CS6290NX6 - Victor Cutskill 6290NX-6 Propane Cutting Tip for Harris Torches

Technical Overview of the Victor Cutskill CS6290NX6

The Victor Cutskill CS6290NX6 is a premium aftermarket cutting tip designed to be fully compatible with Harris-style oxy-fuel cutting torches. This specific model belongs to the 6290NX series, which is engineered exclusively for use with alternative fuel gases such as Propane and Natural Gas. Unlike acetylene tips, the 6290NX series utilizes a two-piece construction consisting of a brass inner member with splines and a copper outer shell. This design creates a recess at the tip end, which is critical for anchoring the flame when using fuels with lower flame propagation speeds like propane.

The "Size 6" designation indicates a large orifice diameter intended for heavy industrial applications. Specifically, this tip is rated for cutting mild steel ranging from approximately 6 inches (150mm) to 8 inches (200mm) in thickness. Achieving quality cuts on material of this magnitude requires precise gas flow and pressure management; typically, oxygen pressures in the range of 70-80 PSI are recommended for the cutting stream, while fuel gas pressures should be maintained between 5-15 PSI depending on the specific torch setup and hose length.

Manufactured to strict tolerances, the CS6290NX6 ensures a concentric flame pattern and a high-velocity oxygen stream, resulting in a narrow kerf and minimal slag adhesion. The separation of the inner and outer parts allows for easy cleaning and maintenance, although care must be taken not to damage the splines which control the preheat flame distribution. This tip is an essential consumable for fabrication shops, scrap yards, and industrial maintenance teams utilizing Harris equipment with cost-effective alternative fuels.
