1. How much does oxy acetylene cutting training cost?
Our oxy acetylene cutting training costs R8,500 per person for the four-week programme. The course introduces learners to oxy acetylene equipment, gas handling, flame adjustment, cutting techniques, metal preparation and workshop safety.

2. What is oxy acetylene cutting?
Oxy acetylene cutting is a thermal metal-cutting process that uses a combination of oxygen and acetylene gas to generate a high-temperature flame. The flame preheats the metal, while a separate stream of high-purity oxygen reacts with the heated steel and removes the oxidised material to create a cut.

The process is commonly used to cut carbon steel and is widely applied in metal fabrication, construction, engineering and industrial maintenance.

Common applications include:

• Cutting steel plates and sheets.

• Cutting structural steel beams and sections.

• Preparing metal components for welding and fabrication.

• Cutting steel pipes and profiles.

• Dismantling unwanted steel structures.

• Repairing and modifying metal components.

3. Is oxy acetylene cutting difficult to learn?
Oxy acetylene cutting requires an understanding of gas pressures, flame adjustment, torch positioning and cutting speed. Beginners need to learn how to prepare the equipment, establish the correct flame and control the oxygen cutting stream.

Important skills include:

• Identifying torch components and their functions.

• Understanding oxygen and acetylene gas supplies.

• Adjusting gas pressures correctly.

• Establishing and recognising the required flame.

• Preheating metal before cutting.

• Controlling torch angle, distance and movement.

• Maintaining a consistent cutting speed.

• Recognising common cutting defects.

4. What does an oxy acetylene cutting course cover?
The course introduces learners to the equipment, procedures and techniques used in oxygen-acetylene cutting. Key learning areas include:

• Principles of oxy acetylene cutting.

• Oxygen and acetylene gas properties.

• Gas cylinders, regulators and pressure gauges.

• Cutting torch components and nozzle selection.

• Gas hoses, connections and flashback arrestors.

• Gas pressure and flow control.

• Flame types and flame adjustment.

• Metal preparation and cutting positions.

• Preheating and oxygen cutting techniques.

• Straight-line and profile cutting principles.

• Cutting speed and torch movement.

• Identifying cutting defects.

• Equipment inspection and workshop safety.

5. How does the oxy acetylene cutting process work?
Oxy acetylene cutting works through a combination of preheating and oxidation. The acetylene flame heats the steel to the required ignition temperature. A separate high-pressure oxygen jet is then released through the cutting torch.

The oxygen reacts with the heated steel, producing iron oxide. The oxygen stream blows away the molten oxide and other material, allowing the cut to progress through the metal.

The main stages include:

• Equipment preparation: Inspecting the cylinders, regulators, hoses, connections and cutting torch.

• Gas adjustment: Setting suitable oxygen and acetylene pressures according to the equipment and cutting requirements.

• Preheating: Heating the steel with the acetylene flame.

• Oxygen release: Activating the cutting oxygen stream once the steel reaches the required temperature.

• Cutting movement: Moving the torch along the intended cutting line at a controlled speed.

• Finishing: Allowing the material to cool safely and inspecting the cut edge.

6. What equipment is used for oxy acetylene cutting?
Oxy acetylene cutting requires specialised equipment to store, regulate and deliver oxygen and acetylene safely.

Common equipment includes:

• Oxygen gas cylinder.

• Acetylene gas cylinder.

• Oxygen and acetylene regulators.

• Gas pressure gauges.

• Oxygen and fuel gas hoses.

• Cutting torch and cutting attachment.

• Cutting nozzles and tips.

• Flashback arrestors and non-return valves.

• Approved spark lighter.

• Clamps and workholding equipment.

• Suitable cutting face protection, gloves and protective clothing.

All equipment must be inspected and operated according to the manufacturer’s instructions and applicable gas safety procedures.

7. What metals can be cut using oxy acetylene?
Oxy acetylene cutting is primarily used for carbon steel and suitable low-alloy steels. The process works because iron in the steel reacts with oxygen at high temperatures, allowing the material to be removed by the oxygen stream.

Common materials include:

• Mild steel plates and sheets.

• Carbon steel sections.

• Structural steel beams.

• Steel pipes and profiles.

• Suitable low-alloy steel components.

Ordinary oxy acetylene cutting is generally unsuitable for aluminium and stainless steel because these metals do not respond to the oxidation process in the same way as carbon steel.

8. What are the common challenges in oxy acetylene cutting?
Oxy acetylene cutting requires correct gas settings, flame adjustment and controlled torch movement. Common problems include:

• Incomplete cuts: Incorrect oxygen pressure, insufficient preheating or unsuitable cutting speed can prevent the cut from passing through the material.

• Rough cutting edges: Incorrect torch movement or cutting speed can produce uneven edges.

• Excessive slag: Poor cutting conditions can leave unwanted oxidised material attached to the underside of the cut.

• Excessive kerf width: Incorrect nozzle selection or torch positioning can produce a wider cut than required.

• Distortion: Excessive heat can cause thin steel components to bend or change shape.

• Flashback: A dangerous condition in which the flame travels backwards into the torch or gas system, requiring immediate action according to the equipment’s safety procedures.

Correct equipment inspection, suitable gas pressures and proper cutting techniques help prevent these problems.

9. Where can an oxy acetylene cutting operator work?
Oxy acetylene cutting is used in industries that process, manufacture, repair and dismantle steel components and structures.

Work environments include:

• Steel fabrication workshops.

• Construction and engineering companies.

• Manufacturing plants.

• Industrial maintenance facilities.

• Heavy equipment repair workshops.

• Metal recycling and dismantling operations.

• Shipbuilding and repair facilities.

• General metal fabrication businesses.

10. What career opportunities are available after oxy acetylene cutting training?
Oxy acetylene cutting training provides foundational knowledge for individuals interested in metal cutting, fabrication and industrial workshop operations.

Potential job opportunities include:

• Oxy acetylene cutting operator.

• Flame cutting assistant.

• Steel cutting worker.

• Metal fabrication assistant.

• Workshop assistant.

• Manufacturing assistant.

• Industrial maintenance assistant.

• Metal processing worker.

Further workplace experience and specialised training can help learners develop additional skills in welding, fabrication and metalworking.

11. Can I get an oxy acetylene cutting certificate after training?
Yes. Learners who successfully complete the required course assessments receive a training certificate confirming completion of the oxy acetylene cutting programme. The certificate can be included in a CV when applying for opportunities in metal fabrication, construction, manufacturing and industrial environments.

12. What are the requirements for oxy acetylene cutting training?
The course is suitable for beginners and individuals interested in learning oxygen-acetylene cutting techniques. Previous welding or metal fabrication experience is useful but is not essential for understanding the introductory principles.

Learners should be prepared to:

• Follow workshop instructions and safety procedures.

• Understand basic measurements.

• Learn how to handle gas cylinders and cutting equipment.
