Thread: Excellent plasma cutting instruction videos

  1. #1

    Excellent plasma cutting instruction videos

    Here is a good video explaining why you get a taper on one side of the cut when plasma cutting. Keep in mind this is an Australian company. Being from Australia I think the direction needed is reversed from the northern hemisphere so you would go opposite what they say in the video. Still, it gives a good explanation of why it makes a difference.



    Another great video explaining the different types of dross and how to correct for them.

    Coriolis...no....swirl ring yes

    [QUOTE=Gadget;21394]Here is a good video explaining why you get a taper on one side of the cut when plasma cutting. Keep in mind this is an Australian company.

    Gadget these are truly excellent vids! But.....I doubted the Coriolis effect caused the swirl to be CW in Down-under, but it was a great beer drinking thought. So I tried my cutter, sure enough he was correct, even in direction. Rather than immediately think the earth had reversed axis I took apart my torch, and what did I find??? The swirl ring, and depending on how you put it in, the swirl can be CW or CCW See attached picture and look at the port, you can see that flipped one way it directs the air CW, the other way, CCW, the ring is symmetrical, so it dont care, only the air cares.
    cheers, and thanx for the vid links they were great!
