0333-0365 - Victor Size 1 MTHN Propane Machine Cutting Tip

Technical Overview of the Victor 1-MTHN Cutting Tip

The Victor 0333-0365 is a Size 1, Type MTHN cutting tip engineered specifically for high-speed machine cutting applications. This consumable is designed to operate with alternative fuel gases, specifically Propane and Natural Gas, making it a critical component for industrial fabrication environments seeking cost-effective and efficient cutting solutions. The MTHN series distinguishes itself with a two-piece construction, which is essential for alternative fuels; the outer shell and internal spline work together to stabilize the flame and optimize the preheat flame characteristics required for these slower-burning gases.

With a cutting capacity of 1-1/2 inches (approximately 38 mm), this tip is calibrated for precision work on structural steel and plate. The operational parameters are distinct: it requires a cutting oxygen pressure range of 85-95 psig to maintain the high-velocity oxygen stream necessary for ejecting molten slag at speeds of 12 to 16 inches per minute. The preheat oxygen requirement stands at 30-35 psig, ensuring sufficient thermal energy is delivered to the base metal before and during the cut. The fuel gas pressure is rated for low-pressure delivery (8 oz +), typical of injector or positive pressure machine torch setups designed for alternative fuels.

Manufactured from high-grade brass, the 1-MTHN ensures thermal conductivity and resistance to deformation under the high-heat conditions of continuous machine cutting. The physical dimensions (0.7 x 0.8 x 3.2 inches) ensure compatibility with standard Victor-style machine torch retainers. This tip is ideal for automated setups in shipyards, structural steel plants, and heavy equipment repair facilities where consistency and edge quality are paramount.
