What should my oxygen and acetylene gauges be set on?

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 pressure do we set acetylene regulators to?

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 should oxygen pressure be set at?

For cutting everything is different and the oxygen pressure should be about 25 PSI.

What PSI should you never go above on the acetylene gauge?

Maximum pressure. Under no condition shall acetylene be generated, piped (except in approved cylinder manifolds) or utilized at a pressure in excess of 15 psig (103 kPa gauge pressure) or 30 psia (206 kPa absolute).

What pressure should oxygen and propane be set at for cutting?

Turn on the propane tank and oxygen tank. Adjust the psi on the oxygen regulator to around 40 psi. Adjust the psi on the propane tank regulator between 5 and 10 psi.

What do you turn off first oxygen or acetylene?

We recommend closing the oxygen valve first whenever turning off an oxy-fuel torch system especially when Acetylene is fuel.

What pressure should oxygen and Acetylene be set at for brazing copper?

Oxygen and acetylene should be set at equal delivery amounts depending on the size and mass of the object being brazed. This would translate into 5 psi oxygen and 5 psi acetylene. These pressures are delivery pressures that must be set as the gas is flowing from the torch tip.

What is the pressure in a full oxygen cylinder kPa?

390-400 kPa
medical oxygen a full cylinder should have a plastic stopper inserted in the valve outlet, or if a smaller cylinder, plastic tape wound around the outlet. the gas is delivered through a valve to a regulating device which reduces the pressure to a safe 390-400 kPa.

What is the working pressure of acetylene in PSI?

A full acetylene cylinder which has a pressure of 250 psi at 700F (1725 kPa at 20 C) will have a pressure of 315 psi at 900F (2175 kPa at 310C) and a pressure of 190 psi at 500 F (1300 kPa at 90C).

What is the ratio of oxygen and acetylene in gas cutting?

1.2:1
Natural Gas

What are typical cylinder pressures for oxygen and acetylene?

In case the recommended working pressure settings are not indicated, safe numbers are 40 psi for oxygen and 10 psi for acetylene, regardless of cutting tip size. Simply adjust them until you get a neutral flame, but pay close attention to the acetylene pressure to prevent it from exceeding the limit.

What is maximum safety working pressure for acetylene?

These reactions are exothermic and unlike other common flammables do not require oxygen to proceed. Consequently, acetylene can explode with extreme violence if the absolute pressure of the gas exceeds above 2 kg/sq cm. The safe limit for acetylene is 1.03 kg/sq cm .

Can you use oxygen and acetylene on same cart?

(1) No more than a single acetylene cylinder and a single oxygen cylinder are on a cylinder cart. The cylinder cart must be specifically designed to hold/carry oxygen and acetylene cylinders in the upright position. The cylinders must be securely held to the cart (such as by straps, chains or other securing device).

How to use oxy acetylene torch?

To create the flame,open the valve of acetylene. It should be half-turn.
