you are prob right, it may have been cast steel. i wasn't advocating using 6011 on cast iron, it was all i had at the time. i just meant sometimes things can work that aren't meant to so if you want to try something unorthadox like the mig, go ahead. i wasn't sayin i'd do it. i also welded a slant 6 block that had a cracked water jacket that held as well 15 years ago. i drilled holes at the end of the crack and preheated. i wish i could have buried it in the sand but i just kept applying less heat for a period of time with the rosebud. i didn't use 6011 on that!! surly that piece of junk was shipped to china years ago so who knows how long it held.
