LG-4 - Size 4 Propane & Natural Gas Cutting Tip - 2 Piece Design

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.
