0380-0225 - Victor MT 318N 3-Hose Machine Torch for Propane/Natural Gas

Technical Overview of the Victor MT 318N Machine Torch

The Victor MT 318N (SKU: 0380-0225) is a premium industrial-grade machine cutting torch designed for mechanized cutting applications requiring precision and power. Part of the renowned MT 300 series, this torch is engineered with a "straight-through" design that significantly reduces gas turbulence compared to standard tube-mix torches. This fluid dynamic optimization is critical when working with alternative fuels such as Propane, Natural Gas, and LP, ensuring a stable flame and superior cut quality on material thicknesses up to 12 inches (304.8 mm).

This specific model features a 3-hose configuration. In three-hose systems, the cutting oxygen is supplied through a separate line from the preheat oxygen and fuel gas. This separation allows for independent control of the cutting stream, providing the operator with the ability to fine-tune the flame for rapid starts and high-speed cutting without starving the preheat flame. The torch barrel has a diameter of 1.38 inches (35.1 mm) and a length of 18 inches, making it compatible with a wide range of mounting clamps and bug-o systems. Note that this specific SKU (0380-0225) is supplied without a gear rack, offering a smooth barrel profile for friction-style clamping mechanisms.

Safety and durability are paramount in the MT 318N design. The torch body and head are constructed from solid brass, providing excellent resistance to heat and mechanical impact. Internally, the torch is equipped with reverse flow check valves. These safety devices feature a spring-loaded disk assembly that compresses under normal flow but seals tight against the seat if reverse flow is detected, effectively preventing dangerous gas mixtures from entering the hose lines. The torch utilizes standard Victor Series 1 cutting tips, ensuring easy availability of consumables for various metal thicknesses.
