Thank you.. I just tried the welder and oiled the feed drives a bit and it is running better than the Harbor Freight USED TO.. Already got it all ugly. I am still going to have fun with it.. Welds better and DID NOT pop a fuse YET. Thanks again.. I fear your option may be the best one.. I might even be able to "beef it up" around the crack and (please refrain) make it stronger than original.
