The 70's wrote: I've heard somewhere (here?) that it's possible to weld with car batteries(clip) ^^^^^^^^^^^^ When I was shopping for a small wirefeed welder, recently, one of the units I was shown was a small welder in a plastic carrying case, designed to run off a car battery. I understand they are popular with the off-road crowd, and I can see why. ^^^^^^^^^^^^^^
true, and if it is, how would one go about it?(clip) Just connect all the negative poles in series, then the positive? ^^^^^^^^^^^ If you want to hook the batteries in series to get 24 (or 36) volts, you hook positive to negative to positive to negative (and so on). Hooking all the neg's together and all the positives will still give you only 12 volts, but with one or two thousand amps capacity, which you don't need. The welder I saw ran off a single car battery. ^^^^^^^^^^^ (clip) making my own welding rod (info from one of the previous posts, wrap a coat hanger in wet newspaper ^^^^^^^^^^^ Is this true? I'd definitely like to know more!
