I mentioned a while ago that Fab Shop would be publishing an article about welding 4130 steel, written by a specialist at Hobart. It's in the current issue:
It was being edited as I made my exit from the magazine, so it's missing a couple of things I had wanted to include, and I didn't do the final edit. But it's still helpful to anyone who wants some expert advice on welding the stuff. Blaine Guy knows what he's saying.
