Cutting Torch Tip Size Chart
Safety note: oxy-fuel cutting involves fire, hot metal, compressed gas, and flashback risk. Use manufacturer instructions for your torch, regulators, check valves, flashback arrestors, tip series, and fuel gas. This chart is a planning reference, not a substitute for the tip maker’s chart.

Before Selecting A Cutting Tip
- Match the tip series to the torch and fuel gas.
- Choose the tip from the metal thickness and the manufacturer’s cut chart.
- Check acetylene withdrawal limits for the cylinder size.
- Clean the tip with the correct tip cleaner, not random wire or drill bits.
- Use proper PPE and keep combustibles away from the cutting area.
