Smith MC12-5 Cutting Tip for Acetylene

The Smith MC12-5 is a one-piece cutting tip sized at 5 for handheld oxy-acetylene torches. It is built for operators who need a medium preheat flame to cut steel between 5 in and 6 in thick. The tip works with CC509P, DG109A, MC505 and MC509 cutting attachments from the same manufacturer.

Check torch and gas supply before ordering

Confirm your cutting attachment is one of the compatible models listed so the tip seats correctly. Your acetylene regulator must deliver 10 psig and your oxygen regulator 80 to 90 psig to match the tip’s pressure ratings. Verify the torch can supply 13 scfh acetylene and 15 scfh oxygen for preheat, plus 420 to 485 scfh oxygen for the cutting stream.

California Proposition 65 warning applies

The product carries a Proposition 65 notice for chemicals known to cause cancer and reproductive harm. No additional accessories, software or consumables are bundled with the tip itself. The warning informs safe handling and ventilation practices but does not change the tip’s mechanical function or compatibility.

Questions about this item

Does the MC12-5 cutting tip arrive with any extra seals or adapters in the box?

The tip is supplied as a single one-piece unit; no additional seals, adapters or attachments are included.

When should I select the Size 5 tip instead of another size in the MC12 series?

Choose the Size 5 tip when you need to cut material between 5 in and 6 in thick using acetylene at the listed flow and pressure settings.

What do the 13 scfh pre-heat acetylene and 420 to 485 scfh cutting oxygen figures mean on the job?

They tell you the gas consumption rates to set on your regulators so the tip delivers a medium pre-heat flame and the correct cutting oxygen volume for 5 in to 6 in steel.
