0333-0328 - Victor Size 6 HPN Propane & Natural Gas Cutting Tip

Technical Overview of the Victor 6-HPN Cutting Tip

The Victor 0333-0328 6-HPN Cutting Tip is a high-performance consumable engineered for heavy industrial cutting applications utilizing alternative fuels such as Propane and Natural Gas. As a Size 6 tip within the HPN series, it is calibrated to deliver a substantial preheat flame and a powerful cutting oxygen stream capable of severing carbon steel up to 8 inches (203mm) in thickness. This capability makes it an essential component for heavy fabrication, scrap yards, and structural steel dismantling where deep penetration and consistent flame stability are paramount.

Structurally, the 6-HPN utilizes a two-piece design, characteristic of high-efficiency alternative fuel tips. The assembly consists of a brass inner member with splined gas passages and a copper outer shell. This configuration allows the slower-burning propane gas to mix properly with the preheat oxygen at the tip face, creating a stable, high-temperature envelope necessary to bring heavy plate to kindling temperature rapidly. The recess created by the outer shell also serves to protect the splines from damage and slag adhesion, extending the service life of the consumable under harsh working conditions.

Operational parameters for the 0333-0328 are specific to its size and fuel type. It requires a cutting oxygen pressure range of 55 to 65 PSIG to maintain the kinetic energy of the oxygen jet through the 8-inch kerf. Fuel gas pressure should be maintained between 8 and 12 PSIG to ensure adequate volume for the heavy preheat flame. This tip is a Type 1 configuration, making it compatible with standard Victor heavy-duty hand torches and cutting attachments (typically the 300 series handles and compatible equipment). Operators must ensure their regulator delivery capacity matches these flow requirements to prevent starvation during the cut.
