What should the acetylene pressure be to light a torch?

What should the acetylene pressure be to light a torch?

The maximum working pressure for acetylene gas when using a cutting torch is 15 psi or 103.4 kPa.

Does oxygen or acetylene light first?

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

How far should you open the acetylene torch valve when lighting the torch?

The cylinder valve should only be opened 3/4 of a turn. The acetylene cylinder should never be laid down as this will result in the gas becoming unstable.

Is acetylene flammable or explosive?

Hazard Class: 2.1 (Flammable) Acetylene is a FLAMMABLE GAS. Stop flow of gas or let fire burn itself out. POISONOUS GASES ARE PRODUCED IN FIRE, including flammable Hydrogen gas. CONTAINERS MAY EXPLODE IN FIRE.

Can you use acetylene 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.

What is the maximum working pressure that may be set for acetylene?

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 I set my cutting torch?

NOTE: Most torch mixers use a “positive” design that requires fuel gas pressures set between 5-15 psi for cutting applications. However, some torches use an injector (low pressure) mixer design that only requires ¼ – 2 psi of alternate fuel gas.

Can you smell acetylene?

Acetylene is a colorless and odorless gas. Commercial grade Acetylene may have an Ether-like or garlic-like odor.

What’s the best way to light a torch?

Done right, it lights to a flame with enough oxygen already there so it’s not sooty. Done wrong, you get a nice loud bang. The trick is just to use a tiny bit of oxygen. Just open the oxygen valve enough so it’s no longer closed tightly. Then, if it’s still too yellow and sooty, the valve will at least be quick to open further.

How to light a small oxy-acetylene torch?

But open the acetylene valve just enough to light, and then also barely crack open the oxygen valve. Done right, it lights to a flame with enough oxygen already there so it’s not sooty. Done wrong, you get a nice loud bang. The trick is just to use a tiny bit of oxygen.

How do you set up a cutting torch?

Once the hoses are firmly in place, connect the other ends of the hoses to the handle of your torch. Connect your cutting torch to its handle and tighten the nut by hand. Ensure that the valves on both the torch and the handle are closed. After setting up, you still need to do some checks before attempting to light your cutting torch.

How is the oxygen connected to the torch?

Attach the oxygen hose to the oxygen regulator and to the torch. The torch should have identifying marks on the body or the handle showing where the hose should be connected. Most torches have 2 oxygen connections because 1 is used for the cutting jet and 1 is used for the preheat flames.
