Review on 🔧 Efficient Soldering with Tweezer Soldering ZD 409 Circuit Specialists by Jim Reinhardt

They don't heat up quickly and aren't easy to set up. They take too long to melt the solder, which can date the components, but they can be used. They also have Chinese clones that can be substituted. Make sure you flood them with solder before removing the components to reduce the lifespan of the components you are removing. If I had to buy them again I wouldn't spend money on them as I could use two soldering irons more efficiently.
