Plasma Bore Welding Torch DNPT30018-HQ
Product Advantages
300A plasma bore welding gun consists of three parts: upper gun body, lower gun body and insulator. The upper gun body is used to fix and install the tungsten electrode and connect the water and electric joints; the lower gun body fixes and installs the nozzle and constitutes the water-cooled cavity of the nozzle and connects the joints of the water, electric, gas and powder pipelines; the insulator ensures the insulation of the upper and lower gun bodies and connects the fixing of the upper and lower gun bodies. The protective gas of the gun body completes the gas diffusion inside the gun body to form a uniform protection.
