Best Plasma Cutters of 2021 to add a cherry to your Welding job!

Best Plasma Cutters

Are you looking to buy an effective cutter to cut those metallic sheets and carve out precise shapes for constructional use? Or do you need a metallic cutter for your DIY projects? Well, whatever be your need, you must consider the plasma cutters that are rapidly gaining popularity.

Plasma cutting is the process of cutting through electrically conductive material using ionized gas or plasma. The technique is widely used to cut metals like aluminum, steel, iron, copper, and the like.

The best plasma cutters not only provide precision in cutting but also complete their job much quicker than metal cutters. But with a plethora of plasma cutters available on the internet, it’s difficult to choose the right one.

The varied range of prices also makes buying the plasma cutter a tough choice. That’s why our team of experts has reviewed the best plasma cutters and curated a list of top options out of them.

Why is it important to get the right plasma cutter for yourself?

As basic as the device seems, buying the plasma cutter can be a tough choice. That’s mainly because plasma cutters vary a lot in terms of prices, quality, purpose, and durability.

A plasma cutter’s input voltage determines how thick a metal it can cut while its duty cycle determines its durability. Now the prices of a plasma cutter can vary from $200 to $3000 and further.

Their weights also vary from 20 pounds to 100 pounds and more. So you can understand how differently built cutters will be built for different purposes. Having a cutter that cuts thin sheets well but can’t cut above ¼” thickness isn’t ideal if your work involves cutting thicker sheets.

Similarly, you’d need lighter and more portable cutters for DIY projects. That is the reason why you need to check out the complete guide after reading the review of the best plasma cutters to make a better buying decision.

Buying Guide

Plasma cutters are one of the quickest and most effective tools to cut through sheets of hard metal like iron, steel, aluminum, copper, and so on. The plasma cutter doesn’t cut the metallic sheets through another metal but instead burns through the metal with plasma.

That enhances the precision and detailing while preserving the texture of the metal. But there are a lot of factors you need to consider before buying expensive equipment.

If you’re new to the field and don’t have much of an idea about how to spend on it depending on your usage, we have got you covered. Here we list the most crucial factors that you must weigh in before buying a plasma cutter:

Air Compressor

The plasma air cutters use compressed air to create plasma. Some plasma cutters have inbuilt air compressors, while others need an external compressor to create plasma.

Plasma Cutter gas valve
Plasma Cutter gas valve

Both types provide excellent results, but you need to consider which one suits you. A cutter with a built-in compressor typically suits household and smaller uses. You’d be better off using external compressors in factory locations and construction sites.

Pilot Arc

A pilot arc is a technology that helps cut the metal surface without the cutter getting in contact with it. That not only increases the life of the cutter but also prevents any slags from developing onto the surface of the metal.

It also comes in useful while cutting rusty surfaces, which you typically have to clean before striking. The latest innovation is now available in inexpensive cutters too.

Voltage

Plasma cutters are typically available in 110V, 220V, and dual voltage options. 110V and 115V cutters are ideal for household usage as they don’t need much power. But industrial cutters ideally should have a dual voltage option.

That will help you get enough power for all your needs. You can use the 230V option when you have a generator and need to cut a thick sheet, while the 110V will work for lighter uses and thinner sheets.

Cut Rating

Another crucial factor to consider before buying a plasma cutter is how thick a sheet can your cutter cut. Determine the maximum thickness you need to cut and choose your cutter accordingly.

In case you are unsure of the cutter you’d need for your business, it’s best to go for a high-rated cutter. The A-rated cut is a thickness a cutter can cut at a rate of 10 inches per minute. A severe cut is the maximum thickness a cutter can cut even if it’s at a very slow speed.

Duty Cycle

The duty cycle determines the durability of your plasma cutter. A higher duty cycle means your cutter will be able to last longer. The cycle decreases as you increase the voltage. 

Weight

Plasma cutters vary quite a lot in weight. You will find cutters as light as 20 pounds and as heavy as 100 pounds. You need to decide the purpose of usage while selecting the weight. 

If portability is important to you, choose a lightweight cutter, but typically, heavier cutters are more powerful. So, it all depends upon your usage.

Cutting Torch

Steel Cutting

A longer cutting torch is needed for larger workspaces because it can reach different directions while remaining at the same place. Smaller cutting torches are better for home DIY uses. You should also consider the shape of the handle to avoid any soreness when using it for long hours.

FAQs

Q1. Is it okay to buy cheap plasma cutters?

Plasma cutters are expensive machines, and hence you should choose your cutter wisely. You can buy cheaper plasma cutters if you need to cut something like a 0.25-inch sheet once a week. Otherwise, you should choose a higher-end cutter with better quality, power, and durability.

Q2. Can I Cut Plastic using Plasma Cutter?

A major drawback of plasma cutters is that they can’t cut non-conductive materials. Hence, you can’t cut wood and plastic using such cutters. Moreover, these machines work on the basis of heat, which can damage non-conductive materials.

Q3. When can I use a Plasma Cutter?

You can use a plasma cutter to cut metals to specific lengths, build trailers, cut sections of metals, build custom fences, dismantling metal cars, and more.

Q4. What are the key benefits of a plasma cutter?

Plasma cutters deliver precise metal cutting at a quick speed. They are versatile machines with which you can cut metals of varying thicknesses.

Q5. Why should I buy a quality Plasma Cutter?

Cheap plasma cutters deliver poor efficiency and can break after a few uses. Since it’s costly equipment, you should select one that can last for years and even decades.

Our Top Pick

Miller Electric Plasma Cutter

The Miller Electric Plasma Cutter has a rated output of 140V DC and can even cut metals of thickness ⅝”. That makes it by far the best plasma cutter for industrial use, even though it’s a bit expensive. You might choose from other cost-effective options for household use, but Miller is ideal for industrial use.

Rating- 4.5/5

Final Verdict 

After considering your purpose and costs, you should also factor in the versatility and durability of the machine. It’s not the equipment you’d buy every couple of years. Hence it’s better to forecast for the future and buy a cutter that would last long.
