SC60-1 - Smith SC60 Series Size 1 Heavy-Duty Propylene Cutting Tip

Precision Propylene Cutting with Smith SC60-1

The Smith SC60-1 Cutting Tip is a specialized heavy-duty consumable engineered specifically for use with propylene and propylene-based fuel gases. Designed to meet the rigorous demands of industrial metal fabrication and scrapping, this Size 1 tip provides a cutting capacity of approximately 1/2 inch to 5/8 inch (13mm to 16mm). Unlike standard acetylene tips, the SC60 series utilizes a two-piece construction consisting of a brass inner member and a copper outer shell. This design is critical for alternative fuels like propylene, as it allows for the proper recessed flame seating required to stabilize the burn and maximize thermal transfer into the workpiece.

Safety and efficiency are paramount in the engineering of the SC60-1. The tip features in-tip gas mixing, a technology that combines preheat oxygen and fuel gas within the tip itself rather than in the torch head. This significantly reduces the volume of mixed gas in the system, thereby adding a substantial layer of resistance against flashbacks. Furthermore, the tip face is designed with a concave geometry. This recessed end helps protect the orifices from damage if the torch accidentally touches the plate, and it also aids in reducing backfire and resisting flameout during aggressive cutting operations.

Operational specifications for the SC60-1 are tuned for optimal economy and performance. It requires a cutting oxygen flow rate of 75 - 85 SCFH, a preheat oxygen flow of 38 SCFH, and a propylene flow of 9 SCFH. The fully swaged smooth bore ensures a laminar gas flow, which translates to faster starts and cleaner cuts with minimal slag accumulation. This tip is compatible with a wide range of Smith equipment, including SC200 and DG200 series attachments, as well as all Smith SC and DG series hand torches and 3-hose machine torches.
