For cutting with an oxy-fuel torch, the oxygen cutting valve should be fully open, and the preheat flames should be adjusted to neutral (not oxidizing or carburizing) by balancing the oxygen and fuel gas at the torch. The exact pressure settings depend on the tip size and material thickness, but typically, oxygen is set between 20-40 psi and fuel gas (like acetylene) between 5-10 psi. Always follow the manufacturer's recommendations for your specific torch and tip.
