How do cutting torches work?

In oxy-fuel cutting, a torch is used to heat metal to its kindling temperature. A stream of oxygen is then trained on the metal, burning it into a metal oxide that flows out of the kerf as slag.

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. When shut down properly, this procedure can help detect even a minute leak in either the fuel or oxygen valve.

Which material Cannot be cut by the oxyfuel process?

Mild steel is comprised of 98% iron, 1% manganese, carbon up to . 3% and various other elements in small amounts. Oxy-fuel cutting cannot cut non-ferrous metals such as aluminum, stainless, brass or copper. Elements such as chromium, nickel, molybdenum inhibit the ability to cut steel with the oxy-fuel process.

What metals can be cut with oxy acetylene?

Oxy-acetylene can cut only low- to medium-carbon steels and wrought iron. High-carbon steels are difficult to cut because the melting point of the slag is closer to the melting point of the parent metal, so that the slag from the cutting action does not eject as sparks but rather mixes with the clean melt near the cut.

Is acetylene bad to breathe?

The symptoms of acetylene inhalation include diz- ziness, headache, fatigue, nausea, vomiting, tachycardia and tachypnea [2]. Exposure to a high concentration of acetylene may result in a loss of consciousness and death [1] . Acetylene is a colorless gas commonly used for welding.

Does acetylene burn 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 ratio of oxygen to acetylene?

2 to 1

What pressure should I set my cutting torch?

RULE OF THUMB (MULTI-HOLE CUTTING TIPS, OXY / ACETYLENE)

Recommended oxy/acetylene cutting tip pressures vary with size. If you have no manufacturer setting- information, and are cutting less than 1 ½” thick steel, set the acetylene regulator for 10 psig, and the oxygen regulator for 40 psig.
