65Z45 - Oxweld 1808 Series Propane Cutting Tip - Size 40

High-Performance Propane Cutting Nozzle

The ESAB Oxweld 1808 Series Cutting Tip (Size 40), identified by SKU 65Z45, is a premium consumable engineered for industrial oxy-fuel cutting applications. Specifically designed for use with alternate fuels such as Propane, Natural Gas, and MAPP, this nozzle allows fabricators to leverage the cost benefits of these gases while maintaining high cutting speeds and quality. The 1808 series is a staple in the heavy industrial sector, known for its reliability in scrap yards, structural steel fabrication, and maintenance operations.

Technically, the 65Z45 features a two-piece construction, consisting of a brass inner member with splines and a copper outer shell. This design is critical for alternate fuels, as it creates a recess that anchors the flame, ensuring stability even at high flow rates. The "Size 40" designation indicates a large orifice capable of cutting steel plates approximately 4 inches (102mm) thick. It offers a medium preheat pattern, which balances gas consumption with the heat input required to start cuts on dirty or scaled plates efficiently.

This tip is fully compatible with standard Oxweld torch handles, including the C-32, C-66, C-77, and C-97 series. The precision manufacturing of the internal gas passages ensures a uniform oxygen stream, resulting in smooth cut faces and minimal slag accumulation. Maintenance personnel will appreciate the separability of the inner and outer parts, which simplifies the cleaning of carbon deposits and slag from the preheat slots, significantly extending the lifespan of the consumable compared to single-piece acetylene tips.
