2228300 - ESAB Oxweld PM-300 Machine Torch 33.5-Inch 2-Inch Barrel

Technical Overview of the ESAB Oxweld PM-300 Machine Torch

The ESAB Oxweld PM-300 (SKU: 2228300) represents the pinnacle of heavy-duty oxy-fuel machine cutting technology. Engineered for industrial environments requiring extreme cutting capacities, this torch is designed to sever steel sections up to 40 inches (1016 mm) in thickness. The unit features a substantial 33-1/2 inch length, providing necessary clearance and heat dissipation for the machine carriage during prolonged high-heat operations. Central to its mechanical architecture is the 2-inch diameter barrel, a standard specification that ensures compatibility with a wide array of industrial gantry and tractor mounting systems, offering superior rigidity compared to smaller barrel variants.

A defining technical characteristic of the PM-300 series is the "post-mix" gas distribution system. Unlike pre-mix torches where fuel and oxygen combine within the torch body, the PM-300 mixes gases externally at the nozzle exit. This engineering choice effectively eliminates the possibility of flashback occurring within the torch barrel or supply lines, significantly enhancing operational safety. This design is particularly critical when working with high flow rates required for deep cutting. The torch supports multiple cooling methodologies, including convection, forced air, and water cooling, allowing engineers to tailor the thermal management system to the specific duty cycle and ambient conditions of the cutting facility.

The PM-300 is optimized for high-speed shape cutting and automatic cut-off applications. The design incorporates a high stand-off distance, which serves a dual purpose: it protects the nozzle from molten splash and slag blowback, and it maintains the integrity of high-speed cutting tips over extended production runs. While the post-mix design precludes the ability to pierce plates directly—requiring edge starts or pre-drilled pilot holes—the trade-off yields a robust, virtually maintenance-free tool for processing heavy ingots, risers, and massive structural components. The 2228300 model is supplied as a dedicated unit ready for integration into complex automated cutting systems.
