🔥 Oxy-Fuel Cutting Tip Size & Gas Pressure Calculator

Victor-style acetylene tip numbers, oxygen/fuel PSIG, and travel speed for mild steel

Estimate cutting tip size, oxygen cutting pressure, fuel gas pressure, and approximate travel speed from plate thickness and fuel type. Acetylene uses Victor-style one-piece tip numbering (000, 00, 0, 1, 2…). Harris, ESAB, and other brands use different tip codes — verify against your torch manufacturer chart.

For plasma parameters on the same thickness, see the Plasma Cutting Calculator. Process choice: Oxy-Fuel vs Plasma Cutting.

Catalog gaps (no CSV match with verified image): oxy-fuel cutting tips (Victor/Harris/ESAB sizes), oxygen cutting regulators, acetylene/LP fuel regulators, and flashback arrestor sets. TestTalkHQ does not pad this section with mismatched plasma cutters or TIG torch kits. When those SKUs are added to the affiliate CSV, this page will be updated.

How Oxy-Fuel Tip Sizing Works

Oxy-fuel cutting preheats mild steel with fuel gas and oxygen until the metal reaches kindling temperature, then a high-velocity oxygen jet oxidizes the iron and blows molten oxide from the kerf. Tip size controls preheat flame volume and oxygen orifice capacity — too small and you cannot maintain the cut; too large wastes gas and widens the HAZ.
