current position：Information and data>What factors affect the plasma arc voltage
(1) It is related to the structure of the spray gun, especially the structure and geometric size of the nozzle,
(2) It is related to the way of air intake. The working voltage of the swirl intake mode is higher than that of the DC intake mode.
(3) It is related to the flow and type of plasma gas (main gas and secondary gas). In particular, the flow of secondary gas (usually hydrogen or helium) has a significant effect on the arc voltage.
(4) The size of the gap between the nozzle and the cathode is related. The gap is large and the working voltage is high.
