0330-0504 - Victor Size 6 HDN Propane/Natural Gas Cutting Tip

Technical Overview of the Victor 0330-0504 6-HDN Cutting Tip

The Victor 0330-0504 6-HDN Cutting Tip is a specialized consumable engineered for heavy-duty industrial cutting applications utilizing alternative fuel gases, specifically Natural Gas and Propane. As part of the HDN series, this tip is designed to withstand the rigorous thermal demands of prolonged cutting operations on thick ferrous metals. The '6' designation indicates a large orifice size, typically rated for severing steel sections ranging from 6 to 8 inches in thickness, making it an essential component for structural demolition, heavy fabrication, and scrap processing facilities.

Structurally, the 6-HDN features a two-piece design, a standard configuration for propane and natural gas tips. This architecture consists of a brass inner member with splined gas passages and a copper outer shell. This separation allows the preheat gas to be recessed, protecting the tip face from the intense reflected heat associated with heavy plate cutting. The splined inner piece creates a heavy preheat flame pattern required to bring the base metal to ignition temperature when using fuels with lower flame temperatures than acetylene. The outer shell is often chrome-plated to resist the adhesion of molten slag and spatter, thereby extending the service life of the consumable.

Compatibility is a key feature of the 0330-0504. It is manufactured to fit industry-standard Victor 300 Series torch handles and cutting attachments, ensuring seamless integration into existing heavy-duty oxy-fuel setups. Users must ensure their gas regulation equipment is capable of delivering the requisite flow rates and pressures demanded by a size 6 tip to maintain a stable neutral flame and efficient cutting oxygen stream. Proper seating of the tip within the torch head is critical to prevent backfires and ensure optimal gas mixing.
