ok it did not explode and seemed to work very well in the revs range of 1300 -1800
i tried 2000 but it was too much for the 3/16 6011 rods i tried
at 900 idle it sparks but won't arc so it needs around 60 volts or so to weld nice
the altenator seemed to be fine with what i am doing no noises or exessive heat
so far so good ill have to test it more
