Snap cutters (or pipe cutters) are frequently used to cut cast iron and tend to be the chosen cutting method for plumbers and people who need to make many cuts on cast iron pipes.

There are much more efficient ways to cut cast iron, such as a snap cutter or diamond blade.

Furthermore, they cut with greater precision than oxy-fuel torches, enabling you to cut thinner metals without distortion.Īlthough plasma cutter torches can cut cast iron, they may cost up to $3,500 and may cause your electricity bill to surge. Unlike oxy-fuel torches, plasma torches can smoothly cut cast iron. Plasma cutters work by adding electricity to compressed air, which creates plasma gas that is conductive.Īdding more electricity makes the plasma cutter hotter and enables you to control how powerful you want the cut to be. Moreover, plasma cutters are faster than oxy-fuel torches because they do not require preheating. However, they can be used to cut cast iron and stainless steel, which oxy-fuel torches are unable to do. Plasma cutters are less commonly used than oxy-fuel torches because they only cut metals that are about an inch thick or less. With effort, you may be able to cut cast iron with an oxy-fuel torch, but it will probably be a very rough and uneven cut. These torches should not be used to cut metals like cast iron, aluminum, or stainless steel. Generally, oxy-fuel torches are used for heavy metals such as steel and are frequently used in scrap yards to cut scrap metals. When it is preheated, an oxygen jet creates a chemical reaction between the oxygen and the metal, allowing it to be cut. Oxy-fuel torches work by heating the steel to its ignition temperature using its oxygen gas flame. Oxy-fuel torches are extremely versatile, and they can cut much thicker metals than plasma torches- they can typically cut steel that is up to 20 inches thick.įurthermore, these torches can be used for cutting, welding, heating, and other purposes. Oxy-fuel torches are by far the most common torch used for cutting but are not usually used to cut cast iron.Ĭonversely, plasma cutters are much less common but have a unique advantage due to their ability to cut metals like stainless steel and cast iron. The main types of torches used for cutting are plasma cutter torches and oxy-acetylene torches (also called oxy-fuel torches). To do this, you can’t use your standard oxy-fuel torches but could use a plasma cutter torch. Types of Torches For Cutting Cast IronĬutting cast iron may be necessary because it is very heavy and prone to rusting.Įspecially because many pipes are made of cast iron, you may need to remove rusted sections and replace them or cut cast iron pipes before moving them.
