What pressure should acetylene gas be used at?
What pressure should acetylene gas be used at?
Never use acetylene at pressures above 15 psi. Using acetylene at pressures in excess of 15 psi gauge pressure (or about 30 psi absolute pressure) is a hazardous practice. To do so is contrary to insurance regulations and is prohibited by law in many places.
What pressure should torches be set at?
NOTE: Most torch mixers use a “positive” design that requires fuel gas pressures set between 5-15 psi for cutting applications. However, some torches use an injector (low pressure) mixer design that only requires ¼ – 2 psi of alternate fuel gas.
When finished with an oxy acetylene torch set which gas should you turn off first?
“Which gas do you turn off first?” We get this question a lot out in the field, and it’s a good one. This blog entry outlines our recommendations for proper shut down of an oxy-fuel torch. We recommend closing the oxygen valve first whenever turning off an oxy-fuel torch system especially when Acetylene is fuel.
What should my oxy acetylene regulators be set at?
The recommended setting is for the fuel gas regulator to be set at 10 psig and the oxygen regulator at 45 psig.
What PSI should oxy acetylene?
The gas pressures should be set at 3 to 5psi for Acetylene, and 20 to 30psi for the oxygen, but when you squeeze the oxygen lever after the initial flame adjustment of the preheat flames to neutral just to a point where the feather disappears,the oxygen cutting stream should be visible and at least 4 inches in length …
What is the ratio of oxygen to acetylene?
1.2:1
Natural Gas
| Table : Fuel Gas Characteristics | ||
| Fuel Gas | Maximum Flame Temperature °C | Oxygen to fuel gas Ratio (vol) |
|---|---|---|
| Acetylene | 3,160 | 1.2:1 |
| Propane | 2,828 | 4.3:1 |
| MAPP | 2,976 | 3.3:1 |
What pressure should oxygen and propane be set at for cutting?
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 with the use of propane, propylene or natural gas.
What is the working pressure for the oxygen gas of the cutting rig?
10 to 40 psi
The oxygen pressure ranges between 0.7 to 2.8 bar (10 to 40 psi), depending on the size of the torch tip. A jet of relatively high-pressure oxygen produces the suction necessary to draw the fuel gas into the mixing head. The welding tips may or may not have separate injectors in the tip.
