Smith SC40-1 Heavy-Duty Propane/Natural Gas Cutting Tip Size 1

Miller Smith SC40-1 Propane Cutting Tip - Size 1

Upgrade your cutting setup with the Miller Smith SC40-1, a Size 1 cutting tip optimized for propane and natural gas applications. Designed to cut steel up to 5/8 inch (16 mm) thick, this heavy-duty tip is a versatile addition to any welder's arsenal, compatible with all Smith SC and DG Series hand torches as well as select machine torches. The SC40-1 stands out with its two-piece construction, which separates the preheat and cutting oxygen channels to maximize efficiency with slower-burning alternative fuels like propane. This ensures you get a clean, consistent cut without the high cost of acetylene.

One of the most convenient features of this Smith tip is the "Slip-In" design. Forget about hunting for a wrench to change your tip; simply insert the tip and tighten the nut by hand. The tip rotates freely until the nut is tightened, allowing you to orient the preheat flames exactly where you need them before locking it down. This positive seal is not only easy to achieve but also exceptionally safe. The soft seats are recessed into the tip nut, protecting them from drops and rough handling that often occur in busy shops or on job sites. This thoughtful design significantly extends the life of the tip compared to traditional metal-to-metal cone seats.

Safety is paramount with Miller Smith equipment. The SC40-1 features the legendary "Dual Guard" in-tip mixing system. By mixing the preheat gases in the tip rather than the torch handle, the risk of flashback is isolated to the disposable tip, protecting both the expensive torch and the operator. Additionally, the concave face of the tip helps prevent the flame from extinguishing if the tip touches the metal, and the smooth, swaged interior ensures excellent gas flow for quick starts and less slag adhesion. For welders seeking reliability, safety, and ease of use with propane or natural gas, the SC40-1 is the industry standard.
