Mitch & Tom,
I read in the genuine VICTOR welding manual that turning the gas off first usually causes a pop that can back up soot & carbon in the mixing chambers & is tough on the large & the small "O" rings where the tip or the cutting head seals to the mixing body. (Buster just said, "SO THERE!) If it makes you feel better, I've always done it BASSACKWARDS in my mixed & colorful past. Gotta' read more! LOL Bill W.
