Plasma cutting machine normally applies to cut metal in electrical conductivity industrial according to an accuracy dimension and rapidly time consuming. A quality of this process is depend upon a cutting surface and kerf by controlling diameter of nozzle and size of electrode. Since kerf shape is crated base on nozzle diameter, while electrode is served plasma arc. This paper presents an investigating three cutting parameters: cutting speed, pressure gas, current ampere that affect to wear of plasma nozzle. The fixed variables are a plasma-cutting machine, Hypertherm powermax 45 xp, Bindee control CNC machine and specimens (100×100 mm.). The cutting speed was holed at 200, 300, 400 mm/min. The gas pressure was controlled at 6, 7, 8 bar. The current Ampere was handled at 40, 42, 45 A. The diameters of nozzle was measured using digital microscope. The experiments conducted based on ANOVA to establish the relationship of those parameters. The nozzle wear depended upon the current Ampere, the high gas pressure while the cutting speed was not effect to nozzle wear.
