Frequently Asked Questions

How do I select the right cutting tip size for my material thickness?

Cutting tip size is matched to material thickness. As a general guide: thin sheet (up to 1/4 in.) uses a small orifice tip with low oxygen and fuel pressure; 1/4–1 in. plate uses mid-range tips; heavy plate (1–6 in. or more) requires large-bore tips with high oxygen flows. Each tip manufacturer provides a chart in their tip documentation listing recommended oxygen and fuel pressure, tip number, and cut speed for each material thickness range. Always follow the tip maker's chart — not just tip size — because tip numbering systems differ by brand.

What is the difference between one-piece and two-piece (divergent) cutting tips?

One-piece tips have the cutting oxygen orifice and preheat flame holes machined into a single piece of copper. Two-piece tips use a separate inner piece (cutting oxygen tube) inside an outer shell (preheat holes). Two-piece tips are generally preferred for machine cutting because the cutting oxygen stream can be shaped for specific kerf geometries. One-piece tips are common on handheld torches and are simpler but offer less flexibility in orifice design.

Can machine cutting tips for acetylene also work with propane or natural gas?

No — tips are designed for specific fuel gases. Acetylene tips have a different preheat flame hole pattern optimized for acetylene's high flame temperature and localized heat. Propane and natural gas produce a larger, lower-temperature preheat flame and require tips with more preheat holes or a wider flame ring to achieve adequate preheat. Using an acetylene tip with propane typically results in poor cut quality, excessive dross, and difficulty maintaining the cut. Always use the tip type specified for your fuel gas.

What causes cutting tip damage, and how can it be avoided?

The most common causes of tip damage are backfire (tip seated improperly, allowing flame to burn inside the tip orifice), flashback (flame traveling back into the hose — prevented by flashback arrestors), tip contact with the workpiece, and spatter accumulation blocking the orifice. Keep tips clean with a tip cleaner file, ensure all connections are tight and leak-free, and never drag the tip on the plate during a cut. Replace tips that show enlarged or out-of-round cutting orifices, as these degrade cut quality.

What oxygen and acetylene pressures should I use with machine cutting tips?

Recommended pressures depend on the specific tip size and thickness being cut. As a starting reference from AWS guidance: for 1/4 in. plate, oxygen pressure typically runs 20–25 PSI; for 1 in. plate, 30–40 PSI; for 6 in. plate, 45–60 PSI. Acetylene working pressure must never exceed 15 PSI (above 15 PSI, acetylene becomes unstable and potentially explosive). Always set pressures per the tip manufacturer's chart and verify with a clean test cut.
