6290A-5 - Harris Style 6290-5 Acetylene Cutting Tip - 6 Inch Capacity

Precision Heavy-Duty Cutting for Industrial Applications

The Harris Style 6290 Size 5 Acetylene Cutting Tip is a premium-quality replacement consumable designed for the rigorous demands of heavy industrial cutting. Engineered to replicate the performance of the original equipment manufacturer specifications, this tip provides a reliable and stable flame for cutting carbon steel plates up to 6 inches (approximately 150mm) in thickness. It is an essential component for professionals in structural steel fabrication, shipyards, and demolition sectors who rely on the distinct thermal properties of oxy-acetylene cutting.

Constructed from a single piece of high-grade copper, the 6290-5 tip excels in thermal conductivity. This design feature is critical for heavy cutting operations, as it allows the tip to dissipate reflected heat rapidly, reducing the risk of overheating and prolonging the service life of the nozzle. The tip features a flat seating surface, a hallmark of the Harris system, which ensures a positive, gas-tight seal against the torch head. This minimizes the potential for leaks and dangerous flashbacks, providing a safer working environment for the operator.

The internal geometry of the tip is precision-drilled to optimize gas flow. The preheat orifices are calibrated specifically for acetylene, ensuring a high-temperature primary flame that brings the base metal to kindling temperature quickly. The central oxygen bore is sized to deliver a high-velocity stream of cutting oxygen, essential for blowing away the molten slag and maintaining a clean kerf through thick sections of steel. Whether you are severing I-beams or processing heavy scrap, this tip delivers consistent, high-quality cuts with minimal slag adhesion.

Compatibility is key in industrial MRO, and this tip is designed to fit all standard Harris-style cutting torches and cutting attachments (such as the 62-3, 73-3, and 142 series). By choosing this high-quality generic replacement, facilities can maintain their equipment's peak performance while managing operational costs effectively. It represents the intersection of value, safety, and heavy-duty capability.
