How to Choose The Right Plasma Cutter

Since there are so many plasma cutters on the market, it is essential to know how you can choose the right one. In this section, we will consider the critical factors that should affect your choice of a plasma cutter.

How Much Power Do You Need?

Power is a vital factor that ultimately affects the plasma cutter that you choose. For a plasma cutter to cut efficiently and cleanly, it requires power. Almost all plasma cutters use high amounts of power to function.

As can be seen on the market, most plasma cutters are either rated 110 volts or 220 volts input power. This refers to the type of outlet that the plasma cutter will safely work with. A single-voltage plasma cutter works with either a 110 volts or 220 volts power outlet. A dual-voltage unit can use both types of outlets.

Aside from the voltage of the power outlet, another thing that determines the amount of power you need to use a plasma cutter is the amperage rating. For most plasma cutters, the amperage is listed among the specifications.

Therefore, after checking the amperage rating, you must choose a plasma cutter whose minimum amperage rating can be safely and efficiently matched by the electrical outlet to be used.

Another factor that affects power involves the other electrical appliances that will be connected to the same circuit — the more powerful these electrical appliances, the lower the amount of power that enters the plasma cutter. And with lower power comes lower efficiency and functionality.

Types of Plasma Cutters

When we consider the plasma cutters to buy, we need to take into consideration the different types of cutters on the market. They are semi-portable cutters, heavy-duty plasma cutters, and inverter-type cutters.

Let us consider them individually.

Semi-Portable Plasma cutters

As the name implies, these cutters are heavy but not too heavy. They usually weigh around 100 pounds. They have the ability to cut through about 1″ thickness. They are ideal for simple industrial jobs and DIY projects around the home. They aren’t easy to lug around, but they are still reasonably portable.

Heavy-Duty Plasma Cutters

These are, as the name implies, plasma cutters meant for professional, heavy-duty applications. They are often heavy and cannot be carried around conveniently like semi-portable plasma cutters. They are found in industrial settings.

If you are a DIYer, or you are working on a simple project, getting the heavy-duty plasma cutter might be overkill and unnecessary. These tools can cut from between 1″ to 1.5″ thick metal surfaces.

Inverter-Type Plasma Cutter

These are increasingly popular types of plasma cutters. They are more economical as they do not go through consumables as quickly as the other types of plasma cutters. They offer incredible cutting performance, and the plasma flow is easier to regulate. They are easy to clean and maintain.

What is Duty Cycle?​

In your quest to find the right plasma cutter, you might see plasma cutters with a “duty cycle” specification. Duty cycle refers to the length of time you can safely weld non-stop at maximum amperage. It is the fraction of an hour in which you can safely use the plasma cutter.

On any plasma cutters, this value is represented in a percentage. The main factors that affect the duty cycle are the amount of amperage drawn by the unit. If the plasma cutter has a 50A rating with a 50% duty cycle, this means that it can run non-stop for 30 minutes in an hour without overheating.

The larger the amount of power the plasma cutter requires, the higher the duty cycle that it has.

What Are Consumables?

In welding, choosing the right consumables is vital to the success of your project. Consumables, as the name implies, are the parts of the plasma cutter that are “consumed” during use. In most cases, the electrode and the nozzle are the most “consumed” parts of every plasma cutting system.

Therefore, depending on your method of welding or your usage patterns, you will need to replace these parts quite often. In an ideal world, you shouldn’t replace them, but alas, we can’t always get what we want.

Consumables can make your “bargain” plasma cutter expensive. As you use the cutter, you will need to replace them and over time, the total cost of consumables bought will dwarf the price you bought the plasma cutter itself.

Aside from the electrode and the nozzle, other consumables include the swirl ring, the inner retaining cap, the outer retaining cap, and the shield.

If you desire to maintain consistent and high performance, you need to keep an eye on these consumables.

What Other Equipment Will You Need?

Most high-quality plasma cutters come with all the equipment you need. The only thing they often lack is pressurized air. One of the most important things to ensure your plasma cutters work efficiently is air.

Airflow is essential to plasma cutters. The industry standard is supplied oxygen because it provides the best, cut quality, and fastest speed. However, don’t use oxygen plasma gas to cut aluminum or stainless plate.

With clean pressurized air, the accuracy and overall performance of the plasma cutter are improved. Aside from the better performance, using air eases the stress on your consumables, making them last longer and saving you money.

If you find a plasma cutter that comes with pressurized air, that is fine. A growing majority of quality plasma cutters come with their air compressor. However, most of them still rely on shop air.

Desiccant Air Dryer & Filtration Systems

A desiccant filter system ensures that clean air feeds through the nozzles. Why is this important? Well, some of the significant agents that damage your plasma cutter or reduce its efficiency are oil, dust, debris, and moisture. By using a filtration system, you can significantly reduce the chances of these agents entering your plasma cutter.

The desiccant filter system removes moisture and dirt from the air entering the nozzles even before it enters the torch. A filtration system might be expensive, but in the end, it saves you a lot of money. Since the air is pure, the rate at which you go through consumables is highly reduced.

It also makes your cuts cleaner and ensures an overall better performance.


What is the best plasma cutter under $500?

My top-rated plasma cutter under $500 is the Lotos LTP5000D. It ticks so many boxes that make it is a great budget option. It is easy to set up and start using, is durable after many years of use, can be carried around with ease, and importantly, delivers excellent cutting performance.

What Other Equipment Will You Need with a Plasma Cutter?

Most of the plasma cutters come with almost all the essential parts you need. However, you need a high-quality air compressor, sufficient ventilation, and a top-of-the-line filtration system.

How do I choose a plasma cutter?

Choosing the right plasma cutter is no simple task. However, the main things to keep in mind when shopping for one include your budget, the power required, the specific purpose of the cutter, your skill and expertise, and your performance requirements.

How much does a plasma cutter cost?

Plasma cutters are expensive tools. The higher the amps, typically the higher the cost. However, not all of them are priced that way. Entry-level cutters cost as little as $220 and still offer decent performance. However, if you are looking for a plasma cutter that can cut through 1″ or more, you might have to shell out over $1500.

What kind of gas do plasma cutters use?

Different types of gases are used in plasma cutters. Some cutters use Argon gas. Others use a mix of Argon and Hydrogen, while other mix hydrogen and nitrogen gas.

What are the most economical plasma and shielding gas?

The most economical gas for plasma cutting is widely regarded to be clean, dry shop air

What air pressure is required for plasma cutting?

The air pressure for plasma cutting is usually set around 60 psi.

Can you use nitrogen with a plasma cutter?

Nitrogen gas is often used for plasma cutters and systems that can cut up to 3″ thick metal surfaces.

What is f5 plasma gas?

F5 plasma gas is the code name for a mixture of nitrogen and hydrogen gas. It is in the ratio of 95% nitrogen to 5% hydrogen.

How do you cut aluminum with plasma?

Some believe that Aluminum can’t be cut with plasma because the material can’t withstand the heat. However, using the right combination of gases, you can efficiently cut Aluminum with plasma. When cutting Aluminum, use a high-amperage plasma system and a mixture of argon and helium gas.

How a Plasma Cutter Really Works – Visite NC

Monday 27th of April 2020

[…] Plasma cutting torches generally make use of a copper nozzle to tighten the gas stream with the arc moving through it. That arc jumps from an electrode in the lantern to something else– typically the conductive material being cut. That’s a ‘moved arc’. There are some systems that make use of a ‘non-transferred’ arc where it leaps from the electrode back to the nozzle, but those are not normally made use of for reducing. To make sure that indicates that plasma cutting is only utilized for materials that are conductive, primarily light steel, stainless steel, and also lightweight aluminum. However great deals of various other steels and also alloys are conductive too, such as copper, brass, titanium, Monel, Inconel, cast iron, and so on. The issue is that the melting temperature level of some of those steels makes them challenging to reduce with a good quality edge. […]
