How to use Oxy-Acetylene Cutting Torch

Oxy-acetylene cutting is a process used to cut through metals by combining oxygen and acetylene gases that produce an extremely high-temperature flame. The oxy-acetylene cutting torch can be used to cut steel, stainless steel, aluminium, brass, copper, titanium and other non-ferrous metals. It’s important to understand the process before getting started in order to ensure proper safety precautions are taken. Let’s take a look at how it works.

Setting Up the Torch

Before you begin oxy-acetylene cutting, you need to make sure the tools are properly set up. Start by attaching the oxygen and acetylene hoses to the regulators on each cylinder, respectively. Then attach one end of each hose to the torch handle and tighten them with wrenches or pliers. Make sure all connections are secure before proceeding any further. Once everything is connected properly, open both oxygen and acetylene valves until they reach 10 PSI (pounds per square inch). You can then adjust the preheat flame for a neutral flame by adjusting both gas knobs together until you get an even mix of oxygen and acetylene in the flame.

Using Your Torch

Once your torch is set up correctly, you can start using it for cutting various types of metal. To begin cutting metal, place your tip a few inches away from where you want to start your cut and turn on your preheat flame until it melts through the metal surface. Once there’s an opening in the metal surface that’s big enough for your tip size, move closer while still keeping a distance of around 1/8th inch between your tip and metal surface until you start hearing a hissing sound coming out of the molten metal – this means that your tip is in its optimal position for cutting through metals quickly without losing heat or risking damage or injury due to flying sparks or splattering molten metal droplets. Once this happens, slowly move around in different directions while keeping consistent pressure on your trigger until you finish making your desired cuts in whatever shape or size you need.


Oxy-acetylene welding is a great way to create intricate shapes from various types of metals quickly and efficiently. However, it’s important to make sure everything is properly set up before beginning so that no accidents occur during use. Be sure to follow all safety precautions when using an oxy-acetylene torch, as any misuse could result in serious injury or property damage! With some practice, anyone can become an expert at oxy-acetylene welding in no time!
