SC12-000 - Smith Style SC12 Size 000 Heavy Duty Acetylene Tip

Technical Overview of the Smith Style SC12-000

The Smith Style SC12-000 is a precision-engineered aftermarket cutting tip designed to replicate the performance specifications of the OEM Smith SC12 series. This specific model is a Size 000 tip, calibrated for low-range cutting applications where precision on thinner materials is paramount. It is strictly compatible with Oxygen and Acetylene gas mixtures, utilizing the specific combustion properties of acetylene to provide a focused, high-temperature preheat flame suitable for rapid piercing and clean severance of mild steel.

Structurally, the tip features a heavy-duty design compatible with Smith's industrial torch handles and cutting attachments. The internal geometry is machined to ensure laminar gas flow, reducing turbulence and promoting a stable preheat cone. The seating mechanism employs a double-seat design, a critical safety and performance feature that ensures a gas-tight seal against the torch head, preventing flashbacks and leaks. The tip is constructed from high-grade copper alloy, which provides excellent thermal conductivity to dissipate heat away from the orifice face, thereby extending the service life of the tip during prolonged cutting operations.

This Size 000 unit is rated for cutting material thicknesses up to approximately 1/8 inch (3mm). It is essential for operators to match the tip size to the material thickness to maintain optimal oxygen velocity and minimize kerf width. Using a tip that is too large for thin material can result in excessive slag, warped metal, and wasted gas, while the SC12-000 is specifically tuned to deliver the correct BTU output and oxygen stream velocity for light-gauge fabrication and HVAC applications.

In industrial MRO contexts, this tip serves as a reliable consumable for maintenance teams utilizing Smith equipment. It supports standard heavy-duty cutting attachments and is interchangeable with standard SC12 series tips, allowing for seamless integration into existing tool cribs without the need for adapter hardware.
