We have a supply house here in town that sells cast iron ornamental stuff which I want to use to make a mailbox post. I was going to use 3/4" square steel posts and weld this ornamental stuff in the middle. Will there be a problem doing this with a MIG welder? I read in the archives about the problems of welding cast iron, but the salesman at the place that sells this stuff assures me that it'll weld right up. Is he lying to me?
Thanks in advance!
