0333-0353 - Victor 0-MTH-P Propylene Machine Cutting Tip Size 0

Precision High-Speed Machine Cutting with Victor MTHP Series

The Victor 0-MTH-P Cutting Tip (0333-0353) represents the pinnacle of gas distribution technology for automated cutting processes. Engineered specifically for use with Propylene and MAPP gases, this Size 0 tip is designed to deliver high-velocity cutting oxygen streams, enabling travel speeds of 18 to 28 inches per minute on 3/4-inch mild steel plate. Unlike standard hand-cutting tips, the MTHP series is optimized for the rigorous demands of machine torches where consistency, kerf quality, and slag minimization are critical operational metrics.

This two-piece tip features a brass outer shell and a splined inner member, a design architecture that is essential for alternative fuels like Propylene. The separation allows for the precise mixing of preheat oxygen and fuel gas at the tip face, preventing flashback and ensuring a stable, high-temperature preheat flame. The 0-MTH-P requires a cutting oxygen pressure of 85-95 psig, significantly higher than standard tips, to maintain the momentum of the oxygen stream necessary for high-speed oxidation and material removal. Preheat oxygen should be regulated between 30-35 psig, with fuel gas pressures as low as 8 oz/in² (approx 0.5 psig), making it efficient in terms of gas consumption while maximizing thermal output.

Industrial fabricators relying on CNC or track-torch setups will appreciate the dimensional accuracy of the 0-MTH-P. The tip maintains a focused flame cone that reduces the heat-affected zone (HAZ) and produces square top edges with minimal rounding. With a total oxygen consumption rate of 110-120 cfh during the cut, this component balances performance with efficiency. Proper maintenance of the seating surfaces and regular inspection of the orifices will ensure a long service life and repeatable cutting parameters across production runs.

Technical Specifications and Operational Parameters

Integrating the 0-MTH-P into your cutting system requires adherence to specific pressure settings to achieve the rated performance. The tip is rated for a metal thickness of approximately 3/4 inch (19mm), though it can be adapted for slightly thinner materials (down to 3/8 inch) by adjusting travel speed. The high-speed divergence design of the oxygen bore ensures that the cutting stream remains laminar over a greater distance, improving cut straightness on thicker sections.
