    There has been some mention of using an arc welder to power a krypton arc
    lamp rated at 8000w (200v/40a.. make it 50a for a little headroom)

    I was under the impression that arc welders operated well under 200v output,
    and was wondering if someone could explain either A> how an arc welder works
    such that i could produce the output I need, or b> what modifications might
    be neccessay to get the desired output ??
  2. Yes, typically around 30 - 90 volts IIRC. You CAN get a shock off them if
    you are wet and grounded.

    we knew this already -- I do plenty enough with my 120v arc welder on my
    trailer mounted antenna tower -- do you have something to contribute that is
    more in line with the question ??

  7. Yeah. They have to be extremely stupid for that but this dumbfuck achieved
    that level of failure.

    Hang on.

    You plonked me earlier over your inability to deal with fly by wire.

    If wanting a responsive answer is all it takes to get plonked around here --

    Its not MY fault that you dont know enough about arc welder internals to
    answer my question !! (or if you do, that you choose to give me shit rather
    than answer my question !!)

    Go ask your question in 'sci.engr.joining.welding'
  11. You seem to be confused.

  13. "Fly by wire" is done with hydraulics. Have you not noticed what happens
    when all of the hydraulic fluid in a plane's control system is lost?

    mee too.
    It's basically a big transformer.
    connect the outputs of two (or three?) in series?
