0333-0415 - Victor Size 4 GTB Propylene Gouging Tip for Machine Torches

Technical Overview of the Victor 4-GTB Bent Gouging Tip

The Victor 0333-0415 is a specialized Size 4 Gouging Tip from the GTB series, engineered specifically for use with Propylene fuel gas. This consumable is designed to facilitate the efficient removal of welds and metal preparation in industrial environments. Unlike standard straight tips, the GTB model features a bent configuration, making it particularly suitable for machine torch assemblies where specific angles of attack are required to maintain consistent gouging depth and profile. The tip is rated for effective gouging on material thicknesses ranging from 1/4 inch to 3/4 inch, covering a broad spectrum of structural steel and general fabrication requirements.

Thermodynamically, the tip is calibrated for Propylene, a fuel gas that offers a distinct heat distribution profile compared to Acetylene. The 4-GTB requires a fuel gas pressure setting between 8 and 10 PSIG to maintain a stable flame cone and optimal wash characteristics. Oxygen consumption is significant in gouging operations; this tip operates with a cutting/wash oxygen flow rate in the range of 210 to 250 SCFH, with preheat oxygen flow rates between 23 and 108 SCFH depending on the specific settings and depth of gouge required. Proper pressure management is critical: the manufacturer recommends a cutting and preheat gas pressure range of 30-65 PSIG to ensure the kinetic energy of the oxygen stream is sufficient to eject molten material effectively.

The physical construction of the tip adheres to Victor's rigorous standards for durability and flow dynamics. With dimensions of approximately 6.1 x 1.8 x 1.8 inches, the tip integrates seamlessly into compatible machine torch heads. The internal geometry is machined to minimize turbulence in the gas stream, ensuring a focused preheat flame and a coherent cutting stream. This precision is essential for "washing" welds—a process that demands control to remove the weld metal without damaging the base material excessively. The GTB series is widely utilized in sectors such as structural steel fabrication, repair and maintenance, and light fabrication where automated or semi-automated gouging is preferred over manual operations.

Operators and welding engineers should note that this tip is strictly for Propylene service. Attempting to use this specific nozzle geometry with alternative fuel gases like Acetylene or Natural Gas may result in flame instability, backfires, or inefficient gouging performance due to the differing burning velocities and BTU outputs of those gases. The 4-GTB represents a targeted solution for high-efficiency weld removal using alternative fuels.
