01Y39 - ESAB Oxweld C-37R Propane/Natural Gas Injector

Precision Gas Mixing for Machine Cutting

The ESAB 01Y39 LP/NG Injector is a critical component designed for the Oxweld C-37R machine cutting torch system. In oxy-fuel cutting, the method of mixing oxygen and fuel gas dictates the efficiency and quality of the flame. This specific injector is engineered to accommodate the fluid dynamic properties of Propane (LP) and Natural Gas (NG). Unlike acetylene, which is typically supplied at higher pressures, alternative fuels often require an injector-style (or low-pressure) mixing chamber to create a venturi effect. This effect draws the fuel gas into the high-velocity oxygen stream, ensuring a consistent and combustible mixture even at lower supply pressures.

Manufactured to ESAB's exacting OEM standards, the 01Y39 ensures that the C-37R torch operates within its specified parameters. The internal geometry of the injector is precision-machined to prevent flashbacks and sustain a neutral flame during long cutting operations. For industrial environments utilizing bulk natural gas or propane for cutting, this injector is the key interface that converts raw gas supply into a workable high-temperature preheat flame.

Constructed from high-quality brass, the component is built to withstand the thermal cycling and potential back-pressure inherent in heavy-duty industrial cutting. It serves as a direct replacement for worn or clogged injectors in existing C-37R setups, restoring the torch's ability to maintain the correct oxygen-to-fuel ratio required for clean, slag-free cuts.
