SC40-1 - Smith SC40-1 Heavy-Duty Propane/Natural Gas Cutting Tip Size 1

Smith Equipment SC40-1 Heavy-Duty Propane & Natural Gas Cutting Tip

The Smith Equipment SC40-1 is a premium heavy-duty cutting tip designed specifically for use with propane, natural gas, and propylene based fuel gases. Engineered for professional industrial environments, this Size 1 tip delivers precise cutting capabilities for steel thicknesses up to 5/8 inch (16 mm). As part of the renowned SC Series, it represents the pinnacle of oxy-fuel safety and performance, utilizing Smith's signature in-tip mixing technology. This advanced design ensures that fuel and oxygen are mixed only within the tip itself, rather than in the torch head or tubes, significantly reducing the volume of mixed gas and thereby minimizing the potential energy of a flashback. This feature is critical for maintaining operator safety during heavy-duty cutting operations.

Constructed as a two-piece assembly, the SC40-1 features a medium preheat capacity, making it ideal for general hand and machine cutting where consistent heat distribution is required. The tip utilizes a "slip-in" connection mechanism, a hallmark of Smith's user-centric engineering. This design allows operators to install and remove tips by hand without the need for wrenches, ensuring a perfect, positive seal every time while reducing setup time. Furthermore, the tip seats are recessed and protected to prevent damage such as nicking or scratching during handling, which extends the service life of the consumable and maintains a leak-proof connection with the torch head.

Durability and cut quality are further enhanced by the tip's physical geometry. The concave-shaped tip end is specifically designed to protect the orifices from damage and to help reduce backfire and resist flameout, even when the tip is accidentally touched to the workpiece. The internal bore is fully swaged and smooth, promoting laminar gas flow for fast starts and minimizing slag build-up, which reduces downtime for cleaning. Whether used with SC or DG series hand torches or compatible machine cutting assemblies, the SC40-1 delivers reliable, high-quality cuts with alternative fuel gases.
