OVERVIEW

Heavy-Duty Propane & Natural Gas Cutting Performance

The Smith SC50-7 Cutting Tip is a premium industrial consumable designed for extreme cutting applications using alternate fuel gases. Engineered by Smith Equipment (Miller), this Size 7 tip represents the upper echelon of the SC50 series, capable of slicing through carbon steel up to 14 inches (354mm) thick. Unlike standard acetylene tips, the SC50-7 utilizes a specialized two-piece construction with a heavy preheat shell. This design is critical for Propane and Natural Gas, which have lower flame propagation rates than acetylene; the heavy preheat feature ensures the base metal reaches ignition temperature rapidly, even on massive plates and castings.

Precision Engineering for Thick Plate

The SC50-7 is built with a removable outer shell and a precision-machined inner insert. This two-piece configuration not only optimizes the gas mixing for a high-intensity preheat flame but also simplifies maintenance. If the tip becomes clogged with slag or spatter during heavy piercing operations, the outer shell can be removed to easily clean the splines of the inner member. The tip is manufactured from high-quality copper alloy to withstand the intense reflected heat generated when cutting 14-inch steel, ensuring longevity and consistent performance in harsh environments like scrap yards and foundries.

Compatibility and Safety

Safety and equipment matching are paramount when using high-flow tips. The SC50-7 is designed for use with Smith SC and DG Series Hand Torches and Smith 3-Hose Machine Cutting Torches. Please note that due to the high gas volume requirements for a Size 7 tip, it is NOT compatible with smaller attachments like the DG200 or SC200 (which max out at size 5), nor standard 2-hose machine torches (max size 6). Users must ensure their gas supply system—regulators, hoses, and cylinders—can supply the necessary volume to prevent starvation and backfires. When using liquid oxygen, manifolding may be required.

FAQ

The SC50-7 is designed for use with Propane or Natural Gas. It is not suitable for Acetylene.

The Smith SC50-7 Size 7 tip is rated to cut steel up to 14 inches (354mm) thick.

No, the SC50-7 is too large for the DG200 or SC200 attachments. Those attachments have a maximum tip size limit of SC50-5.

This is a two-piece cutting tip, featuring a separate inner member and outer shell, which is standard for high-performance propane tips.

Yes, but only on Smith 3-Hose Machine Cutting Torches. It exceeds the capacity of standard 2-hose machine torches (which max out at size 6).

Because it is a two-piece tip, you can separate the outer shell from the inner insert to easily clean the splines and gas passages.

Propane and Natural Gas burn at a lower temperature than Acetylene. The heavy preheat design provides more flame volume to bring thick steel to ignition temperature quickly.

This is a genuine Smith Equipment product (now under the Miller Electric family of brands).
