Welding with a battery

Is there a book out there to tell you how to weld using a battery?

Trying to weld with a car battery, unless you're experienced, sounds like it poses an opportunity for a hydrogen explosion and sulfuric acid sprayed all over the place. But I have heard of it being done in a pinch. Good luck.

Hi , I found this article about welding using 2 or 3 car batteries to weld with excellent results, paste the next link on your browser's address box and press 'enter':

That's it, hope it helps a lot of people.

Sorry my question was not very clear. The Idea is to know if you can weld any part of a car with electric arc without disconnecting the battery.
