6290G-2 - Harris Style 6290G Size 2 Acetylene Gouging Nozzle

Technical Overview of the 6290G-2 Gouging Tip

The 6290G-2 is a specialized oxy-fuel consumable designed for gouging applications, specifically engineered to be fully compatible with Harris-style torch systems. Unlike standard cutting tips which are designed to sever material with a straight, narrow kerf, this gouging tip features a specific bore geometry and preheat arrangement intended to wash away molten metal, creating a clean groove. This makes it an essential component for industrial maintenance, repair, and fabrication environments where weld removal, crack preparation, or defect excavation is required.

Manufactured from high-grade copper alloy, the tip is built to withstand the intense reflected heat generated during the gouging process. The internal configuration of the 6290G-2 ensures a stable preheat flame using acetylene gas, which provides the high flame temperature necessary for rapid initiation of the gouging action. The oxygen stream is diffused slightly compared to a cutting tip, allowing the operator to control the depth and width of the groove effectively. This specific model is a Size #2, offering a balanced performance suitable for medium-depth gouging on carbon steel plates and structures.

The tip utilizes the standard Harris-style seating mechanism, typically involving a metal-to-metal seal or O-ring configuration depending on the specific torch head design, ensuring a secure and leak-free connection. It is designed for use with oxygen and acetylene only and should not be used with alternative fuel gases such as propane or propylene, as the combustion characteristics and tip recession are specifically calibrated for acetylene. Industrial operators can rely on this generic replacement part to deliver consistent performance comparable to OEM specifications.
