What is a Cutting Torch?
A cutting torch is a tool that uses a combination of fuel and oxygen to create a powerful, high heat flame. The flame is used to cut through a wide variety of materials including metal, stone, and brick. The cutting torch is often referred to as an “oxy-fuel cutter,” as the flames are created by combining oxygen with a fuel such as acetylene, propane, or natural gas. The cutting torch usually consists of a torch handle, a fuel hose, and an oxygen hose, each of which is connected to the corresponding tanks.
The best way to use a cutting torch is with a “tip,” which helps to concentrate the flame and direct it more accurately. The size of the tip is determined by the thickness of the material being cut, with larger tips being used for thicker materials. The cutting torch also requires fuel pressure and oxygen pressure to be adjusted correctly – too much pressure can cause the torch to overheat and be dangerous, while too little can cause an inefficient cut.
What is a Plasma Cutter?
A plasma cutter is a tool used to cut through materials using an electrical arc. It works by sending a high-velocity plasma arc through a narrow opening in the electrode, creating a cutting current for the material being cut. The plasma is created using a compressed air source, usually from an air compressor or an air pump, which is fed through the electrode and compressed gas supply to generate the plasma arc. The cut is smooth, with almost no sparks and minimal heat input, making it ideal for a variety of projects. It is also generally easier to work with and more precise than a cutting torch, as it produces a thinner, more precise cut than a flame can.
Pros and Cons of a Cutting Torch

Cutting Torch vs. Plasma Cutter – Cut Quality
Cutting torches are known to produce rougher, more uneven cuts with more heat input than plasma cutters. Additionally, when cutting thinner materials, the human factor can come into play, as the flame has to be adjusted frequently to create the required level of cut precision and accuracy.
In contrast, when using a plasma cutter, the cut is more precise, with the machine and its settings doing the most of the work. The plasma cutter’s arc is narrow and able to create intricate designs and thinner cuts with ease, resulting in less slag or burrs in the edge of the cut.
Overall, plasma cutters are preferred if cut quality is the most important factor. If you are looking for quick, accurate and clean cuts then a plasma cutter is an ideal choice. However, if cost is a major factor then a cutting torch may be the way to go.
Cutting Torch vs. Plasma Cutter – Durability
Cutting torches have a much longer lifespan than plasma cutters, generally lasting ten years or more due to their simple design and robust construction. Heavy metal frames and tanks are used to provide them with superior strength and durability. On the other hand, most plasma cutters have relatively short lifespans, usually three to five years, as the electronics and components are subject to greater wear and tear.
Both cutting torches and plasma cutters require regular maintenance to ensure regular output, however, the maintenance requirements for cutting torches can be more intensive. Cutting torches require frequent changing and adjustment of tip parts and fuel and oxygen lines, while plasma cutters require regular cleaning of the electrode and tip to prevent build up and maintain efficiency.
Overall, the durability of cutting torches tends to outweigh the durability of plasma cutters, however, when considering the overall maintenance costs, many users opt for a plasma cutter due to the reduced costs in terms of parts replacement and upkeep.
Cutting Torch vs. Plasma Cutter – Portability
When it comes to portability, plasma cutters are more convenient and less cumbersome compared to cutting torches. Cutting torches require access to an external fuel source and require a larger setup for proper operation, making them less suitable for on-site jobs. Plasma cutters, on the other hand, often come in smaller, more compact sizes and can operate off of a variety of power sources, making them easier to transport and use in a multitude of locations.
Cutting Torch vs. Plasma Cutter – Safety
Using cutting torches comes with the risk of severe burns and explosions due to flammable gasses and open flame used by the torch. Therefore, it is important to always wear protective clothing and fireproof gloves when working with torches. Always keep a fire extinguisher nearby.
