I got the machine back from the kid and looked at it for a while.
Nothing in earnest because I had to do some errands with SWMBO. While
we were out, I stopped in at a Miller authorized service center and was
able to speak to someone knowledgeable about the problem. I asked him
if he had free estimates and he said sure. You give us $108 and we will
give you a free estimate. Anyway, He asked me what the symptoms were
and when I told him he said that is sounded like what some of you are
probably thinking. Low voltage.

So I am wondering how that can be. I am using the dryer outlet in the
house and the dryer still works so that can't be the problem. I've used
it many times before. Used the same extension cord that I have used
many times in the past so that shouldn't be it. It's IS getting 240
volts damnit!!

So we get back and I start looking into it again. Sure enough it is
only getting 117.5 volts. WTF?!?!? SWMBO comes out and sez something
like " The last time you used it was at the kids house. Didn't you have
to switch the plugs over there?" Then the "AWWW SHEEEEEIT!" moment.
Sometimes I just hate that woman. :-) She has a way of doing that to
me. No I didn't remember that. I had to swap one of the ends of my
extension cord to match the outlet in his garage and then when I was
done I swapped mine back on again. Only I when I put mine back on I
inadvertently switched the white and green wires. SON_OF_A_BEEACH. I
fixed my cord and the welder works fine again.

Thanks for all your help anyway.

I don't think I offered any suggestions on your particular problem because
all my thoughts had already been mentioned by others but thank YOU for
letting us know how it worked out! It's frustrating when someone comes here
and ask for help with a problem and never lets us know what happens. :-/

And, it is always good to know that even when we think we checked ALL
the obvious stuff, we may have missed something REAL obvious!
