    I wonder if they can get sued for publishing this?

    battery in series with altenator to increase voltage for welding,
    overdrive the field, I've heard of it being done.

    Probably works best old-school diesel engines where there's no
    electronics to fry.

    He goes in to that, advising removal of any built-in regulator. The
    schemo is simple enough, but addtional details are included, here:

    Also, he's trying to outfit his jeep with an on-board welder of
    similar design:

    The alternator can put out way over a hundred volts at 6 or 7 thousand
    rpm. As for the amperage, I've had my Ford 3G alternator put out over
    150 amperes, as measured with a dc clip on ammeter. Feeding that welding
    current backwards into a lead acid battery would probably cause an
    explosion.

    The battery has to be charged via another alternator, regulated at
    normal output voltage, or a battery charger.

    I notice with some amusement that one of AlwaysWrong's multiple
    identities has now chimed in...

    He's told me this three phase motor acting as a generator is safe:
