MC12-00 - Smith MC12 Series Size 00 Acetylene Tip

Precision Engineered Medium-Duty Acetylene Tip

The Smith MC12-00 Cutting Tip represents the pinnacle of medium-duty oxy-acetylene cutting technology, designed specifically for professionals who demand precision and safety. As part of the renowned MC12 Series, this Size 00 tip is engineered to deliver clean, consistent cuts on steel thicknesses ranging from 1/8 inch up to 3/16 inch (5 mm). The core of its performance lies in the manufacturing process; each tip is fully swaged from high-quality copper. This swaging process creates mirror-smooth internal gas passages that minimize turbulence, allowing for a stable preheat flame and a coherent cutting oxygen stream. The result is reduced slag accumulation and faster cutting speeds compared to drilled tips.

Safety is paramount in the design of the MC12-00. It features Smith's signature "In-Tip" gas mixing technology. Unlike tube-mix torches where gases combine in the handle or attachment, this tip mixes the oxygen and acetylene within the tip itself. This design significantly improves safety by keeping the volume of mixed gas to an absolute minimum, thereby isolating sustained backfires in the tip and protecting the operator and the torch equipment. Furthermore, the tip face is concave, a geometric choice that helps reduce backfire tendency and resists flameout when the tip is brought close to the workpiece.

Operational efficiency is enhanced by the unique "Slip-In" design. The MC12-00 does not require a wrench for installation; it simply slides into the torch head and is tightened by hand with the retaining nut. This ensures a perfect, positive seal every time and prevents overtightening which can damage torch heads. The seating area is recessed and protected, shielding the critical sealing surfaces from nicks and damage during handling or storage. This attention to detail ensures a long service life and reliable performance in industrial environments.

This tip is compatible with a wide range of Smith medium-duty cutting attachments, including the DG109A, MC505, MC509, CC509P, and AC309. It is an essential consumable for fabrication shops, maintenance departments, and HVAC professionals utilizing Smith's medium-duty oxy-fuel systems.
