10 Best Plasma Cutters Reviewed & Tested

For years, metalworkers have had to use saws and drills to shape metal, and they had to contend with the slow speeds and inaccuracies of the tools. As a result metal work was tedious and expensive as the saws and drills quickly wore out. However, with the progression of plasma cutter technology, it is now easier to make clean, smooth cuts, unlike before when one had to up with a jagged mess that needed clean up time.

Our Top 3 Picks

[srpshortcode id=”20201″][/srpshortcode][srpshortcode id=”20202″][/srpshortcode][srpshortcode id=”20203″][/srpshortcode]

A plasma cutter uses a jet of hot plasma to cut through electrically conductive material and sit results in better cuts as there is no physical contact. Other than higher quality cuts below are some more advantages of a plasma cutter.

Versatility – First, you can cut through many metals using a plasma cutter, and you can also get through material of varying thickness with ease. The power of the device will determine how fast you can get through a metal, but it shouldn’t be an issue.

Portability and ease of use – Gone are the days when you had to deal with a large plasma cutter. Now, these units are smaller and lighter but with the power and performance of larger units. Moreover, they are ergonomically designed with handles, and you can also purchase wheel kits for transportability. As for ease of use, they have a simple learning curve, and no complicated adjustments are required to make intricate

Accuracy – Precision is indispensable when cutting through any metal. Plasma cutters are incredibly precise, especially where cutting measurements are made in advance. We suggest you invest in a cutting guide for better results.

Speed – Finally, plasma cutters are fast and get through any metal with ease; like a hot knife through butter. The power of the unit determines the speed, but there are potent cutters available today.

Given the many tools available today, making a decision can be daunting. Our mission at Contractor Culture is to ensure that you get the best units at the most affordable prices. We have provided our top picks, but first a buying guide.

Selection Criteria

What is the thickness of the metal you will most frequently cut?

Every metalworker has this one metal thickness that they frequently work with, and one should invest in a plasma cutter that is best suited for that width. ¼” metals require low amperage about 25 amps, unlike ½” metals that need between 50 and 60 amps. ¾” to 1” thick metals will need a plasma cutter that can get to 80 amps.

Though you can use a smaller machine to cut through thicker metal, the results will not be as pleasant, and you will need to clean up. There is even a possibility of it not making it through the plate.

Cutting speed

The work environment often influences the tempo. If you are in production, you want a unit that can get through most materials with ease. It is best practice you invest in a tool that can accommodate twice your normal cutting speed. However, if you are a DIYer, and speed isn’t a concern, buy a plasma cutter for your standard thickness.

Always consider the IPM (inches per minute) and the amperage.

Duty Cycle

Duty cycle is measured as a percentage of 10 minutes, and is the number of minutes you can cut at a particular amperage without overheating. If a plasma cutter has a 50% duty cycle at 60 amps, it means you can use it continuously cut for 5 minutes without at 60 amps without needing a break.

If you desire to work for extended periods, uninterrupted, we recommend a tool with higher duty cycle.

Alternatives to High-Frequency Starting

A pilot arc, which features on most plasma cutters utilizes high frequency to conduct electricity. However, this frequency often interrupts equipment that may be in use in the area, and thus you want a unit that eliminates the problem especially in sensitive areas.

We recommend a lift arc which uses a DC- electrode, and a DC+ nozzle. The two initially touch, so that current flows through the two, but the electrode eventually pulls away establishing a pilot arc.


What is plasma?

One common question among plasma cutter enthusiast is what plasma is? Well, this is the fourth state of matter that exists when gas is ionized and thus capable of conducting electricity.

A plasma beam is capable of producing heat up to 22,000 degrees Celsius and therefore excellent at cutting materials that conduct electricity.

Can one cut underwater?

Yes. However, expect reduced cutting speed and quality owing to water’s cooling effects. However, ensure you keep water levels at about 1-inch for the smoke absorption properties of water, and you maintain the cut quality at this depth.

What are consumables?

Consumables are the parts of the pcutter that wear out due to use. Often, these are the nozzle and the electrode. A plasma cutter can reach temperatures up to 22,000 degrees Celsius, enough to melt any metal. However, the nozzle is copper thanks to its superior heat transfer but melts at 1,100 degrees Fahrenheit. Compressed air creates a barrier between the plasma and the nozzle to reduce wear and tear, but it is inevitable, and they eventually need replacing.

The electrode, on the other hand, is hafnium as it is efficient at emitting electrodes but they will eventually evaporate. Consumables need to be replaced otherwise the torch will misfire and ruin the quality of your cuts.

Consider consumables when purchasing plasma cutter as they might influence the cost in the long run. A low-cost unit but requires constant consumable replacement will be expensive than a pricey piece of equipment with efficient use of consumables.


Most plasma cutters are ready to use but often need pressurized air. Ensure you check the manufacturer’s recommendations and exceed them if you want cleaner cuts. Most of the units on this list are great for DIY aficionados and professionals. Remember to stay within your budget though we would recommend the pricier units owing to their quality and use of consumables.

You can get most of these plasma cutters from local dealers, but we recommend Amazon as you can view reviews and get discounts. Thanks for coming this far, and please leave your thoughts in the comments below.
