OVERVIEW

Optimized Performance for Alternative Fuels

The LG-4 Multi-Tip is a specialized cutting consumable designed explicitly for use with Propane and Natural Gas. Unlike standard acetylene tips, this unit utilizes a two-piece construction consisting of a brass inner member with splines and a copper outer shell. This design is critical for alternative fuels, as it creates a recess that anchors the flame, preventing it from blowing out due to the lower burning velocity of propane compared to acetylene. The Size #4 orifice is engineered for heavy-duty applications, capable of severing thick sections of carbon steel with precision and speed.

Heavy-Duty Cutting Capacity

With its #4 size classification, this tip is intended for substantial fabrication and demolition work. It provides a robust preheat flame necessary to quickly bring heavy plate or structural beams to their ignition temperature. The separation of the inner and outer parts allows for thorough maintenance; operators can easily remove the outer shell to clean the gas splines, ensuring consistent gas flow and flame symmetry over the lifespan of the product. This feature significantly extends the usability of the tip in harsh industrial environments where carbon buildup and spatter are common.

Durability and Precision

Manufactured to high tolerances, the LG-4 ensures a tight, leak-free seal within the torch head, maintaining safety and efficiency. The copper outer shell offers excellent heat dissipation, reducing the risk of overheating during prolonged cuts. Whether used in scrap yards, structural steel erection, or general heavy fabrication, this tip delivers the reliability professionals demand when switching from acetylene to more economical fuel gases like propane or natural gas.

FAQ

No, this is a 2-piece tip designed specifically for Propane or Natural Gas. Using it with Acetylene can cause dangerous overheating and backfires.

2-piece tips are required for alternative fuels like propane because they create a recess at the tip end. This anchors the flame, which would otherwise blow off due to the lower flame propagation speed of propane compared to acetylene.

You can separate the outer copper shell from the inner brass insert. This allows you to wipe down the splines and remove carbon buildup easily without damaging the orifice.

While exact ratings vary by torch brand, a Size #4 tip is generally rated for heavy cutting, typically handling steel thicknesses between 2 to 4 inches (approx. 50-100mm).

No, cutting tips are specific to the torch head style (e.g., Victor, Harris, Airco). Please verify your torch's series compatibility before purchasing.

If the flame is blowing off, ensure you are using the correct fuel pressure settings for a Size #4 tip. Also, check that the outer shell is fully seated and the tip is clean.

This is a standard cutting tip. While it can remove material, specific gouging tips are better suited for removing welds or creating grooves.
