6290G-1 - Harris Style 6290G Size 1 Acetylene Gouging Nozzle

Technical Overview of the 6290G-1 Gouging Tip

The Generic 6290G-1 Gouging Tip is a specialized oxy-fuel consumable designed for the controlled removal of metal using an acetylene gas supply. Unlike standard cutting tips which utilize a high-velocity oxygen jet to sever material completely, this gouging tip employs a modified bore geometry. This design produces a lower-velocity, voluminous oxygen stream that oxidizes and washes away molten metal, creating a smooth groove rather than a through-cut. This makes it an essential tool for industrial maintenance, repair, and fabrication environments where weld removal or joint preparation is required.

Manufactured to replicate the specifications of the industry-standard Harris 6290 series, this tip features a flat seat sealing surface. This ensures full compatibility with a wide range of Harris-style cutting attachments and straight torches. The tip is machined from a high-conductivity copper alloy, which is critical for managing the intense reflected heat generated during the gouging process. The single-piece construction simplifies maintenance and ensures a robust service life under rigorous workshop conditions.

The "Size 1" designation indicates the orifice diameter and flow capacity, making this specific model suitable for light-to-medium gouging applications. It allows the operator to precisely control the depth and width of the groove, which is particularly important when removing surface defects or preparing cracks for re-welding. Proper pressure settings are vital for optimal performance; typically, gouging requires lower oxygen pressures than cutting to prevent blowing through the workpiece. This tip is strictly for use with Acetylene and Oxygen; the use of alternate fuel gases with this specific tip design may result in flame instability or insufficient preheat intensity.

In MRO (Maintenance, Repair, and Operations) settings, the 6290G-1 is frequently utilized for back-gouging welds to ensure complete joint penetration, removing temporary lifting lugs, or excavating worn metal on heavy machinery prior to hardfacing. Its compatibility with standard Harris equipment makes it a versatile addition to any professional welder's toolkit.
