0333-0208 - Victor Size 6 BTN Propane Cutting Tip

Technical Overview of the Victor 6-BTN Cutting Tip

The Victor 0333-0208 6-BTN Cutting Tip is a specialized Series 1 consumable engineered for heavy industrial cutting applications utilizing alternate fuel gases such as Propane and Natural Gas. As a Size 6 tip, it is calibrated to process mild steel and low-alloy structural steels ranging from 5 inches to 6 inches (127mm to 152mm) in thickness. This specific model belongs to the BTN series, which is distinguished by its heavy preheat characteristics. The "Heavy Preheat" designation indicates a design optimized to deliver a higher volume of BTU output during the preheat cycle, which is critical when utilizing fuel gases that have a lower flame temperature and heat transfer rate compared to Acetylene. This makes the 6-BTN particularly effective for bevel cutting operations where the flame is deflected, or when cutting materials with surface contaminants such as rust, scale, or primer.

Structurally, the 6-BTN utilizes a two-piece design common to high-performance alternate fuel tips. The assembly consists of an outer copper shell and a brass inner member with splined gas passages. This configuration allows for easy cleaning and maintenance, as the components can be separated to clear slag or carbon buildup. The tip is rated for cutting High-Strength Low-Alloy (HSLA) steels, T1 structural steel, and HY-80 naval armor plate, demonstrating its capability in demanding fabrication and demolition environments. Operational parameters are specific: the tip requires a cutting oxygen pressure range of 65 to 85 PSIG and a preheat oxygen pressure of 30 to 35 PSIG. Fuel gas pressure should be maintained between 8 and 15 PSIG to ensure a stable flame and prevent starvation or flashback.

The gas mixing technology within the Victor torch and tip assembly ensures a safe and efficient burn. The separation of the preheat gases until they reach the tip face (in the case of nozzle-mix designs) or the injector (in the case of injector torches) is complemented by the BTN's specific geometry which stabilizes the flame front even at the high flow rates required for cutting 6-inch steel. Industrial MRO professionals should note that this tip is designed for Series 1 torches and is not compatible with Series 3 or other proprietary torch head designs without appropriate adapters.
