Swirl ring: which way?

[KX9M]

Alessio… Here’s a good thread with pics and such… Read to end of thread… Helped me a bunch!!

Swirl ring direction matters more than I thought

You mean this picture. And this is only a few I had laying around. The first one on the left is for the Trafimet S45 torch, the second one is for the Tecmo IPT/PT torch the others are Chinese copy’s. [20190704_122149] You do know swirl rings wear out over time, as 70 to 75 psi of air flowing through them at 20,000 fps will take its toll on it. Just use a marker and mark the side you want toward the cutting tip.
