Plasma cutting torch assembly, as well as the use of wearing parts in a plasma cutting torch assembly

摘要

The invention relates to a plasma cutting torch arrangement with at least one plasma cutting torch, which is formed with a torch body, an electrode and a nozzle with a nozzle bore. With respect to a longitudinal axis, which is aligned perpendicularly through the nozzle bore, an outer contour AK of the plasma cutting torch is present in cross section. In at least one axial direction a smallest distance between the axis passing through the center of the nozzle bore of the nozzle longitudinal axis and the radially outer edge of the outer contour AK is maintained, the maximum 3/4 of the length of a maximum distance d between the through the center of the nozzle bore of the nozzle extending central longitudinal axis and the radially outer edge of the outer contour AK corresponds. The smallest distance c can also correspond to a maximum of 3/8 of the length of a largest distance b between two points of the outer edge of the outer contour AK whose virtual straight connecting line runs through the center of the nozzle bore of the nozzle extending central longitudinal axis.
