Take a look at the oxy-acetylene pressure settings chart to understand what your torch should at for the most optimal results. The recommended setting is for the fuel gas regulator to be set at 10 PSIG and the oxygen regulator at 45 PSIG. This recommendation applies when cutting less than 1.5-inch steel using propane, propylene, or natural gas.

* Pressure is measured at the torch inlet on MTH Series Tips. Torchs with flashback arrestors require up to 25% more pressure as tip size increases.

Tables show approximate gas pressures for welding or cutting. Tip size numbers vary among manufacturers, so orifice sizes are shown in "number drill" sizes.

Setting the correct working pressures. Adjust to the correct flame setting. Make use of correct welding & cutting technique. There are a number of different types of oxy-acetylene torches on the market. The most popular and common design in the …

Torches equipped with a flame backflow preventer (“flashback arrestor”) may require a pressure up to 25% higher than indicated in the chart. Ensure never to exceed 15 PSI for acetylene. *** All pressures are measured at the pressure regulator with a 3/8 inch, 25 feet long hose.

The Harris Cutting Tip Chart contains information on tip style/size selection, oxygen gas pressure settings (pre-heat flame and cutting stream), cutting oxygen gas orifice (center hole) sizing, fuel gas pressure settings, hose size recommendation, …

Cutting tips come in different sizes so you'll need to look at a chart depending on what thickness metal you will be cutting. The thicker the metal, the more pressure you need to get all the way through.

With a 2-hose cutting torch, preheat pressure is set by the cutting oxygen. ** For best results use appropriate capacity torches and 3/8" hose when using tip size 6 or larger. Torches with flashback arrestors require up to 25% more pressure as tip size …
