bloz up,
Thanks for the response, that does make sense with the DC output. What really interests me though is if I'm using a generator that is spec'd at 20A max, what will my limitation be? Will I be limited to duty cycle, or amperage? I'm assuming amperage, but I'd love to hear from someone with a better understanding of the fundamental concepts than I have. I'm also interested in a guestimation of what 20A draw through the lincoln tig would max out at. Is it as simple as half? Ie, will it limit me to ~115A of the 230A claimed range? Also, what does that translate to in real world terms as in thickness of Al and steel?
Thanks,
Dave
