I've actually tried this to see how good it works. It's not real hot, but it does weld. I think 3 batteries would work good. I carry welding rods, a welding face shield, jumper cables, and an electrode holder/cable/battery clamp in my off-road Jeep for field repairs.

And here I went and needlessly blew all kinds of money on a mig welder last year....

Yep, sort of works but a real one works soooooo much better.
In fact so much better that they can be used in the shop.
