Industrial SC46-2 Cutting Tip

Smith SC46-2 Propane/Natural Gas Cutting Tip — One-Piece Heavy-Duty Preheat, Size 2. This rugged Smith-style cutting tip is designed for oxy-fuel cutting on Smith/Miller torches and is compatible with either propane or natural gas as the fuel gas, paired with cutting oxygen for the actual cut. It can reliably cut through steel up to 1-1/4 inches (32 mm) thick when using the proper oxygen supply and fuel gas flow. Operational requirements for the SC46-2 include 105–135 SCFH of cutting oxygen, with a preheat oxygen flow of 56 SCFH and a preheat fuel flow of 8 SCFH, reflecting its role as a heavy-preheat, high-durability tip in demanding cutting jobs. The one-piece construction emphasizes durability for rugged hand or machine cutting, and the SC46-2 designation identifies the size 2 orifice within the SC46 family. Common applications span fabrication, maintenance, and structural work where rusted, painted, or heavily scaled steel must be cut efficiently and with consistent preheat performance.
