Smith MC12 Series Size 00 Acetylene Tip

Reliable Cuts with Smith's Slip-In Technology

Get the job done right with the Smith MC12-00 Acetylene Cutting Tip, a staple for any welder using Smith medium-duty equipment. This Size 00 tip is your go-to solution for general purpose cutting on thinner gauge materials, capable of slicing through steel up to 3/16 inch thick with ease. Whether you are working on HVAC ducting, light fabrication, or automotive repair, the MC12-00 delivers the focused flame and clean cut you need to minimize grinding and cleanup time.

One of the biggest frustrations in the shop is searching for the right wrench to change a tip. The MC12-00 eliminates this hassle completely with its innovative Slip-In design. You can swap out tips in seconds by hand—just loosen the nut, slide the old tip out, slip the new one in, and hand-tighten. The tip rotates freely 360 degrees before tightening, allowing you to position the preheat holes exactly where you want them for the best visibility and performance. This feature alone saves time and frustration during multi-stage projects.

Durability is built into every aspect of this tip. Constructed from heavy-duty copper, it withstands the high heat of oxy-acetylene welding and cutting. The smooth, swaged interior resists slag build-up, meaning you spend less time cleaning your tip and more time cutting. When cleaning is necessary, the slip-in design allows for easier access from the back of the tip, ensuring you can clear obstructions without damaging the delicate front orifices. The soft flame characteristics of the MC12 series make starting cuts on the edge or in the center of a plate easier and more controlled.

Designed for use with Smith's popular medium-duty handles and attachments (such as the MC509 and WH100 combo), this tip ensures your equipment runs at peak efficiency. The in-tip mixing adds a layer of safety that gives you peace of mind, knowing that the mixed gas volume is kept low to prevent dangerous flashbacks. Upgrade your cutting setup with genuine Smith consumables for consistent, high-quality results.
