Plasma Cutter Buying Guide

For some potential buyers of this machine, the best plasma cutter reviews mentioned above may be sufficient in making a final decision. However, for those who are still confused on which product to buy, it is important to read further as this section of the article provides more information that can affect your buying decision.

Electrical Outlet

This factor is, perhaps, the most overlooked variable when shopping for plasma cutters. Keep in mind that an electrical outlet is very important because such device requires adequate deal of power to function effectively. Referring to the reviewed products, most, if not all, of them allow multiple-volt plug applications. Others usually require a 110-volt outlet or a 220-volt outlet. Also, take note of the amperage rating of the model you are buying, considering the electrical outlet’s capability in supporting the minimum amp required by the machine.

It is equally crucial to identify if you are planning on plugging another tool into the same circuit, or otherwise. Each of the devices will surely draw additional power where the other device might take away the power source of the plasma machine. There should be a dedicated circuit for operating the plasma cutter solely.


Although not all operators will be looking for this particular feature, another feature to look for when reading a plasma cutter review is the portability of the machine. If the machine needs to be transported or moved from one place to another, then, portability is a top priority. Nonetheless, most plasma cutters today come in a lightweight and compact size, resulting in maximum portability.

Duty Cycle

Among the important features of plasma cutter is its duty cycle. The max amp output of the machine greatly affects its duty cycle. Hence, more amperage output means more duty cycle. So, it is also crucial to identify how often you are going to use this machine, in order to rely on the max amp output for the max duty cycle. For longer shifts and continuous use, it is sensible to rely on the thickness or thinness of the materials being dealt with. You should look for a plasma cutter model that is compatible to work with the specific thickness of your material. After all, every manufacturer lists the maximum cutting capability of the machine.

Built-in Inverter

While plasma cutter brands with built-in inverters cost more than ordinary models, these machines tend to provide added portability. The high-frequency transistor inverters used in the designs do not only allow for higher switching frequency but also for smaller housing, making the plasma machine more portable. Hence, built-in inverters are perfect for people with mobile services.

Top Accessories

The vast selections of plasma cutting machines come side by side with different accessories. Each of the accessory helps in making the task easier and faster. On that note, here are the top plasma cutter accessories that you may find helpful and suitable for your needs.

  1. Electrodes – electrodes are the elements that create the electrical spark, which turn gas into plasma, although electrodes need replacements frequently.
  1. Consumables – it is the attachment and housing that contain the electrodes while controlling the plasma flow throughout the nozzle. Similar to the electrodes, plasma-cutting consumables wear out too.
  1. Shield Cup – this accessory is attached to the torch handle’s end, controlling the intensity and the cutting force.
  1. Plasma Torch – it is attached to the plasma cutter’s end and the one responsible for controlling the plasma in performing the actual cutting.
  1. Cutting Guides – these accessories help in aligning a cut whether in a straight line or down a predetermined direction.
  1. Silicone Grease – it is used on the O-ring of the plasma torch, helping extend the O-ring’s life because it always faces extreme pressure and heat.
  1. Air Dryer or Regulator – This particular accessory greatly helps in the prevention of moisture buildup.
  1. Cart – while plasma cutters come in lightweight designs, others do not, so a cart comes in handy for the heavy versions, allowing you to move the machine around the work area.
  1. Cutting Table – a cutting table is most important for large materials that are difficult to move.
  1. Circle Cutting Attachment – this makes cutting circles easier, allowing you to simply attach it to the center while the torch swings around in a circular motion at the end of the arm
  1. Hose – the majority of new plasma cutters already comes with a hose, but those without can buy a longer hose for better operation.

Control Panel

Lastly, the control panel is an essential feature of every good plasma cutter. It allows the operator to run the machine easily as it is easy to read, and it also understand controls. Some models also include easy-to-understand indicators throughout the control panel. This feature is most important for the inexperienced operators because of their limited or minimal knowledge in running such machines. For more convenience, you can look for a model with a built-in consumable compartment that is installed on the device’s control panel.

To buy plasma cutter machines, it is important to take note of the above mentioned factors and variables, including the accessories because they are equally essential throughout the buying process. Also, the featured products may be sufficient for a potential buyer to arrive at a final decision because the mentioned brands and models are no less than top-notch quality, high-performance, and excellent efficiency.

While the featured products are not the cheapest options on the market, they are affordable plasma cutter machines with multiple features that are never found in conventional and ordinary counterparts. After all, every consumer gets what he pays for and the same goes with the plasma cutters.

In a nutshell, it is important to make a thorough comparison between the products, and an intelligent selection based on the reviewed products and the considerations mentioned throughout the article. Make sure to eliminate the cost as the basis of your purchase because investing in cheap plasma cutters is not always a bargain if it does not meet your needs.
