Features: High efficiency plasma cuttings nozzles with contact styles design ensures rapid metal slicing and extended durability, crafted from premium copper for superior thermals conductivity. The patented gourd shaped nozzle enhances gas cooling efficiency while concentrating flame output, with imported hafnium electrodes and thickened copper construction for penetration power. Ideal for professional metalworkers, industrial maintenance, and welding specialists requiring precise cuttings tool for heavy duty fabrication projects. Perfect for scrap metal recycling operations, steel plate modification in workshops, or onsites repair tasks where contact cuttings and edges start arcs techniques is essential. Engineered with wear resistant hafnium cores and optimized airflows channel, these nozzles deliver vertical flame stability even during prolonged highly temperature cuttings.
