SC46-2 - Smith SC46-2 Heavy Duty Propane Cutting Tip, Size 2

Smith SC46-2 Rugged Duty Cutting Tip: Engineered for Extreme Environments

The Smith SC46-2 Rugged Duty Cutting Tip is a specialized consumable designed to meet the rigorous demands of heavy industrial cutting, scrapping, and demolition. Unlike standard general-purpose tips, the SC46 series is engineered with a robust one-piece construction that significantly enhances durability and heat resistance. This specific model, a Size 2 tip, offers a cutting capacity of approximately 1-1/4 inches (32mm), making it a versatile choice for processing structural steel, pipe, and heavy scrap materials. It is calibrated specifically for use with alternate fuel gases, including Propane and Natural Gas, which require different preheat port configurations compared to acetylene to maintain a stable and effective cutting flame.

One of the defining technical characteristics of the SC46-2 is its ability to perform in conditions where excessive reflected heat is present. In scrapping operations, operators often cut into cavities, corners, or against heavy plates where heat is deflected back toward the torch. Standard tips can overheat, leading to flashbacks or premature failure. The SC46-2's heavy-duty design mitigates this risk, ensuring consistent performance even when the tip is subjected to high thermal loads. Furthermore, the tip is optimized for cutting dirty, rusty, or heavily coated metals. The flame characteristics are tuned to burn through surface contaminants like paint and rust without losing the preheat cone, ensuring a continuous cut without frequent interruptions for cleaning.

Compatibility is a key factor for industrial procurement. The SC46-2 is designed to fit seamlessly with Smith Equipment's ecosystem of heavy-duty torches. It is directly compatible with DG200 and SC200 Series Cutting Attachments, as well as all Smith SC and DG Series Hand Torches and Machine Cutting Torches. This broad compatibility ensures that facilities utilizing Smith apparatus can standardize on the SC46 series for their propane and natural gas cutting needs. The tip features precision-drilled preheat holes and a smooth cutting oxygen bore, which promotes a laminar oxygen stream for clean, straight cuts with minimal slag accumulation, reducing post-cut grinding and preparation time.

In summary, the Smith SC46-2 represents a convergence of durability and precision. It allows industrial operators to leverage the cost-effectiveness of propane and natural gas without sacrificing cutting speed or quality. Whether utilized in a scrapyard, a construction site, or a fabrication shop dealing with reclaimed materials, this tip delivers reliable ignition, stable preheat, and a powerful cutting stream capable of severing 1-1/4 inch steel with efficiency.
