CS6290VVC5/0 - Victor Cutskill 6290VVC-5/0 Harris Style Propane Machine Cutting Tip

Technical Overview of the Victor Cutskill CS6290VVC5/0

The Victor Cutskill CS6290VVC5/0 is a precision-engineered machine cutting tip designed to serve as a direct replacement for the Harris 6290VVC series. This specific model is sized at 5/0 (often denoted as 00000 in some nomenclature), indicating its application for extremely thin gauge materials, typically in the range of light sheet metal fabrication. The 'VVC' designation identifies this component as a high-speed machine cutting tip specifically calibrated for use with alternative fuels such as Propane and Natural Gas, rather than Acetylene.

Structurally, the tip utilizes a two-piece design standard for alternative fuel oxy-fuel cutting. The inner member is machined from brass and contains the splines that define the preheat gas flow, while the outer shell is chrome-plated copper. The separation of the inner and outer parts allows the preheat flame to anchor effectively at the face of the tip, which is critical given the lower flame propagation speed of propane compared to acetylene. The chrome plating on the outer shell serves a functional thermal purpose; it reflects radiant heat from the workpiece, thereby keeping the tip cooler during the prolonged duty cycles associated with automated machine cutting. This thermal management reduces the likelihood of flashback and extends the service life of the consumable.

In industrial MRO applications, the CS6290VVC5/0 is essential for automated cutting tables utilizing Harris-style torches. The 5/0 orifice size produces a very narrow kerf and minimizes the heat-affected zone (HAZ), which is paramount when processing thin substrates to prevent warping or distortion. The heavy preheat characteristic of the VVC design ensures rapid piercing and sustained cutting speeds, optimizing throughput in production environments. Operators should ensure that gas pressures are set according to the specific thickness of the material being cut, as the 5/0 size requires precise flow rates to maintain a stable cutting stream without blowing out the preheat flame or causing turbulence in the oxygen jet.
