19487 - Oxweld 4217 Series Acetylene Cutting Tip - Size 1

Technical Overview of the ESAB Oxweld 4217 Size 1 Cutting Tip

The ESAB Oxweld 4217 Series Cutting Tip (SKU: 19487) is a high-performance, one-piece nozzle engineered specifically for oxy-acetylene cutting applications. This Size 1 nozzle is calibrated to effectively cut mild steel with a thickness of approximately 3/4 inch (19mm). The 4217 series is a staple in the Oxweld product line, renowned for its robust construction and fluid dynamic efficiency.

Structurally, the nozzle is manufactured from a solid piece of high-conductivity copper. This one-piece design maximizes heat dissipation, keeping the tip cooler during prolonged operation and reducing the risk of flashback. The exterior is finished with a durable chrome plating. This plating serves a dual purpose: it protects the copper from oxidation and corrosion, and it provides a slick surface that resists the adhesion of molten slag and spatter, significantly extending the service life of the tip compared to bare copper alternatives.

Internally, the 4217 nozzle features precision-swaged gas passages. Unlike drilled passages which can leave rough interior walls causing turbulence, swaging creates mirror-smooth internal surfaces. This ensures laminar gas flow for both the preheat flames and the cutting oxygen stream, resulting in a stable, uniform flame cone and a clean, straight cut face. The Size 1 configuration typically operates optimally with oxygen pressures between 30-35 PSIG and acetylene pressures between 5-10 PSIG. It is fully compatible with standard Oxweld hand cutting torches including the C-32, C-66, C-77, and C-97 models, as well as CW-series cutting attachments.
