The Smith MC40-2 is a premium Size 2 cutting tip engineered specifically for use with propane and natural gas. Designed to meet the rigorous demands of industrial metalworking, this tip offers a cutting capacity of up to 1-1/4 inches (32 mm), making it an essential consumable for fabrication shops, scrap yards, and maintenance departments utilizing Smith Equipment medium-duty torches. As part of the renowned MC40 series, this tip exemplifies the quality and reliability that professionals expect from the Smith brand.
Unlike standard acetylene tips, the MC40-2 utilizes a two-piece construction optimized for alternate fuels. This design features an outer shell and an inner member, which allows for the distinct preheat flame characteristics required by propane. The separation of the two parts also facilitates easier cleaning and maintenance. If the splines become clogged with carbon or slag, the tip can be disassembled and cleaned from the back, extending the service life of the consumable and ensuring consistent flame quality over time.
Safety is paramount in oxy-fuel cutting, and the MC40-2 incorporates Smith's signature in-tip gas mixing technology. By mixing the oxygen and fuel gas within the tip rather than the torch head or tube, the volume of mixed gas is kept to an absolute minimum. This design drastically reduces the potential for flashback and sustained backfire, protecting both the operator and the expensive torch equipment. Additionally, the tip features a concave end which helps to recess the flame, further resisting flameout when the tip accidentally touches the workpiece.
The MC40-2 is designed with a fully swaged, smooth bore that promotes laminar gas flow. This results in a stable, high-velocity cutting oxygen stream that produces clean, narrow kerfs with minimal slag accumulation. The medium preheat setting is perfectly balanced to bring steel to ignition temperature quickly without overheating the top edge, ensuring high-quality cuts on plates, pipes, and structural beams. Compatible with a wide range of Smith attachments including the DG109A, MC505, MC509, CC509P, and AC309, this tip is a versatile addition to any welder's toolkit.
