Spent 3 years grinding my tungsten wrong before a welder in Tulsa set me straight
Turns out you're supposed to grind lengthwise, not spin it around like a pencil sharpener. That guy showed me how it changes the arc stability, and I haven't had contamination issues since. Anyone else get taught bad habits early on?

I mean I remember reading some forum post where a guy broke down the science behind it. Apparently grinding across the grain leaves these little grooves that can trap gas or impurities, and spinning it around just makes it worse. Idk, maybe it's just me but I've always been paranoid about contamination ever since I heard that. That Tulsa guy sounds like he knows his stuff though, three years is a long time to be doing it backwards.

Man honestly I feel like people overthink this stuff way too much. Like yeah sure maybe grinding across the grain makes some little grooves, but are you really gonna taste the difference? I doubt it. three years doing it backwards and that Tulsa guy is still kicking, so clearly it ain't that big of a deal. People act like one wrong move and your whole batch is ruined, but in reality most of this stuff is just bro science passed around forums.
