Smith SC50-4 Heavy Duty Propane/Natural Gas Cutting Tip, Size 4

Miller Smith SC50-4 Propane Cutting Tip - Size 4

Maximize your cutting efficiency and reduce fuel costs with the authentic Miller Smith SC50-4 Cutting Tip. Designed for the professional welder and fabricator, this size 4 tip is optimized for Propane and Natural Gas, offering a cost-effective alternative to acetylene without sacrificing performance on heavy steel. Capable of cutting material up to 3 inches thick, the SC50-4 is a staple for workshops that require reliable, heavy-duty cutting power. The two-piece design separates the preheat and cutting oxygen paths effectively, allowing for the specific combustion requirements of alternate fuels.

The SC50-4 is built to withstand the harsh environments of heavy industry. It features a "Heavy Preheat" configuration, which is essential when working with propane. Propane burns at a lower temperature than acetylene in the primary flame, so the heavy preheat ensures the steel reaches ignition temperature quickly, even on thick plate or dirty surfaces. This tip excels in applications involving demolition, scrapping, and heavy equipment repair where rust and scale are common. The fully swaged smooth tip bore ensures that the cutting oxygen stream remains tight and coherent, delivering precise cuts with minimal kerf and slag.

Smith Equipment has integrated several longevity features into this series. The tip seat is protected by a removable insert (on the back end) and the face is concave to resist damage from spatter and accidental contact. This shape also helps isolate sustained backfires, protecting both the operator and the torch handle. Whether you are using a hand torch like the Smith SC200 or a machine torch, the SC50-4 delivers consistent, high-quality results. Please note: When using liquid oxygen systems, ensure your manifold can supply sufficient gas volume for these heavy-flow tips.
