1500860 - Harris 6290 Size 3 Acetylene Cutting Tip

Precision Cutting with the Harris 6290-3

The Harris Model 6290-3 is a premium single-piece hand cutting tip engineered for professionals who demand reliability and precision in their oxy-acetylene operations. Manufactured to exacting standards in Poland, this tip is designed specifically for use with acetylene gas, leveraging the fuel's high flame temperature for efficient piercing and cutting. The 6290-3 is categorized as a Size 3 tip, optimized for cutting steel thicknesses ranging from 2 inches to 3 inches (approximately 50mm to 75mm). This range makes it an essential consumable for heavy fabrication shops, structural steel work, and industrial maintenance departments where medium-to-heavy plate cutting is routine.

Constructed from a single piece of high-quality copper, the 6290-3 offers exceptional thermal conductivity. Unlike two-piece tips that can separate or overheat, the solid copper design dissipates heat rapidly, prolonging the life of the tip even under sustained high-temperature use. The internal geometry is precision-drilled to ensure a laminar gas flow, resulting in a stable preheat flame and a powerful cutting oxygen stream. This model features a "General Preheat" pattern, which provides a balanced flame suitable for cutting relatively clean steel surfaces without excessive slag accumulation.

Compatibility is a key strength of the 6290 series. This tip fits all standard Harris cutting torches, attachments, and compatible Harris-style equipment. The tip is clearly engraved with its model number and size, allowing operators to quickly verify they have the correct equipment for the job. Whether you are processing scrap, fabricating structural beams, or performing critical repairs, the Harris 6290-3 delivers the consistent performance required for high-quality cuts.

Technical Excellence

The engineering behind the 6290-3 focuses on gas efficiency and cut quality. The seating surfaces are machined to tight tolerances to prevent leaks at the torch head, ensuring safety and preventing gas wastage. The single-piece design also simplifies maintenance, as there are no inner and outer sleeves to align or clean separately. By choosing genuine Harris consumables, users ensure their equipment operates at peak efficiency with the flow rates and flame characteristics intended by the manufacturer.
