Anyone try welding with 2 car batteries?

The guy at the welding shop says one battery works - tried it can't keep an arc going.

Has anyone tried two?

Or 3?

In series of course.

I was trying to use it like a regular DC arc welder, not a carbon arc torch.

How long will it last - enough for a quick "trail fix?"

Thanks in advance, Rich.

Re: Anyone try welding with 2 car batteries?

Well, not first hand. But I've wathced Jeepgod weld with 2 batteries and jumpercables before when we didn't have an on board welder with us. He welded some spring perches on and they seemed to hold fine. I think it's an emergency only type of thing. (we did have welding rod)

Re: Anyone try welding with 2 car batteries?

Of course, just for emergency trail fixes.

I've used the alternator type welders on the trail a few times, and frankly I wasn't impressed! Wasn't impressed with the $1200 price tag either.

I was thinking if it will do a two or three inches without re-charging - there might be some underhood room available for a tractor battery - small, yet powerful. Then it could be set up to go in series with the regular battery for 24 volts.

If it takes 3 batteries there probably isn't enough underhood room for them.

Cables, welding rod, and a folding canvas hood would make it doable -- for cheap ---- if it works!

A trick I know works - done it a couple of times. 2 batteries in series, the carbon from the center of a regular flashlight battery sharpened to a point, and a coat hanger.
Strike and hold an arc with the carbon for the heat, feed the coat hanger or baling wire like welding with an oxy acet torch. Not pretty, but gets the job done. Again, it's just an emergency trail fix to get you home.

Thoughts? Experiences?

Pat used 2 batteries, welded up the perches on a D-20, both sides of axle, both sides of perch...4 times 3 inches maybe. Put one of the batteries back in Russ' Jeep and it started right up...

I have been thinking of getting one for my shop also as a primary welder and Ebay has them for the best prices.

Re: Anyone try welding with 2 car batteries?

if you want something for trail fixes.. two batteries... and some welding rod would get you buy... and you could weld for long enough to fix most anything on a trail...
i also have the ready welder that is a damn fine unit.. you weld about 45 minutes before you have to re-charge the batteries.. and it will weld up too 1/2" with 2 batteries.. its a hand held mig welder.. can use gas or flux core... it can also be hooked up to a standard mig welder.. and you can use it for aluminum... and you find them for under $400... i would tell you get one.. i love mine...

[img]images/graemlins/smile.gif[/img] Elusive.......I'm putting that "freeway fix" that you mentioned into my: "Best of the Grapes of Wrath" get-by-somehow list. That's right up there with making a transmission part for a 1922 Dodge with a file and a hacksaw alongside Route 66 in 1932; or putting bacon rind in the rod bearings to get it home.

Hey Rrich. Try this. It is a homemade job for onboard welding. No experience with it because it uses a ford slternator, but still thinknig bout it
