What pressure should the oxygen regulator be set at for routine cutting PSI?
For cutting, use 40 psi for the oxygen and 5 psi for the acetylene.
What do you set oxygen and acetylene torches at?
Open the acetylene valve on the torch handle about 1/8 turn, or 45 degrees. Light the torch with a spark lighter and adjust the acetylene valve on the torch handle and the oxygen valve on the cutting torch until the flame has no yellow areas and the center is bright blue and well defined.
What pressure should oxygen and acetylene be set at for welding?
Before starting, each tank should read zero psi. To start the flame, the valve of the acetylene tank is rotated about a quarter of a turn to apply pressure to the regulator. Then the acetylene pressure is increased to 7 psi. Next, the oxygen gas valve is fully opened and then its regulator is adjusted to 40 psi.
What is the best way to set the oxygen pressure for cutting?
What is the best way to set the oxygen pressure for cutting? Make sure the oxygen cylinder is secure and open the valve all the way. What metals can be cut with the oxyfuel gas process?
What should my cutting torch be set at?
Recommended oxy/acetylene cutting tip pressures vary with size. If you have no manufacturer setting- information, and are cutting less than 1 ½” thick steel, set the acetylene regulator for 10 psig, and the oxygen regulator for 40 psig.
How do you adjust an oxygen and acetylene regulator?
For the oxygen, turn the pressure-adjusting screw on the regulator until the gauge reads about 25 psi. For the acetylene, turn the pressure-adjusting screw on the regulator until the gauge reads about 10 psi.
What should my torch regulators be set at?
What is the ratio of oxygen and acetylene in gas cutting?
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 is oxygen acetylene ratio?
Explanation: Oxygen to acetylene ratio in case of neutral flame by weight is 3 ∶ 1.
What is the ratio of oxygen to acetylene in a neutral flame?
one-to-one ratio
The neutral flame has a one-to-one ratio of acetylene and oxygen. It obtains additional oxygen from the air and provides complete combustion. It is generally preferred for welding.
How to set the oxy acetylene regulators?
How to Set Up an Oxy-Acetylene Torch. Secure the oxygen and acetylene tanks in the torch cart. Remove the covers protecting the tank valves and attach the regulators to the valves. Attach the hoses to the regulators. Connect the other end of the hoses to the torch handle. Turn the valve on the oxygen tank completely open.
How do you set up an acetylene torch?
– Turn off the gasses supplies by switching off the valves at their respective tanks. – Purge the gas that remains in both hoses or gas lines by reopening the oxygen valve on the torch so that the remaining gas in the hose will flow out. – Repeat the purging with the other gas line. – Once you finish purging, disconnect all components and store them properly.
Does acetylene burn without oxygen?
Does acetylene burn without oxygen? Decomposition is a chemical reaction whereby acetylene breaks down into its constituent elements, carbon and hydrogen. This reaction gives out a great deal of heat, which can cause the gas to effectively ignite without the presence of air or oxygen.
Why is an acetylene torch hotter than a propane torch?
Which is hotter acetylene or propane? Acetylene releases nearly 40% of its warmth within the internal flame cone. Due to this fact, acetylene is best for reducing than propane. Whereas temperature sensible acetylene is hotter than propane the very fact is that persons are utilizing propane for reducing incorrectly.
