  • Page 40: G - Water Vortex Fittings

    8695 9064 / L G - WATER VORTEX FITTINGS External water vortex : Water supply of this vortex is independent of the torch. This fitting is used to implement the plasma processes : - mainly nitrogen, - as well as industrial air or oxygen. The water vortex allows significant reduction in annoyances because of the fact that the cut generally takes place under water.
  • Page 41 G - WATER VORTEX FITTINGS 8695 9064 / L CUTTING APPEARANCE (CLEARANCE) : The gas vortex and the water vortex both rotate in the same direction (clockwise, to the right) and these rotations give a special shape to the cut. The right rotation of the water and gas vortex results in the right side A of the kerf being practically vertical and the left side B inclined.
