Plasma Cutting Torch

Cut quality depends to a high degree on the distance between the torch tip (nozzle) and the surface of the sheet we work on. The Plasma Arc is not cylindrical, it gets narrower in its upper and lower edges; consequently, when we cut too high the cut is performed by its lower edge and vice versa. In both cases the “sides” of the cut are not square. Please see our photo to the right: the torch is too high and the cut is “conical”. It is only when the cut is performed by the middle section of the Arc that we achieve optimal cuts. Here the presence of a digital Arc Control system interconnected to the CNC is absolutely important. It must be able to interact with the CNC for the ideal Torch Height to be maintained regardless the torch velocity changes and eventual holes in the job
