Video DIY welding using car batteries!

[VikingAdventurer]

I randomly came across this video today, and I figured that it might be quite useful to those of us who are of the rubbertramping/homesteading inclination.

By far the most useful vid I have seen on this site! Wicked awsome man! Thanks!

Are those lead acid or gel cel? Nice.

The video didn't specify. I would just get the cheapest ones, test it, and if it didn't work right I'd go get the other ones.

holy shit man..
i haven't even *watched* this fucking video, but the concept itself already rates as close to a tie with # 1 as i can think..

i carry a spare marine & typically a spare auto.. my marine had an issue with ground fault, & melted part of the terminal.. only lead, but still holds a charge..

this fucker gets archived!! thanks!!

even if it is just *tack* welding.. fkng great!!

makes me wonder..
could you get a high voltage coil & do any low amp work at, say, 10Kv?

 

[creature]

this would probably be good for waterpump housings, possible radiator repairs, transmission lines, & maybe some mounting applications..

i doubt the technique would service high stress/large area requirements (struts, hinges, cracked blocks, etc.), but man..
i am going to look at this stuff in depth..

Thanks again!!

Great find, O One of Ancient Horns...

So it tried this, and its ok for some stuff, the batteries I found were pretty shitty but it can be useful in a pinch. Idk how much I would trust these welds but if you break a spring mount or something of the like I think this would get you back to a real welder for a proper repair. Thanks.

remarkable to know that one can simply metamorphose their solar/steam/wind/etc -powered battery bank into a welding apparatus in an 'off-grid' living situation. And heck, the welds in the video look cleaner than the ones generally produced by my 120V flux-core welder.
Utilizing this can help one build a 'bike generator' to recharge said batteries and on and on . . . ( my attempt at sharing the web link to that article/video was futile since this is my first post and it was considered spam to enclose a link, but for any interested, google search : "when disaster strikes bike generator will give me power". Interesting fella)
such a useful find after a day of metal working - cheers

I was fucking around in the woods near Saint Johnsberry vt and came across a compound that had a battery bank powered welder. The compound was constructed out if giant heating oil tanks dug into hills or free standing with doors cut in them. I spent some time admiring their junk creations and battery welder, then booked before the owners showed up.
