My local welding suplier recommended Stoody rod. I tried to run it with my Buzzbox. After a few minutes the rod would turn to cherry red. Checked with Stoddy who said that rod was best run on DC, something my AC buzzbox can't do. But for my toubles the Stoddy gave me a roll of hardfacing wire for my Hobart 175. It worked great and was very easy to use.
