How to weld with dual batteries, jumper cables and a welding rod- video

[overlander]

For stick welding Al E4043, reverse polarity (electrode positive).
If you're thinking a Land Rover body panel E3003 might work better, but using batteries would probably be too hot for something that thin.

I can't think of a circumstance requiring a body panel to need to be welded to get out of the field and back home. For that, I would say carry a small piece of sheet aluminum, a hand drill, tin snips and a rivet gun with some aluminum rivets of various lengths.

"Getting back home" welding is chassis, SUSPENSION and power train!

Oh, I agree. I wasn't suggesting it, just answering the question.

Thanks, great vid!

Does anyone have any thoughts on
a) What this will do to your batteries? (I can't imagine a direct short is good for them)
and
b) How long you could weld like that without draining your starting battery?

Thanks,

It is not a direct short. You will get around 100 amps or so through the 1/8" rod, maybe a bit more, much less than a starter. Assuming 50 A-h batteries, you have half an hour, which is a huge amount of time.

That's some MacGyver stuff there very handy trick. Thanks for sharing sir.

Awesome. Now I gotta take some stick welding classes at the local trades college.

3 batteries work even better. We had to do it at TOTH. 2 didn't get enough penetration for us. 3 did. Good video!

Great idea, until you go to start your vehicle again and realize your radio settings are lost

Great video, makes me want a dual battery setup and this is one more reason to add to the list.
