Abstract
This invention relates to a nozzle structure for a plasma cutting gun, to prevent nozzle of the spraying head from melting, burning or collapsing during the process of plasma cutting, thereby eliminating frequent replacement while ensuring excellent cutting quality. In the invention, an opening is provided to the nozzle of a spraying head of a plasma cutting gun, and serves to assemble a heat-resistant and heat-insulation spray head, such that when the plasma is injected from the spray head, the pray head can protect the inner wall section of the entire nozzle from being melted, burned and damaged by the high-temperature plasma and prevent escape of pressurized flow leaked from collapsed periphery resulting in non-smooth electric arc.
