Plasma cutters are designed to cut thick and tough metals and are best suited for machine shop and heavy construction applications. They are heated quickly with compressed air or gas, and the arc torch can reach extremely hot temperatures. Then, the small flame can easily make clean cuts on tough metal and steel. If your job is difficult and you need a high-quality plasma cutting machine, please consider using one of the following machines for your workshop.

Our reviews are driven by hands-on testing by actual buyers, expert opinions, "popular wisdom" evaluations, and our own expertise. We always strive to provide true and accurate guides to help you find the best choice.

Traditional plasma cutting machines use air, oxygen or nitrogen for cutting. They are more affordable than high-definition plasma cutting machines and can perform high-quality cuts. However, the cutting surface will have an angle. The ratio of the minimum hole mass to the plate thickness is 3:1. Most conventional plasma cutting machines have operating currents ranging from 65 amps to 200 amps. They are mainly used for cutting mild steel. Traditional plasma cutting machines are usually used in home garage manufacturing to medium-sized production. They are ideal for simple cuts or cuts that do not require complex edges.

High-definition plasma cutting machines are very useful in situations where more complex cutting is required or edge quality is of concern. They use mixed gas and have smaller nozzles. The nozzle helps tighten the plasma stream, allowing you to cut parts more finely. A gas in the mixture acts as a shield and covers the plasma stream, making it straighter. Since the high-definition plasma cutting machine has a more directional flow, it will not produce consolidated slag during cutting. This eliminates grounding and gouging. High-definition plasma cutting machine is very suitable for more demanding applications. It has a higher duty cycle and can run 24 hours a day.

This is the preferred brand for cutting tools and welding machines. It is headquartered in Sunnyvale, California and has been operating since 2007. In order to provide a consistent and accurate current to the cut surface, Lotos uses the latest technology, such as MOSFET-based high-frequency inverter technology. If you are looking for a plasma cutting machine, we recommend Lotos CT520D 50 AMP pneumatic plasma cutting machine.

Amico was founded in 1995 and produces affordable welding and cutting machines. The company continues to expand its product line to meet new consumer demands. Its cutting machine uses different technologies and can easily achieve clean cuts on different surfaces from aluminum to stainless steel. The Amico CUT-50 plasma cutting machine is one of the company's best products.

The company was founded in 1917 and has been designing and improving its welding and cutting products for decades. All its products can be used in industrial environments and provide 5/3/1 industrial warranty. Whether you are a farmer or a DIY enthusiast, this company has products for you. We like the Hobart 500565 Airforce 27i plasma cutting machine.

This is a very important feature. The thickness of the metal usually determines the cutting speed. Before you get a plasma cutting machine, it is important to compare the cutting speed to the metal thickness. The cutting standards are divided into three types: quality cutting, rated cutting and heavy cutting. Knives with high-quality cutting grades can take a while to cut thicker materials. A type with rated cutting grade to cut medium-thick steel at the best cutting speed. Plasma cutters with severe cut grades can slowly cut very thick materials. 

This is another important feature to consider. The amperage usually determines the duty cycle of the plasma cutting machine. For example, a plasma cutter with a high current output will have a better duty cycle than a plasma cutter with a low current output. If you want a plasma cutting machine that can be used continuously for a long time, please buy one according to the thickness of the material you usually handle. Also check the maximum cut thickness. 

In order to work efficiently, a plasma cutting machine requires a lot of electricity. They are usually designed to be powered from 110 volt or 220 volt power outlets. Each cutting machine has a rated current. Check the voltage of the power outlet to be used to ensure that it can meet the minimum amperage requirements of the plasma cutting machine. It is also important to equip your plasma cutting machine with different circuits, because when other machines are connected to the same circuit, the input power of your machine will be reduced.

Most handheld plasma cutting machines use air during the cutting process. Some professionals use bottled nitrogen for cutting because it is cheaper than bottled air. They also believe that nitrogen is drier than compressed air and therefore produces less oxidation. Some cutting machines have built-in air compressors, which means you don't have to carry bottled gas with you.

More on cleaning and details

In order to break into the field of plasma cutting, Lotus has been building affordable and high-performance machines. This reasonably priced machine continues this tradition by offering 50 amps and a 60% duty cycle. We like the pilot arc function, which allows you to cut without attaching the tip to the metal. Lotos LTP5000D uses harmless compressed air. It can cut a variety of materials, including aluminum, copper, low carbon steel, alloy steel and stainless steel.

This is one of the best plasma cutting machines in the 110V/220V range. It can cut rusty, painted and rough surfaces with minimal dross. The cutting range is 10-50 amps, and it can perform 1/2-inch clean cuts and 3/4-inch maximum cuts under 220/240V. PAPST's advanced cooling technology ensures stable performance. The plasma cutting machine also has a pre-installed air filter regulator and D-type plug. 

Lotos LTP5000D is ideal for DIY work or light cutting projects. It weighs less than 20 pounds, so it is not too difficult to carry it with you. However, it has some disadvantages. First, slag may accumulate on the tip of the tool, causing it to slow down or stop. Second, the compressed air pipeline is very small.

Plasma cutters are designed to cut conductive materials. These machines are highly efficient and can cut all kinds of metals. Zeny DC inverter plasma cutting machine can cut materials as strong as alloy steel. Its high-quality plasma cutting torch is designed to enhance and improve cutting quality. The machine has a built-in inverter, which can generate a powerful DC welding current.

If you need a dual-voltage DC plasma cutting machine, then this machine is worthy of attention. It can work at 110 volts or 220 volts. It can also supply air in advance and automatically shut down when the air distribution is delayed. This plasma cutting machine is suitable for a variety of applications, including automotive pipe work, light industrial work, sheet metal manufacturing, and repair and maintenance services. The device is very portable because it weighs only 24 pounds. It has a handle to improve portability. We also like the arc ignition system, which can be started easily.

However, this plasma cutting machine has some disadvantages. Zeny provides complex instructions that are difficult to understand. The design of the air conditioner is not very good, and it may affect the power of the arc.

This plasma cutting machine impressed us not only its price, but also its so many powerful features. It automatically adapts to input power from 100V to 240V, and its torch design ensures a clean cut every time. Its handle is made of heat-resistant and impact-resistant materials. The machine is designed for demanding construction or industrial projects, but it can also be used at home. 

CUT-50, 50-Amp Pro from Amico. The plasma cutting machine can cut stainless steel, copper, aluminum, low carbon steel, alloy steel and other materials. It can cut metal up to one inch thick. Amico recently upgraded this model, so it now has gauges and regulators on the front, and the filter is inside it. Its new design makes it easier to use. The 50-amp plasma cutting machine also has an inverter for high-frequency start. You don't have to place the tip of the torch on the metal to cut. This plasma cutting machine has an instrument that allows you to read and control the temperature more effectively. 

Unfortunately, it is heavy (31 lbs), so you may not be able to carry it easily. It is not very durable either.

Hypertherm is a unique company because it only sells cutting technology. Unlike other companies for the products we listed, it does not manufacture welding machines. It specializes in plasma cutting machines, laser cutting machines and water jets. Since 1968, Hypertherm has been manufacturing high-quality plasma cutting machines, most of which are very popular. 

Hypertherm 088079 Powermax30 XP is one of the best household cutting machines, with all the functions a DIYer might need and more. Although the machine cannot perform engraving like the Powermax 45XP, it can easily cut 5/8 inch metal plates and give the cut surface original edges. The cutting machine has a 110V/240V power input and uses nitrogen or air to cut conductive metals such as aluminum and stainless steel. We also like the 15-inch torch cable, which makes the plasma cutting experience better. Drag cutting technology makes tracking easy and ensures that double arcs do not occur. We are very impressed with this plasma cutting machine. The design of the flashlight provides a comfortable grip, and it is made of heat-resistant and impact-resistant materials. 

One disadvantage is that if it is used in large quantities in an industrial environment, the internal air valve of the machine may leak. Unlike some top plasma cutting machines, it does not have a CPC port for computer control.

If you are looking for a high-quality plasma cutting machine and have a limited budget, then this one is worth considering. With the continuous advancement of plasma technology, many companies continue to improve their processes to produce better and more affordable machines. Forney's Easy Weld cutting machine is a good example of this endeavor. It is well made and cut very well. If you use it to cut any metal of 1/4 inch or smaller, it can cut it almost effortlessly. 

We really like the size of the flashlight and the clamp wire, because it is enough for most people. If you want to add variety to this welder, you can get extensions that are sold separately. This machine adopts high-frequency starting arc ignition, which is convenient to use. Drag Torch Technology creates smooth, precise cuts because you can drag the tip on the metal surface. The Forney Easy Weld cutter is a good choice for experienced operators who cut 1/4 inch metal on a regular basis. Metals that are usually this thick include galvanized steel, stainless steel, copper, and brass.  

However, although this machine can cut painted or rusted metal, it does not cut well. It is also extremely limited by its 110V/120V input and 20 amp output, and it is difficult to cut any metal larger than 1/4 inch. If you don't cut any thicker metal, this is a good choice.

The Hobart 500566 Airforce 40i plasma cutting machine is an impressive machine and good value for money. It has a 50% duty cycle and can cut 7/8 inch mild steel. It can also cut 3/4 inches at a speed of 6 inches per minute. Its maximum output power is 40 amps. 

The machine uses Hobart's wind tunnel technology to help prevent internal components from being damaged during the cutting phase. However, it is not ideal for amateurs, because it is designed for larger cutting rather than fine work. What we like most about it is that you can use it without having to check the instructions every time.

The Hobart 500566 Airforce 40i plasma cutting machine is one of the most expensive models manufactured by Hobart, but we like its performance. It can cut metal effortlessly, allowing you to spend less time on projects. The plasma cutting machine is an upgraded version of the 700i cutting machine. It has a redesigned flashlight and an ergonomic handle, which is very comfortable to use for a long time. The incision made by it is very clean and the incision is very narrow. Minimal cleanup is required. The arc start function is great. When you take off and lose the arc, automatic re-ignition technology will come in handy. If there are any major problems, the built-in diagnostic system will alert you. The machine has an on-demand fan and thermal overload protection. 

But we don't like the ground clamp because it doesn't have a good grip. In addition, the power cord is not very long, if you work in a large area, it will greatly limit your work.

Anyone who has ever been in contact with metal will tell you that precision cutting with traditional metal knives is no joke. Poor tailoring can affect the appearance of the final product, especially the finish and fit. If your job involves cutting steel plates of different sizes and shapes, please buy Lotos LTPDC2000D. It is a three-in-one cutting machine and can also be used as a bar welder or TIG welder. 

Its pilot arc welding torch can quickly cut painted, rusty and rough surfaces with minimal dross. It improves accuracy and reduces material waste. Automatic dual voltage allows Lotos LTPDC2000D to directly turn on 110V/120V under 50/60 Hz power supply. 

The tool has an excellent safety feature. It can use machine compressed air, which means you don't have to carry pre-compressed air in the cylinder. It can make clean cuts on 1/2 inch thick metal. The maximum cutting thickness is 3/4 inch. Pilot Arc Technology allows you to cut metal without touching the torch tip to the metal. The cutter comes with a 30-day money-back guarantee and a one-year limited warranty. You can buy with confidence. 

However, the guide is not well constructed and slides on the cup. If you are a novice, you may find it difficult to maintain a distance, and you may end up damaging the nozzle and electrode. In addition, the consumables of the machine are specific and not cheap

Everlast designed​​PowerPlasma 62i to replace PowerPlasma 60S. It has a BlowBack pilot arc function, which can be used more easily for rusty and painted materials. You will also like its super bright control display, even if you are wearing safety gear and the environment is full of bright light, these displays are easy to read. In this price range, it is difficult for you to find a plasma cutting machine with the same functions. It has a 60% duty cycle at 60 amps.

Everlast includes automatic pressure setting in this cutting machine. It can adjust the pressure during the cutting process to achieve a clean cut. If there is no cutting after the three-second arc time, the three-second tip timer will quickly shut down the torch. This new model has gouging functions for removing old welds and metal defects. This feature is unusual for a cutting machine at this price. You will be satisfied with the digital arc control, which helps maintain the optimal cutting temperature for clean cutting. 

However, there is a problem with the power of this machine. If you want to use a generator to power this cutting machine, you need a generator that can generate at least 11,000 watts of clean electricity. If you do not do this and the machine is damaged, the warranty will be invalidated. But it is not easy to obtain generators that generate so much clean electricity. The machine is also very heavy and not very portable.

Answer: You need a reliable and powerful air compressor and air hose to ensure the normal operation of the plasma cutting machine. Many may not be equipped with an air hose plug, so you need to contact the manufacturer before purchasing a plasma cutter.

Answer: Since it is made for cutting thick steel and metal, the pilot arc can reach extremely dangerous temperatures. Be careful when handling plasma cutting machines, as their temperature can be as high as 45,000 degrees Fahrenheit.

Answer: It depends on what and how you want to cut. If you only need to cut one piece, it should not take more than a few seconds. If you want to make small precise cuts, it may take a few minutes. Always work slowly and methodically to make sure you stay safe.

For one of the most powerful and precise plasma cutting machines, consider the Lotos 50Amp non-contact guided arc plasma cutting machine. 

You can get Zeny DC inverter plasma cutting machine, which provides clean and smooth cutting at a cheaper price.
