MC-125 - Smith MC12-5 Medium Duty Acetylene Cutting Tip, Size 5

Reliable Cutting for the Professional Welder

When you are out in the field or busy in the shop, you need consumables that work as hard as you do. The Smith MC12-5 Acetylene Cutting Tip is the go-to choice for welders using Smith medium-duty torches who need to cut thick steel. With a massive cutting capacity of up to 6 inches, this Size 5 tip allows you to tackle heavy structural beams, thick plate, and demolition work without needing to switch to a heavy-duty torch. It is built to be a workhorse, delivering consistent preheat flames and a powerful cutting jet that blows through metal cleanly, saving you time on grinding and cleanup later.

One of the best features of the Smith MC12 series is the "Slip-in" design. Forget about hunting for a wrench every time you need to change a tip or clean it. These tips simply slide into the torch head and tighten by hand. The nut retains the tip securely, and the internal gas pressure helps seat it firmly during use. This means faster changeovers and less downtime. Plus, the slip-in design protects the torch head from the wear and tear of stripped threads, extending the life of your entire cutting attachment.

Durability is built-in. The tip features a recessed, concave end that protects the flame holes from getting banged up if you accidentally touch the plate. It also helps keep the tip cool and reduces the chance of popping or backfiring when you are working in tight corners or on dirty metal. Compatible with popular attachments like the MC505, MC509, and DG109A, the MC12-5 is an essential addition to your torch kit. Whether you are cutting scrap or fabricating heavy machinery, this genuine Smith tip delivers the performance and safety you trust.
