This is a very dangerous way to do welding! The battery is seeing a short
circuit, and can explode. I have heard of some serious accidents doing this
practice. Tell your friend to get himself a proper welding supply that is
designed for this type of work, and is safe.

The battery will be making high internal heat between the plates, and
releasing hydrogen at the same time. This is a bid combination! The state of
this is very unstable, and not safe.

A friend claimed he was able to use a car battery as an arc welder. Is this
possible? Would it damage the battery?


Any responses are appreciated!
