I know; how does it feel when you try to solder an enameled wire when it doesn’t stick to it? It’s so frustrating that sometimes you think something is wrong with my tools. Fret not; in this blog post, we’ll learn how to solder enameled wire easily like a pro!
Before we start the process, here are some facts about the enameled wire that will cool down your frustration.
Why is Enameled wire so important?
This almost naked enameled wire is more efficient than a general thermoplastic or thermoset-coated wire. The thin layer of enameled wire allows us to make compact and efficient windings and coils, which save space. It also reduces electromagnetic interference and weight. It can withstand higher temperatures, chemical resistance, and mechanical stress. So, please don’t get frustrated; it has to be this way for several reasons. Now let’s come to our main question: how to work with enameled wire when soldering?
What you’ll need:
Before we jump into the how-to, let’s gather our supplies:
- Enameled Wire: Of course, you need the star of the show. Make sure it’s clean and stripped of any damaged enamel.
- Soldering Iron: Get a high-power soldering iron, something like 60 watts. The copper wire dissipates heat quickly, so a high temperature is recommended.
- Solder Wire: A good quality solder wire with a flux core. If you’re using general wire, make sure you have soldering flux.
- Soldering Stand: This will safely hold your soldering iron when not used.
- Heat Shrink Tubing: It’s optional, but heat shrink tubing adds extra insulation and protection to your connections.
- Helping Hands: These handy devices hold your wire in place while soldering – like your extra set of hands.
- Safety Gear: Safety first! Wear safety goggles and work in a well-ventilated area to avoid inhaling fumes.
How to solder an enameled wire?
- : Prepare Your Workstation
Set up your soldering station. Make sure you have good lighting and a clean workspace. Are safety goggles on? Check!
- Strip the Enamel
It’s a crucial step because that enamel coat on the wire doesn’t allow sticking the solder. You can use a sharp utility knife or a dedicated wire stripper to carefully scrape off the enamel coating from the ends of the wire you want to solder. Be gentle because you don’t want to damage the wire beneath.
- Apply Soldering Flux
You can apply additional soldering flux if you don’t have a flux core soldering wire. It increases the wetting ability of the solder, causing it to flow more uniformly.
- Tinning the Wire
Tinning involves applying a small amount of solder to the wire. It helps in better heat transfer and ensures a solid connection. Heat the wire and touch the solder to it. The solder should melt and evenly coat the wire.
- Soldering
Position the tinned enameled wire where you want the connection. Heat the wire with your soldering iron and touch the solder to it. Try to achieve a shiny and smooth solder joint, which indicates a healthy connection. Keep your hand steady and wait till the solder melts evenly on the surface.
- Insulate (Optional)
If you want extra protection, slip a piece of heat shrink tubing over the soldered area before soldering. Heat it carefully to shrink it and secure the connection.
- Clean Up
Remove any excess flux or debris with a brush when the joint cools down naturally. You can also use 99% isopropyl alcohol.
Pro Tips: If your solder isn’t shiny, apply more flux and increase the temperature if you’re using an adjustable iron. Also, make sure your Iron tip is clean.
General FAQs
Q1: Can I use sandpaper to strip the enamel?
A: Sandpaper is abrasive and can damage the wire. But, yes, it’s possible with the high grit sandpaper, something like 120 or higher, and be gentle. It’s best to use a dedicated wire stripper or a sharp utility knife.
Q2: Why won’t my solder stick to the wire?
A: It could be due to insufficient heat or dirty wire. Ensure you’re using flux and your soldering iron is at the right temperature.
Q3: Can I re-solder a connection if it doesn’t look good?
A: Absolutely! Just reheat the solder; remove the excess with a solder wick or a solder sucker when it’s molten. Now, you can redo the soldering.
Conclusion
There you have it – how to solder an enameled wire like a pro! Remember, practice and patience are key to mastering this skill. So, grab your soldering iron and follow our steps. Thanks for reading, and keep crafting!
