0380-0228 - Victor MT318AV 3-Hose Machine Torch, 14-Inch, Acetylene

Technical Overview of the Victor MT318AV Machine Torch

The Victor 0380-0228 MT318AV is a high-specification machine cutting torch belonging to the renowned MT 300 series. Engineered for precision automated cutting environments, this torch features a 'straight-through' design architecture. This internal configuration is critical for minimizing gas turbulence as the fuel and oxygen travel through the torch body, resulting in a significantly more stable flame and a cleaner cut face compared to standard designs. The unit is configured as a three-hose system, distinct from two-hose models, allowing for the independent supply and control of preheat oxygen, cutting oxygen, and fuel gas. This separation is vital for machine applications where remote regulation of the cutting oxygen stream is required for piercing and ending cuts smoothly.

Mechanically, the torch boasts a total length of 14 inches (355.6mm) with a dedicated barrel length of 10 inches (254mm). The racking length is specified at 7 inches (177.8mm), providing ample room for mounting clamps, although this specific SKU (MT318AV) is noted as being supplied without a gear rack, making it suitable for smooth-bore holders or custom mounting solutions. The torch is rated for a substantial cutting capacity of up to 12 inches (304.8mm) when equipped with the appropriate Series 1 cutting tips. It is optimized for Acetylene gas but retains the versatility to be used with other pressurized fuel gases such as Propane or Natural Gas by simply changing to the correct tip type.

A defining technical characteristic of the MT318AV is the absence of a high-pressure cutting oxygen valve on the torch body itself. This design choice is intentional, intended for systems where the cutting oxygen is actuated via a solenoid or remote valve on the cutting machine's manifold. This reduces the weight and complexity of the torch head and prevents accidental manual interference during automated cycles. The brass construction ensures thermal stability and resistance to flashback damage, maintaining dimensional accuracy over long duty cycles.
