Many, many, years ago when I learned to weld I was told to use a can of7018 that had been left open for a long time, and not to sweat when and if the flux flaked off. Didn't do any welding worth bragging about since then. Starting up to bring my skills back recently, I used 6013, and my welds looked like crap, and with some effort, they looked less and less like crap, but it was hard to avoid spilling a little crap in there. I bought some 7018 the other day and finally cracked it open and laid some beads down on a project. Holy cow, what a difference! It was beautiful! Why didn't I do this sooner? I haven't done anything other than simple beads with just a few rods burned up, but what are the reasons I shouldn't use this rod for all my mild steel projects? Any particular applications to avoid? The flux "cup" makes it a bit of a pain to restart, but a quick scrape on the concrete and problem solved, although not quite as easy to restart as 6013.
