Has anyone arc welded using 308 SS rods? I have some Blue Demon 308 I got from McMaster-Carr and have a very hard time getting the bead to look nice. It doesn't seem to wet out the base metal very well. And yes, I have tried turning up the heat. It ends up being lumpy and porous looking. The slag is tough to remove also. I saw some threads on Welding Web, Everlast, and Hobart (maybe) where the guys had bad things to say about Blue Demon 7018.
A guy at work gave me some Blue Lightning rod to try. It's listed as a rod for joining dissimilar alloys. The MSDS lists it as having Iron, Chromium, Nickel, and Manganese in it. So it's kinda like stainless steel. This rod runs easier than the 308 I have. The beads end up looking really nice and smooth and the slag chips off easily too.
