Smith MC40-2 Medium Duty Propane Cutting Tip Size 2

Miller Smith MC40-2 Cutting Tip: Superior Performance with Propane

Upgrade your cutting setup with the Miller Smith MC40-2, a Size 2 cutting tip designed to deliver exceptional results when using propane or natural gas. Capable of slicing through steel up to 1-1/4 inches thick, this tip is the ideal choice for welders and fabricators who prefer the economy and availability of alternate fuels without sacrificing cut quality. Built to the exacting standards of Miller Smith, the MC40-2 ensures that your medium-duty torch performs at its peak, delivering fast starts and smooth finishes on every job.

Rugged Design for Industrial Use

The MC40-2 features a heavy-duty two-piece design that stands up to the harsh environment of the workshop. The outer shell is crafted from durable copper to withstand high heat reflection, while the inner brass member is precision-machined to ensure perfect gas flow alignment. One of the standout features of this tip is its concave face. This recessed geometry protects the critical orifice edges from nicking if the tip is dropped or bumped against the work surface. A smooth, undamaged face is crucial for maintaining a symmetrical flame and a straight cutting stream.

Optimized for Clean Cuts

Achieving a clean cut with propane requires a tip designed to handle the specific combustion properties of the gas. The MC40-2 features a medium preheat pattern that provides sufficient heat energy to pierce and cut efficiently, even on dirty or rusty plate, without the excessive preheat that can cause top-edge melting. The fully swaged interior minimizes turbulence in the oxygen stream, resulting in a coherent jet that blows slag away cleanly. This means less time spent grinding and cleaning up parts after the cut, improving overall shop productivity.

Seamless Compatibility

This tip is engineered to fit perfectly with Smith's line of medium-duty cutting attachments and combination torches. It seats securely into models such as the DG109A, MC509, and AC309, ensuring a leak-free connection. The "Soft Seat" design often associated with Smith tips helps prevent damage to the torch head seating surface, prolonging the life of your torch handle. Whether you are working on HVAC installations, automotive repair, or general metal fabrication, the MC40-2 provides the reliability and precision you need to get the job done right.
