That SLAG, is 100 precent proof that its absolute crap. If you back purge stainless, its a very nice and smooth inside weld. If you don’t, it looks like shit, and its a whole lot more crack prone. If thats the shit they sell, i wouldn’t recomend anyone to them, and they need to be shot. 10 bucks says its made overseas, cause if theres guys in the states too fuckin cheap to put at least some SOLAR flux on the inside, then they ruin what little of a name american quality had.
