MC12-1 - Smith MC12 Series Size 1 Acetylene Cutting Tip

Precision Medium-Duty Acetylene Cutting Tip

The Smith MC12-1 is a high-performance cutting tip engineered for medium-duty industrial applications. Designed to operate exclusively with acetylene gas, this Size 1 tip provides a cutting capacity of approximately 1/2 to 5/8 inch (13mm to 16mm), making it an essential consumable for fabrication shops, maintenance departments, and automotive repair facilities. The tip belongs to the renowned MC12 Series, known for its reliability and precision in oxy-fuel processes.

Constructed from high-quality copper, the MC12-1 features a fully swaged design. This manufacturing process creates ultra-smooth internal gas passages that minimize turbulence and promote laminar flow. The result is a stable, focused preheat flame and a powerful cutting oxygen stream that produces clean, high-quality cuts with minimal slag adhesion. The one-piece construction also ensures efficient heat transfer, keeping the tip cooler during prolonged operation.

Advanced Safety and Design

Safety is paramount in the design of the MC12-1. It utilizes Smith's signature "in-tip" mixing technology, where oxygen and acetylene are mixed within the tip itself rather than in the torch head or tube. This significantly reduces the volume of potentially explosive mixed gas stored in the system, thereby lowering the risk of flashback and enhancing operator safety. Additionally, the tip features a slip-in connection style that allows for quick, tool-free installation. The connection is hand-tightened to form a perfect, positive seal, while the recessed seats are shielded from the intense heat of the cutting zone, preventing deformation and extending the service life of the component.
