    OK Weldors, I just found the info I was looking for, I was wrong on the percentages, AC is 3 to 4 times more likely to kill as DC, here is a link to a good read...and I sure hope this helps someone.....Paul

    Quite a few years ago, in regard to the NYC subway where the third rail is about 400 VDC, I asked a professor of electrical engineering about the real dangers of getting electrocuted, hypothetically of course, over 400 VAC. He wasn't sure. He said perhaps the zero crossings of AC may give you a better chance of surviving, but he didn't know. And so, I never really knew. And if you do a search the answers are all over the place. So, finally, I have a good answer. So Paul, thank you very much!

    AZJoe, you are quite welcome, the other day I was doing some electrolytic rust removal, battery charger with negative lead connected to part and an anode with positive lead placed in bucket of water with baking soda. 12V 2 amp charge rate, well, I learned not to touch both at the same time......now me and Don King have something in common.......

    Default AC SMAW on an inverter power source question

    Lol. !! Story of my life, been doing this off & on for 35 years. Back to full time. And just burnt my hand for the millionth time tacking up a piece.
    I'm to old & stubborn now to learn any better.
    Thx for the laugh, glad to know I'm not alone.
    :-)

    Yep. Wear gloves, did the hole in the glove trick two weeks ago. Had it taped, ha ha know better, nice round red hot ball found it's way in and sat on my cuticle, needless to say with moves like a Ninja it wasn't quick enough, left a black crater!!
    This time I even had my trusty Miller gloves on & blistered my thumb through the glove. Hay maybe I should ck the Limited Warranty on gloves wonder if it's covered. ?? Maybe not, like ma ma always said. Ya just can't fix stupid. Good thing the Lord created us to heal or I'd been gone long time ago.
    Take care Greg
