Smith Equipment Heavy Duty Propane Cutting Tip Size 4

Rugged Duty Cutting with the Smith SC46-4

For welders and fabricators facing the toughest cutting conditions, the Smith SC46-4 Heavy Duty Cutting Tip is the ultimate solution. When your work involves more than just clean plate—think scrap yards, demolition zones, and maintenance on heavily weathered equipment—standard cutting tips often struggle to maintain a flame or clog instantly. The SC46-4 is built differently. It is a "Rugged Duty" one-piece tip designed specifically to handle the abuse of cutting dirty, painted, and rusted steel without missing a beat.

This size 4 tip offers a powerful cutting range, capable of severing steel up to 4 inches (102mm) thick. It is calibrated for use with Propane and Natural Gas, fuels that are ideal for heavy cutting due to their high total heat output and cost savings compared to acetylene. The heavy-duty construction of the SC46-4 helps it resist the intense reflected heat that occurs when cutting into deep crevices or during heavy gouging and scrapping tasks. This durability means you spend less time changing burnt-out tips and more time working.

The Smith SC46-4 is designed for broad compatibility within the Smith Equipment ecosystem. It fits perfectly on DG200 and SC200 series cutting attachments, as well as all Smith SC DG series hand torches and machine torches. This makes it a versatile addition to any torch kit, ready to tackle thick sections and less-than-perfect base metals at a moment's notice. The one-piece design simplifies maintenance and ensures a robust gas path for consistent flame characteristics, even in windy outdoor conditions.

Choosing the right tip for the fuel gas and application is critical for cut quality. By pairing the SC46-4 with your propane supply, you leverage a tool designed to maximize the specific combustion properties of alternate fuels. The result is a forceful preheat and a clean oxygen stream that blows through heavy rust and scale. If your daily grind involves tearing down old structures or processing heavy scrap, the Smith SC46-4 is the reliable, high-performance partner your torch needs.
