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 ??

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 ??

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 --
then I AM PROUD TO BE PLONKED !!

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 !!)

Yes, I was surprised. I was talking about fly by wire and you said it was
all done by hydraulics so I took a guess at what you thought you thought
and I get to be the idiot because you are stupid.
In the meantime you snipped all that stuff you wrote about jodhpurs, warm
dubbin and the mother of the girl next door.


PLONK!

"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?


Bye.
