Had a shift last Tuesday where every pour came out clean as a whistle

I run the afternoon shift at a small shop in Akron. We were working on some gray iron castings for a local machine shop. Usually we have at least one mold that gives us trouble, but that day everything just clicked. The sand mix was perfect, the ladies stayed closed tight, and we didn't have a single cold shut or crack. The foreman even said "I don't know what you did different but keep doing it." It was one of those days that makes you forget about the bad ones. Has anyone else had a shift like that where everything just lined up?

Did you guys have a storm rolling through that day? I swear the barometric pressure drops before a storm always make the metal flow better.

Man I had the same thought last time we were working with some 316L. We had a cold front blow through and the pressure dropped like crazy and that weld just laid down perfect. @michaelw26 your theory makes sense to me, the puddle was way more fluid and stable than normal. I switched to a slightly longer arc and it just flowed out like butter, no fighting it at all.
