Miller-Smith SC12-1 Acetylene Cutting Tip

The Miller-Smith SC12-1 is a one-piece acetylene cutting tip designed for handheld or machine torches. It covers a cutting range from 1/2 inch to 5/8 inch thick material. The tip fits DG and SC series torches and SC205 or SC209 cutting attachments. It serves general-purpose metal cutting tasks.

Simple thread-on installation with series match

Installation requires matching the SC12 tip series to your torch and attachment series. The tip threads onto compatible DG or SC torches fitted with SC205 or SC209 attachments. Problems arise when operators use mismatched series or incorrect fuel-gas pressure settings for acetylene. Clean threads and proper seating prevent gas leaks and unstable flames.

Steady cutting through 1/2 to 5/8 inch plate

Under sustained cutting the tip maintains a stable acetylene flame across the rated thickness range. The one-piece construction resists tip-end overheating during long passes. Consistent gas flow preserves cut quality without frequent pressure adjustment. Performance drops if the tip orifice fouls or if supply pressure drifts during extended use.

Questions about this item

How can I confirm the SC12-1 cutting tip is cutting correctly after fitting it to my torch?

A steady, neutral flame and a clean kerf with minimal slag on 1/2 to 5/8 in plate show the tip is working as intended.

What comes with the SC12-1 cutting tip and what must I supply separately?

The box contains the one-piece SC12 size 1 tip only; you must provide a compatible DG or SC series torch and acetylene fuel supply.

Which tip size should I choose for cutting 1/2 to 5/8 in material with acetylene?

Select the SC12 size 1 tip, which is rated for 1/2 to 5/8 in thick plate when used with acetylene on DG or SC series torches.
