Hard drawn, electrolytic, tough pitch copper used in one-piece nozzles withstands heat and wear outlasts any copper alloy nozzle. Precise CNC controlled drilling process ensures consistency in performance and quality. One-piece tips have triple swaged interior gas passages are mirror smooth with internal angles rounded for non-turbulent, more efficient gas flow clean, smooth cuts with minimal kerf. Preheat ports are closely spaced around cutting orifice for greater concentration of preheat flames. Long, parallel preheat passages permit re-dressing tips without affecting performance. One-piece tips are a single piece of solid copper provide maximum cooling recommended always for acetylene and for other fuel gases when heat exposure is unusually severe. Two-piece tips recommended for high efficiency with alternate fuels solid copper, heavy-wall external sleeve and brass internal sections can be ordered separately to minimize replacement cost.
