Oxweld 1502 Series Acetylene Cutting Tip - Size 12

Heavy-Duty Performance for Professional Welders

When the job demands cutting through heavy steel plate, professional welders turn to the ESAB Oxweld 66Z63 Cutting Tip. Part of the legendary 1502 Series, this Size 12 nozzle is a workhorse designed for acetylene cutting applications requiring depth and speed. Capable of severing steel up to 4 inches thick, it is an essential consumable for heavy equipment repair, structural steel erection, and industrial demolition projects.

The 66Z63 distinguishes itself with its one-piece copper construction. In the rough-and-tumble world of field welding and cutting, durability is non-negotiable. This solid copper design resists damage from accidental drops and withstands the high reflected heat generated when piercing thick plates. The tip's high thermal conductivity pulls heat away from the orifice face, preventing the preheat holes from melting or deforming, which is a common failure point in inferior multi-piece tips.

Efficiency in cutting is driven by gas flow dynamics. The Oxweld 1502 series features a swaged interior that accelerates the cutting oxygen stream without creating turbulence. This results in a long, stable cutting jet that maintains its shape deep into the cut, ensuring straight edges and minimal dross. The preheat flames are shaped by precision-machined splines, providing an even ring of fire that quickly brings the base metal to ignition temperature, even on rusty or mill-scale covered surfaces.

This tip is designed to fit the industry-standard Oxweld torch head configuration. It utilizes a reliable metal-to-metal seat, ensuring a safe and secure connection to torches like the CW-23, CW-300, and other Oxweld-style handles. By removing the reliance on perishable gaskets, ESAB ensures that your torch remains safe and operational in extreme conditions. Equip your torch with the 66Z63 to experience the difference that genuine Oxweld engineering makes in cut quality, speed, and consumable life.
