SC60-5 - Smith SC60-5 Heavy-Duty Propylene Cutting Tip Size 5

Technical Overview of the Smith SC60-5 Propylene Cutting Tip

The Smith SC60-5 is a specialized heavy-duty cutting tip engineered for industrial applications utilizing propylene or propylene-based fuel gases. As part of the SC60 series, this Size 5 tip is designed to handle substantial material thicknesses, offering a cutting range of approximately 6 to 8 inches (152 mm to 203 mm). The tip features a two-piece construction, which is essential for alternate fuels like propylene to ensure a stable flame and efficient combustion compared to single-piece acetylene tips.

A defining technical characteristic of this Smith Equipment product is the In-Tip Gas Mixing technology. Unlike traditional designs that mix gases in the torch head or tubes, the SC60-5 combines the preheat oxygen and fuel gas within the tip itself. This precision-engineered mixing chamber optimizes the fuel-to-oxygen ratio for maximum thermal efficiency while significantly adding resistance to flashback. By isolating the mixed gas volume to the tip, the potential for sustained backfire into the torch handle is drastically reduced, enhancing operator safety.

The physical geometry of the tip is designed for longevity and performance. It incorporates a concave-shaped tip end, which serves a dual purpose: it helps reduce backfire and resists flameout, while also recessing the orifice to protect the tip seat from nicking if it accidentally contacts the workpiece. Furthermore, the exterior is fully swaged and smooth. This manufacturing process minimizes surface irregularities where molten slag could adhere, facilitating easier cleaning and promoting faster, cleaner cut starts. The SC60-5 is rated for medium preheat, making it versatile for general purpose heavy cutting where rapid preheating of thick plate is required.

Compatibility: This tip is designed for use with Smith's heavy-duty equipment ecosystem, including DG200 and SC200 Series Cutting Attachments (max size SC60-5), all Smith SC DG Series Hand Torches, Smith 2-Hose Cutting Torches (max size SC60-6), and all Smith 3-Hose Machine Cutting Torches.
