CS62901 - Victor Cutskill 6290-1 Harris Style Acetylene Cutting Tip, Size 1

Technical Overview: Victor Cutskill CS62901

The Victor Cutskill CS62901 is a precision-engineered cutting tip designed to replicate the performance and fitment of the industry-standard Harris 6290-1. Manufactured by Victor Technologies, this consumable is part of the Cutskill line, which aims to provide professional-grade quality at a value-oriented price point. The CS62901 is specifically calibrated for Oxy-Acetylene cutting processes, utilizing the distinct preheat and cutting oxygen orifice configuration required for stable acetylene combustion.

Technically, this tip is a Size 1 nozzle, which typically indicates a cutting capacity range suitable for mild steel plate thicknesses from approximately 1/2 inch to 1 inch (12mm to 25mm). The internal geometry features a smooth bore cutting oxygen channel to maintain stream coherence over the cut distance, minimizing kerf width and slag accumulation. The preheat ports are machined to ensure uniform flame distribution, essential for rapid starts and maintaining the ignition temperature of the base metal during the cut.

Construction-wise, the CS62901 utilizes a heavy-duty copper alloy shell. Copper is selected for its high thermal conductivity, which is critical for withdrawing heat from the tip face to prevent overheating and potential flashbacks. The seating area is machined to tight tolerances to ensure a positive metal-to-metal seal within the torch head, preventing dangerous gas leaks or mixing within the torch body. This tip is fully compatible with Harris-style torches such as the Model 62, Model 73, and compatible attachments.
