Smith SC12-2 Acetylene Cutting Tip: Precision Engineering for Safety

The Smith SC12-2 is a premium Size 2 cutting tip designed for heavy-duty industrial applications using acetylene gas. Engineered by Smith Equipment (a division of Miller Electric), this tip represents the gold standard in oxy-fuel cutting technology. It is capable of cleanly cutting steel ranging from 3/4-inch to 1-1/4 inches (32mm) in thickness, making it a versatile choice for fabrication shops, structural steel work, and maintenance operations.

One of the standout features of the SC12 series is the In-Tip Gas Mixing technology. Unlike standard tips that rely on mixing chambers within the torch handle, the SC12-2 mixes the preheat oxygen and acetylene inside the tip itself. This design drastically improves safety by keeping the combustible gas mixture volume to a minimum and isolating it from the torch body. In the event of a sustained backfire, the reaction is contained within the replaceable tip, protecting both the operator and the expensive torch equipment.

The tip is constructed from high-quality copper, swaged to ensure mirror-smooth internal gas passages. This manufacturing process reduces turbulence in the gas flow, resulting in a stable, high-temperature preheat flame and a coherent cutting oxygen stream. The result is a cleaner cut face with minimal slag accumulation, reducing post-cut grinding time. The tip also features a concave end which protects the orifice seating from damage if the torch is accidentally bumped against the workpiece.

Designed for efficiency, the SC12-2 requires a cutting oxygen flow rate of 105-135 SCFH and a preheat acetylene flow of 10.5 SCFH. It is fully compatible with Smith's DG200 and SC200 series cutting attachments, as well as all SC and DG series hand and machine torches.
