Torch settings for heating

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.

What pressure should acetylene torches be set at?

The adjustment of the pressure of the oxygen bottle must be set between 0.8 and 1.5 bar. The one for the acetylene bottle needs to be between 0.3 and 0.5 bar. You will then open the valves of your blowtorch.

What temperature should a cutting torch be?

It is approximately 6,000 °F (3,300 °C) and provides enough heat to easily melt steel. In the inner cone the acetylene breaks down and partly burns to hydrogen and carbon monoxide, which in the outer cone combine with more oxygen from the surrounding air and burn.

What should the oxygen Psi be on the torch?

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.

What should my propane and oxygen torch be set at?

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 should the pressure be on a propane torch?

The oxygen gauge should be set around 50 psi. Check the torch hoses and gauges for leaks, damage or deterioration.

How do you set oxy acetylene for heating?

Separately purge both oxygen and fuel gas lines.
Open fuel gas valve 1/2 turn.
Ignite flame with striker.
Increase fuel gas flow until flame leaves end of tip and no smoke is present.
Decrease until flame goes back to tip.
Open oxygen valve and adjust to neutral flame.
Depress oxygen lever and make necessary adjustments.

What happens when acetylene goes over 15 psi?

greater than 15 psig. A violent, explosive decomposition reaction can occur. pressure at or above 15 psig with red marking on the gauge. There are a number of incidents each year where a flashback into an acetylene cylinder triggers decomposition, leaving the cylinder in a dangerous, unstable condition.

Why should you not use acetylene over 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 do the numbers on a cutting torch mean?

The tip size number indicates the orifice size and the relative gas rate the tip is capable of producing. In this text, torch tip size is indicated by number drill sizes.

What is the ratio of oxygen to acetylene?

Fuel Gas	Maximum Flame Temperature °C	Oxygen to fuel gas Ratio (vol)
Table : Fuel Gas Characteristics
Acetylene	3,160	1.2:1
Propane	2,828	4.3:1
MAPP	2,976	3.3:1

Why is cutting torch 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.

Do you turn on oxygen or acetylene first?

You always turn on acetylene first, light it, and set the flame to a minimum. THEN you turn on the oxygen, and adjust the flame as required to correct it for either welding or cutting. You always turn OFF the Oxygen first, and then the acetylene.

What is the maximum psi you should use acetylene?

The working pressure of acetylene equipment is critical: Acetylene pressure must not exceed 0.62 bar (9psi) unless equipment has been specifically designed for it.

What PSI should the torch never go above on acetylene?

Never set the psi on your acetylene regulator higher than 15 psi. NEVER! Never let your tank run empty, especially when using it with oxygen. Oxygen can backpressure into the tank and cause an explosion.

What pressure should a propane regulator be set at?

Generally, propane pressure should be between 100 and 200 psi ensures that the liquid propane gas remains in a liquid state. Normally, the pressure inside a propane tank fluctuates slightly based on the outside temperature. For example, a standard 20-pound propane tank at 70 degrees will have 145 psi internal pressure.

What is the ratio of propane to oxygen?

For propane to burn effectively, the oxygen-to-gas mixture must be within a certain range. For ideal conditions, there should be four parts propane to 96 parts oxygen.

Which burns hotter oxygen or propane?

The simple answer to this question is yes. The maximum neutral flame for acetylene in oxygen is about 5720 F, while the temperature for propane is 5112.

What does 11 WC mean for propane?

What is WC Pressure? WC stands for Water Column and is measured in inches. It is a measurement of pressure under 1 PSI. Most gas companies deliver gas to your home at 11" WC. 27.7" WC is equal to 1 PSI.
