SC60-4 - Smith SC60-4 Propylene Cutting Tip Size 4

Technical Overview of the Smith SC60-4 Cutting Tip

The Smith Equipment SC60-4 is a specialized heavy-duty cutting tip engineered for optimal performance with propylene and propylene-based fuel gases. As part of the SC60 series, this consumable features a two-piece construction with a medium preheat capacity, making it suitable for a wide range of industrial cutting applications. The tip is designated as Size 4, which typically correlates to a cutting capacity of approximately 3 inches (76 mm) of steel, providing robust penetration and clean kerf lines for structural fabrication and demolition tasks.

Technically, the SC60-4 distinguishes itself with Smith's proprietary in-tip gas mixing technology. Unlike universal mixers located in the torch head, this tip acts as a precision-engineered mixer where preheat oxygen and fuel gas combine. This design significantly enhances safety by keeping the mixed gas volume to a minimum, thereby isolating potential sustained backfires within the tip itself rather than the torch handle. The tip's geometry includes a concave end which serves a dual purpose: it protects the seating surface from physical damage during handling and helps resist flameout during operation.

The internal bore of the SC60-4 is fully swaged, a manufacturing process that results in an exceptionally smooth gas path. This laminar flow characteristic is critical for maintaining a stable flame and ensuring fast starts. Furthermore, the smooth surface minimizes the adhesion of molten slag, allowing for cleaner cuts and easier maintenance. This tip is designed for compatibility with a broad ecosystem of Smith equipment, including DG200 and SC200 series cutting attachments (up to size SC60-5), all Smith SC and DG series hand torches, and specific machine cutting torches.
