0380-0208 - Victor MT-5 Dupli-Cutter Machine Torch, 3-Hose, 8.5-Inch

Victor 0380-0208 MT-5 Technical Overview

The Victor MT-5 (0380-0208) is a straight-barrel machine cutting torch designed for use with motorized cutting carriages and shape-cutting machines. It belongs to the Victor Three Hose division, indicating it requires a separate supply for cutting oxygen, preheat oxygen, and fuel gas. This configuration is preferred in automated applications to prevent preheat starvation when the cutting oxygen valve is opened.

Key Specifications

• Total Length: 8.5 inches (215.9mm)
• Barrel Length: 5.38 inches (136.77mm)
• Barrel Diameter: 1.38 inches (35.1mm)
• Racking Length: 5.38 inches (136.7mm)
• Cutting Range: Up to 7 inches (177.8mm)

Operational Characteristics

This model is a valveless torch, meaning gas flow control (on/off and pressure adjustment) must be managed remotely via the cutting machine's manifold or solenoid system. This reduces the weight on the torch arm and eliminates the risk of accidental valve adjustments during operation. The torch is equipped with a standard gear rack running along the barrel, facilitating smooth vertical adjustment via the machine's pinion gear mechanism.

Consumables and Gas Compatibility

The MT-5 utilizes Victor Series 1 cutting tips. The specific tip selected determines the fuel gas compatibility. The torch itself is rated for use with all standard fuel gases at pressures of 2 PSI and above. Operators should ensure that the correct tip style (e.g., Type 101 for Acetylene, Type GPN for Propane/Natural Gas) is installed to match the fuel supply. The 3-hose connection ensures that preheat flames remain stable even when the high-velocity cutting oxygen stream is engaged.

Installation Notes

Mounting the torch requires a standard machine torch holder capable of clamping a 1.38-inch barrel. The 3-hose inlet connections are standard "B" size fittings (9/16"-18 threads), with the fuel gas connection having left-hand threads (notched) and the oxygen connections having right-hand threads. Proper flashback arrestors should be installed at the regulator or manifold end of the hose assembly for safety.
