’t melt, and we’ll provide some solutions to get your projects moving again!
Reasons Why Your Soldering Iron is Not Melting Solder
There are several potential causes for your solder not melting when using a soldering iron. Some of these include:
- Your iron is not hot enough – The temperature of the iron needs to reach at least 400°F (204°C) in order to effectively melt solder. Make sure you’re using an appropriate iron and that it’s plugged in correctly.
- You’re using the wrong type of solder – Some solders require higher temperatures to melt than others, so make sure you’re using the right type for your application.
- The tip of your iron is oxidised or dirty – Over time, the tip of your iron can become oxidised or dirty, which prevents it from heating properly. Make sure you regularly clean and re-tin your iron’s tip to avoid this issue.
- You’re using too much solder – When too much solder is added to a joint, it can prevent the solder from melting properly. You should limit the amount of solder added to any joint for best results. [1]
Heating Element is Broken
If your soldering iron’s heating element has gone bad, it won’t be able to get hot enough to melt solder. This is an issue that can only be addressed by replacing the heating element or the entire soldering iron.
Not Plugged in Outlet Properly
Another common issue is that the soldering iron isn’t properly plugged into the outlet. Make sure you’re using the correct power cord and that it’s securely plugged in to avoid this issue.
Not Enough Time to Heat Up
If you’re not giving the iron enough time to heat up before attempting to use it, it won’t be hot enough to melt solder. Make sure you give your iron at least a few minutes to heat up before using it.
Wrong Solder
Sometimes, the solder you’re using isn’t appropriate for your application. Some solders require higher temperatures to melt than others, so make sure you’re using the right type for the job at hand.
Cheap Soldering Iron
Using a cheap, low-quality soldering iron can lead to difficulties with melting solder. Make sure you invest in a good quality soldering iron that is reliable and durable.
Oxidation
The tip of your soldering iron can become oxidised or dirty over time, which prevents it from heating properly. Make sure you regularly clean and re-tin the tip to avoid this issue.
How to Fix a Soldering Iron That is not Melting Solder?
Once you have identified the cause of your solder melting issues, here are some solutions that may help:
- Clean and re-tin the tip of your soldering iron – This will ensure that it’s able to heat up properly.
- Make sure your soldering iron is plugged in correctly – If the cord is not properly plugged in, it won’t be able to get hot enough to melt solder.
- Use the correct type of solder – Make sure you’re using the right type of solder for your application.
- Invest in a good quality soldering iron – Low-quality irons often don’t get hot enough to melt solder properly.
- Give your iron adequate time to heat up – Make sure you give your soldering iron at least a few minutes to heat up before attempting to use it.
Following these tips and solutions should help you get your projects moving again when your solder won’t melt. If the issue persists, it may be time to invest in a new soldering iron or heating element.
