Cutting Tip 6290Nx Size 3 For All Harris Torches Propane Only

Reliable Harris Style Propane Cutting Performance

The Generic 6290NX-3 Cutting Tip is a high-performance consumable designed to meet the rigorous demands of industrial metal cutting. Engineered as a direct replacement for Harris-style equipment, this tip is fully compatible with all standard Harris cutting torches and cutting attachments. It is specifically calibrated for use with Propane and Natural Gas, making it an economical choice for facilities that utilize these alternative fuel gases over acetylene.

This Size 3 tip is rated for cutting mild steel ranging from 2 inches to 3 inches in thickness. Whether you are processing heavy structural beams, dismantling machinery, or working in a scrap yard, the 6290NX-3 delivers a clean, consistent cut. The tip features a two-piece construction, which is essential for alternative fuels; the brass inner member contains splines for gas mixing, while the heavy-duty copper outer shell protects the assembly from intense reflected heat and slag.

Industrial Durability and Maintenance

In heavy industrial environments, consumables must be durable. The copper exterior of this nozzle provides excellent heat dissipation, reducing the risk of overheating during prolonged cuts. Furthermore, the two-piece design allows operators to easily separate the outer shell from the inner insert, making cleaning straightforward. Removing carbon buildup or slag from the splines restores optimal gas flow and flame characteristics, extending the lifespan of the tip and ensuring safety.

Optimized for Alternative Fuels

Unlike single-piece acetylene tips, the 6290NX series is designed with a recessed tip end and specific spline geometry to anchor the flame when using slower-burning gases like propane. This ensures a stable preheat flame that brings the steel to ignition temperature quickly, even on thicker plates. By choosing this generic equivalent, Josef Gas customers receive professional-grade cutting capability that integrates seamlessly into their existing Harris-style apparatus.
