Plasma cutters look similar to welding machines, but instead of joining metal materials, a plasma cutter is used to cut through various metals quickly and accurately. Plasma cutters have continued to gain popularity in the metal fabrication industry due to their ability to cut any conductive metal with the desired speed and precision. It is a versatile tool and a must-have tool for any metal fabricator, and the best part is today’s machines are more powerful and lighter, and there are models for both professionals and hobbyists.
A plasma cutter uses an ionized gas torch to make a neat and accurate cut through electrically conductive materials. Ideally, your choice of the best plasma cutter will depend on the maximum thickness of the materials you’ll be cutting most and the scope of your projects, i.e., home use or industrial use. Working with a plasma cutter is a lot easier, and you don’t have to deal with a messy workplace, loud grinding, or rough and inaccurate cuts.

How to Choose the Best Plasma Cutter
A plasma cutter greatly improves your metalworking skills, but getting a cheap one may not get the job done. Choosing a high-end model may cost higher up-front, but this often translates into a lower cost of operation and better operation in the long run. So, this buying guide will help you understand some crucial factors that will help find the most suitable plasma for your needs. These are;
i. Cut thickness
The maximum cut thickness is one of the very first specifications you’ll want to consider when buying a plasma cutter. Ideally, cut thickness is presented into two different ratings, i.e., the clean cut and maximum severance cut. Clean cut is the maximum thickness the machine can comfortably accommodate while achieving smooth lines. On the other hand, the max severance cut refers to the absolute thickness that a machine can achieve when pushed to the limit. The max severance cut, however, results in a rough finish, so it is not recommended if you want clean, smooth cuts.
ii. Compressed air or gas?
Most traditional plasma cutters use gases such as Argon, Nitrogen, or Oxygen to initiate the cutting process. However, technology has made it possible to use compressed air, which much safer and easier to use. A plasma cutter can either have an inbuilt air compressor or a separate compressor, so it depends on your needs as to choose. When using compressed air, you’ll need to check the airflow and air pressure requirements of your plasma cutter and find a compressor that meets requirements. The air compressor should be able to offer sufficient CFM, usually 1.5 times more than the needs of your plasma cutter.
iii. The type of torch
Plasma torches serve a general purpose of slicing through metals come, but they come in different forms, with each type featuring a different approach of striking the arc. They include;
- Non-touch pilot arc: This type of torch creates the jet of plasma from a small distance away from the surface you are cutting and cuts through the section without touching the surface. This feature is called a pilot arc, and you can either maintain a constant distance or adjust the height depending on the type of cut needed. Pilot arc machines produce neat cuts while ensuring your nozzle remains clean.
- Drag torch: A drag torch technique requires you to cut through metals smoothly while the tip of the torch touches the metal you’re cutting. Without using the drag technology, the tip of the nozzle can stick to your project resulting in inconsistent cuts or stop the process altogether. Drag technology is best suited for decorative and artistic projects, as it makes it easy for you to trace lines and patterns when cutting.
- Touch start: A touch start system is similar to a drag system, but it uses a free hand to slid the nozzle across the metal while lifting it off the surface to finish the cut. This is the least preferred system since it does not have the accuracy of the pilot arc or drag technology.
- Blowback: Blow-back is a form of non-touch start that involves the backward movement of the electrode when air pressure is applied to create the arc.
Consumables are parts of a plasma cutter that require replacement after wear due to regular use. They include the nozzle, electrode, retaining cap, shield, and swirl wheel. The main consumables that require frequent replacement are the nozzle and electrode. When buying a plasma cutter, you’ll need to consider the life and cost of replacement of these consumables so that you can be able to determine the cost of operation.
Important tips when using a plasma cutter
- Always wear a welding helmet to prevent slag or any other debris from getting into your eyes. Also, ensure to wear a thick pair of gloves to protect your hands from burns when operating the machine.
- Don’t get too close to the arc. Also, it might get too hot when operating a cutter, so you might need someplace to cool down.
- Ensure the power source can handle the plasma cutter to avoid tripping the breaker or shutting off the power.
- When you have finished using your plasma cutter, always ensure that it is turned off and that there is no metal beneath it. The arc (pilot arc) may take time to cool, which may warp any unattended metal.
Plasma cutting is a relatively straightforward process to learn, and it does not leave much debris compared to oxy-fuel cutters. That said, it is important to choose a plasma cutter that is compatible with your projects to ensure that you’ll not have a hard time performing your projects. Furthermore, it will pay off to compare portability and durability features of different models to ensure that you can use your machine on-demand and hassle-free.
