What pressure should acetylene torches be set at?
What pressure should acetylene torches be set at?
3 to 5psi
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 …
Why does my cutting torch keep popping?
The reason that an oxyacetylene cutting torch will pop and go out is because of a problem with gas flow. Usually this is either an issue with flow settings, a leak or blockage.
How do I know if my acetylene tank is empty?
In order to tell if a welding tank is almost empty, read the gauge! Often measured in pound-force per square inch (psi), the gauge will tell you that the pressure is decreasing. Notice the pressure your tank is at when full, this could be 1000 psi. When it reaches 500 psi you will know it is half way empty.
What is the best way to set the oxygen pressure for cutting?
What is the best way to set the oxygen pressure for cutting? Increase the pressure slowly and readjust the flame as you watch the length of the clear cutting stream in the center of the flame.
What happens to acetylene above 15 psi?
Acetylene is highly flammable under pressure and is spontaneously combustible in air at pressures above 15 psig. Acetylene cylinders do not contain oxygen and may cause asphyxiation if released in a confined area.
What is the difference between an oxygen and acetylene regulator?
Probably the most obvious difference is the screw threads. Regulators for combustible gases (Acetylene, Propane, Propylene etc), usually have Left Hand Threads. Regulators for non combustible gases (Oxygen, Argon, Co2 etc), usually have Right hand Threads and as such do not have the cuts on the Hexagon.
What do you do if the torch starts popping?
Lighting Procedure
- Purge both lines individually.
- Open the acetylene torch valve half a turn.
- Light the torch with a flint striker.
- Increase the gas flow until there is no smoke and the flame leaves the tip of the torch.
- Decrease the flow until the flame returns to the tip of the torch.
What should I set my cutting torch 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.
