1501370 - Harris 6290-1VVC High-Speed Machine Cutting Tip, Size 1, Propane/Natural Gas

Precision High-Speed Machine Cutting

The Harris Model 6290-1VVC is a premium machine cutting tip engineered for industrial environments requiring precision, speed, and efficiency. Designed specifically for use with low-cost alternative fuel gases such as propane and natural gas, this tip represents a significant upgrade in automated cutting technology. The VVC series is distinguished by its ability to support high-speed cutting operations, which directly translates to increased throughput in fabrication shops, shipyards, and manufacturing facilities.

Advanced Construction and Materials

This cutting tip features a robust two-piece construction, a hallmark of high-performance alternative fuel tips. The internal shell is machined from high-quality brass, ensuring consistent gas flow and optimal mixing characteristics. The outer shell is finished with an electroless nickel plating. This plating is not merely cosmetic; it serves a critical functional role by reflecting radiant heat away from the tip during prolonged machine cuts, thereby keeping the tip cooler and extending its service life. Furthermore, the nickel surface resists the adhesion of spatter and slag, ensuring that the tip remains clean and the preheat orifices remain unobstructed for longer periods.

Operational Efficiency

The geometry of the 6290-1VVC is optimized to minimize kerf width. A narrower kerf means less material is wasted and, more importantly, higher cutting speeds can be achieved. By increasing the travel speed of the machine torch, the total heat input into the base metal is significantly reduced. This reduction in heat input is crucial for maintaining dimensional accuracy, as it minimizes thermal distortion and warping of the plate. The specific .088 cup depth is engineered to stabilize the preheat flame, allowing for aggressive cutting speeds without loss of the cut.

Application and Compatibility

This Size 1 tip is strictly for use with Propane or Natural Gas and must not be used with Acetylene. It is compatible with standard Harris-style machine cutting torches. The tip is permanently engraved with its model number and size, facilitating easy identification and inventory management in busy production environments. Whether used for straight-line cutting, beveling, or complex shape cutting, the 6290-1VVC delivers high-quality edges that often require little to no post-cut machining or grinding.
