What do you get when you combine an arc cigarette lighter and some scrap glass and metal? [NightHawkInLight] created a simple plasma cutter project along with some hot glue and a few simple tools.
If you aren’t a smoker, an arc lighter uses a high voltage spark to light the cigarette. He essentially cannibalizes it for use as a power supply. Any similar high-voltage power supply should work just as well. He also uses the same cigarette lighter power supply for an arc pen, that we covered earlier.
The cutter uses a small steel screw and a bit of glass with a handle as the cutting head. A metal base serves as the other electrode and a heat sink. For the plasma pen, two brass electrodes form the spark gap and a brass tube blows air to direct the arc to the work piece. If you are looking for something bigger, you could lay out about $8,000. Or–not really a plasma cutter–but you could go the very cheap route, instead.
