CNC Oxy/Fuel Guide takes the guesswork out of tip sizing for oxy-fuel cutting. Pick your fuel gas (acetylene or propane), manufacturer — Victor, Harris, Smith, ESAB, or Koike — and material thickness, and get the right tip size and gas pressures instantly instead of hunting through a paper chart on the shop floor. $0.99/year with a free 3-day trial.
Every oxy-fuel table operator I know has a tip chart taped to the wall somewhere, usually for one brand of tip. Built this so the right tip size and pressure is a couple taps away, across the manufacturers people actually run. Open to feedback on which manufacturers/gas combos to add next.
