17268 - Purox Style W-300 Welding Tip Size 12

Precision Engineering for Heavy Fabrication

The ESAB Purox W-300 Welding Head, Size #12 (SKU: 17268), represents the pinnacle of oxy-fuel component engineering. Designed specifically for the legendary Purox W-300 and W-400 series torch handles, this welding head is engineered to meet the rigorous demands of heavy industrial fabrication, structural steel work, and maintenance operations. The #12 size designation indicates a large orifice capability, suitable for welding thick metal sections where deep penetration and substantial heat input are required. Unlike multi-piece assemblies that can suffer from gas turbulence, this head features a single-piece swaged copper construction. This design choice not only enhances the structural integrity of the tip but also maximizes thermal conductivity, keeping the tip cooler during extended operation and reducing the risk of overheating.

The internal geometry of the 17268 welding head is precision-bored to ensure laminar gas flow. This results in a flame that is both stable and easily controllable, providing the operator with a defined neutral cone essential for high-quality welds. The smooth interior finish minimizes carbon buildup and turbulence, which are common causes of flame distortion in inferior tips. For industrial MRO professionals, the reliability of the Purox W-300 series is unmatched; this replacement head restores your torch to factory-specification performance, ensuring that gas mixing occurs safely and efficiently within the handle and mixer assembly.

Safety and longevity are core attributes of the ESAB Purox line. The heavy-wall copper tubing used in this welding head is resistant to the harsh environments of shipyards, rail yards, and construction sites. The seating area is machined to exact tolerances to ensure a leak-proof seal with the torch handle, preventing dangerous gas leaks. Whether used for fusion welding of heavy pipe, pre-heating thick plate for bending, or general maintenance repairs, the Size #12 W-300 head delivers consistent BTUs. It is optimized for Acetylene gas, taking advantage of acetylene's high flame temperature to reduce work time and improve weld puddle fluidity.

Maintenance of the tip is straightforward, requiring only standard tip cleaners to maintain the orifice shape. The elongated design provides excellent visibility of the work area, allowing the welder to manipulate the puddle with precision even on complex joints. By choosing genuine ESAB parts, operators ensure compatibility and safety, maintaining the UL-listed performance standards of their oxy-fuel equipment.
