Smith SC40 Series Size 4 Propane Cutting Tip

Smith SC40-4 Cutting Tip for Propane and Natural Gas

Upgrade your cutting game with the Smith SC40-4, a heavy-duty cutting tip designed to help you get the most out of your propane or natural gas setup. If you are running Smith SC or DG series torches, this is the genuine replacement part you need to tackle thicker materials with confidence. The Size 4 orifice is calibrated to cut through steel up to 3 inches thick, making it a versatile choice for everything from demolition work to heavy fabrication projects.

Why choose the SC40-4? It features a smart two-piece design that is optimized for alternative fuels. Propane and natural gas burn differently than acetylene, and this tip is built to handle those specific flow rates and heat characteristics. The medium preheat capability ensures you get a quick start and a stable flame, so you aren't wasting time waiting for the metal to reach ignition temperature. Plus, the two-piece construction saves you money in the long run—if the outer shell gets damaged or dirty, you can take it apart for easy cleaning or replacement, extending the overall life of the tip.

Welders Supply provides high-quality consumables that keep your shop running smoothly. The Smith SC40-4 delivers clean, smooth cuts that reduce the need for secondary grinding or machining. Whether you are using a hand torch or a machine cutting assembly, this tip snaps right in and provides the tight seal and reliable arc of fire you expect from Smith Equipment products. Don't let worn-out tips slow down your production; stock up on the SC40-4 and keep your cuts clean and your downtime low.
