How to Cut Steel with an Acetylene Torch?

An acetylene torch is a powerful tool used to cut through steel and other materials. When cutting steel, it can be tricky to do it correctly and safely. This blog post will provide information on how to cut steel with an acetylene torch and suggestions for safety precautions you should take when using one.

Safety First!

Before cutting steel with an acetylene torch, ensure you have the proper safety equipment. Protective eyewear is a must, along with gloves and a face shield or welding mask. Make sure the area where you work is free from combustible material and has good ventilation. Please read the manual for your specific torch model to better understand its operation and safety features.

Setting Up Your Torch

Once your safety equipment is in place, you can begin setting up your acetylene torch. Attach the oxy-acetylene hoses to the appropriate tanks and connect them to the torch handle. Open both valves slowly and check for gas leaks by spraying soapy water over all connections. Once everything has been reviewed, and there are no leaks, light the torch using a spark lighter or matches, depending on what type of ignition system your model has.

Cutting Steel

When cutting steel with an acetylene torch, adjust the flame length according to how thick the material being cut is; longer flame lengths are best for thicker materials, while shorter flames are better for thinner materials such as sheet metal or tubing. Point the tip of the love at an angle towards the steel at about a 45-degree angle; this helps heat up more area around the cutting line, making a cleaner cut. Move along the cutting line slowly but steadily until you reach your desired depth; be careful not to overheat any areas, as this could cause warping or distortion of the cut material. After each cut, turn off your torch immediately to avoid accidents from open flames in your workspace.


Cutting steel with an acetylene torch requires patience, skill, and knowledge of safety protocols to complete projects without injury or damage to property. With practice and experience using an acetylene torch comes confidence in knowing how long each flame length should be set before beginning a cut and how deep each amount needs to be made without damaging surrounding areas of material or components within them. These precautions will ensure that every project completed with an acetylene torch will be safe and successful!
