0333-0367 - Victor 3-MTHN Propane Machine Cutting Tip Size 3

Victor 3-MTHN High-Speed Machine Cutting Tip (0333-0367)

The Victor 3-MTHN Cutting Tip (SKU: 0333-0367) is a precision-engineered consumable designed specifically for high-speed machine cutting applications. Part of the Victor Series 1 family, this tip is optimized for use with Propane and Natural Gas, offering a cost-effective and clean-burning alternative to acetylene for automated cutting processes. The "MTHN" designation indicates a high-speed tip design, capable of maintaining stable preheat flames and powerful cutting oxygen streams even at accelerated travel speeds.

Technical Specifications and Performance

This Size 3 tip is rated for cutting material thicknesses up to 2-1/2 inches (approx. 64 mm). It features a two-piece construction, which is standard for alternative fuel tips. The outer shell and inner member create a recessed tip end that protects the flame from blowing out and allows for the specific combustion requirements of propane and natural gas. The tip requires a cutting oxygen pressure range of 85-95 psig and a preheat oxygen pressure of 30-35 psig to achieve optimal performance. Fuel gas pressure should be maintained at 8 oz or higher depending on the specific setup.

Industrial Applications

Designed for industrial and general fabrication, the 3-MTHN is ideal for structural steel fabrication, repair, and maintenance operations where machine torches are utilized. The high-speed capability allows fabrication shops to increase throughput without sacrificing cut quality. The tip fits standard Victor machine torches compatible with Series 1 consumables, ensuring broad compatibility with existing equipment in the field. Its brass construction ensures excellent heat dissipation and resistance to spatter adhesion, prolonging the service life of the tip in demanding continuous-duty cycles.

Operational Parameters

Operators should adhere to the specific gas consumption rates for optimal efficiency. This tip typically consumes 285-320 cfh of cutting oxygen and 12-65 cfh of fuel gas. Proper seating of the two-piece assembly is critical for safety and performance; ensure both the inner and outer members are free of debris before installation into the torch nut.
