SOLDERING IRON USING GLOW PLUG

[mariost]

A useful tool we can use in a place where there isn' t electric current. For example in the car , at the country etc. It needs a 12 volt battery. It works with about 20 A current , so I 've put a 30 A relay that gets the order from a small switch. The power of the glow plug is about 230 to 250 W so we must not operate continuously more than 8-10 sec to avoid overheating. I ' ve also connected a piece of copper (or bronze) to the end of the plug to have better adhesion with the soldering wire.
