Using the Milwaukee 2488 - 20 M12 Soldering Iron is easy. First, make sure you've inserted a compatible M12 battery pack. Once you turn it on, wait for the green LED to light up, which means it has reached the operating temperature. You can then start your soldering job. When you're done, let it cool down until the red LED turns off, indicating it's safe to store. The 3 - stop pivoting head can be adjusted to fit different soldering situations. You can easily switch between the chisel and pointed tips without any tools. For maintenance, keep the soldering tips clean. After each use, wipe off any excess solder. Also, store the soldering iron in a dry place. Don't expose it to extreme temperatures or moisture. And always use it with the proper safety equipment, like safety glasses.
