Might work.I am really interested in driving a generator or alternator and using just the output from them.

: : : Has anyone made or know of plans to make a portable welder from a generator or alternator? : : I have seen them built from old aircraft D.C. generators. : Saw pictures of one once that was built on a lawnmower deck. Had a 3.5 Briggs engine belted to a 12 volt alternator which charged a BIG 12 volt battery. Welding was done with battery power, and the alternator simply re-charged it. Might work for intermittent use. The system would need some means of controlling how much amperage was available at a given time, because a dead short across the battery would provide many times the desired amount. There would also be some safety considerations with such a device, including sparks getting near the gas tank, and the potential of battery explosions due to hydrogen gas accumulation during charging. I'm not saying it's a GOOD idea, just that I saw pictures of one!
