What pressure should oxygen and Acetylene be set at?

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 do you turn on first oxygen or Acetylene?

We recommend closing the oxygen valve first whenever turning off an oxy-fuel torch system especially when Acetylene is fuel. This is only part, but a very important part, of the complete safe operating procedure recommended for torches by Harris.

How do you adjust the pressure on an oxy Acetylene torch?

Turn the valve of the oxygen tank or cylinder until it is fully open. Locate the regulator’s adjusting screw and turn it clockwise until the gauge shows that the pressure being released is between 40 to 60 psi. For the acetylene cylinder, do a counterclockwise turn for the valve, but only a quarter of the way.

How do you set up oxygen and Acetylene gauges?

Do you use more oxygen or acetylene?

How thick can an oxy acetylene torch cut?

For maximum flame temperature in oxygen, the ratio volume of oxygen to fuel gas are 1.2 to 1 for acetylene and 4.3 to 1 for propane. So, there is far more oxygen being consumed when using propane than acetylene. Despite propane being less expensive than acetylene, this is counteracted by the higher oxygen consumption.

What pressure should a cutting torch be set at?

Oxy-fuel torches also offer versatility, as they are capable of cutting, welding, brazing, soldering, heating and gouging. The average hand-held system can cut steel 6 to 12 inches thick. However, some oxyfuel hand torches are able to cut steel more than 20 inches thick.

What should my torch regulators be set at?

CAUTION: Never exceed 15 pounds per square inch (psi) when using Acetylene. NOTE: Most torch mixers use a “positive” design that requires fuel gas pressures set between 5-15 psi for cutting applications.

What is the difference between an oxygen and acetylene regulator?

Why is my cutting torch popping?

What is the best way to set the oxygen pressure for cutting?

Acetylene regulators control the acetylene pressure from any standard commercial cylinder containing pressures up to 500 psi (3447.5 kPa). The acetylene regulator design is generally the same as that of the oxygen regulator, but will not withstand such high pressures.

How much PSI is in a full acetylene tank?

What causes a rosebud torch to pop?

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 you fix a cutting torch?

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.

How do I know if my torch is leaking?

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). You must always take temperature into account when estimating how much acetylene the cylinder contains.

What is the best cutting torch to buy?

Tip starvation of insufficient gas flow is the usual reason. A rosebud is designed to use a lot of oxygen and acetylene gas flow. As the tip heats, more inner tip ignition of gases will occur. This will produce a banging or popping sound, and can lead to a flashback.

Can an acetylene cylinder explode?

Brush the torch tip thoroughly with a wire brush to remove any debris or metal particles. If the torch tip is warped or flattened on the end, replace with a new tip. Clean the inside of the torch tip port holes with a torch tip cleaning tool. Clean all of the acetylene port holes and the center oxygen port hole.

How do you stop Rosebud?

What is the hottest cutting torch?

Acetylene is highly unstable. High pressure or temperatures can result in decomposition that can result in fire or explosion. Acetylene cylinders must never be transported or stored in a closed vehicle.

What is the best portable oxy acetylene torch kit?

If the flame tries to burn back into the tip it is quenched because it looses heat to the tip and the flame goes out. If you get the tip hot enough to overcome the heat loss at the opening then the flame can go into the tip POP and extinguish.
