    Here's an article on how they work:

    In my opinion, it wouldn't really be practical for someone to try to make a larger one at home.

    If you try to use solid copper wire and high current, you will most likely fry whatever components you're trying to solder.

    Weller makes, or used to make, soldering "guns" that used high AC current to heat a copper tip. These are not recommended for soldering electronic components, but I knew people who did. I personally would not use one for such purpose.
