Specifications: The tip is made from copper and not electroplated, easy to tin and diamagnetic, suitable for lower temperature soldering. Don't leave your iron running for hours and hours if you are not using it. This can make the tip get black oxide cover. Try to tin the tip as it heats. If you leave it on too long or run it too hot it will burn off the solder and go black again. These soldering tips are suitable for soldering stations.
