So it’s finally time to buy that new plasma cutter! Plasma cutter reviews is a great place to start.  We’ve done all the work and scrapped the internet searching for the best cutters.

Once you get one you’re going to wonder how you ever lived without it. Cutting metal will never be the same, and honestly it’s also a lot of fun. Now before we get to the specs and the reviews,we need to understand what we’re looking for and how to make sure that’s what you need for your shop.
Right below here, you’ll see a quick chart I put up if you’re in a hurry. These are the top-selling brands with the best reviews from amazon. You can go there and get an idea of what’s available and whats specs are on the plasma cutter. The entire specs sheets will be thoroughly gone over, so you know what to look for when reading the plasma cutter reviews.

Why do you need one?

What is plasma cutting? A plasma cutter is a very handy tool to have in the shop. Cutting metal is not easy to do, and obviously you need some hard-core machines to do it. The nice thing about a plasma cutter is, its small enough to haul around and you won’t really have to hook up all the extra’s to get it to work.

A plasma cutter serves many needs in a shop, fabricators use this tool everyday. Artist use this to create art by cutting metal and welding them together. If you need to cut steel or many other hard metals, this is the tool you need! Plus it’s portable and it’s cheaper than using Oxyacetylene.

What makes a good cutter?

If you read some of the Plasma cutter reviews, a key factor mentioned is How thick of metal can it cut through.  If its a good one will be able to cut through hard metal without a problem. The size of the metal that it can cut will make a good cutter as well. Can it cut through 1/2″-3/4″ steel, and how fast and accurate can it do that?

Price is another factor, do you get what you pay for? Maybe. I know tons of happy people who paid $425 for a good one, and they are completely happy. I also have a bud, who paid big bucks for his over $1400. And that’s great too, he uses his in his auto garage daily, loves it!plasma cutter reviews[ ATTRIBUTE: Please check: http://www.flickr.com/photos/36189452@N00/4651760215 to find out how to attribute this image ]

Things to look for, and I’ll go through each down below.

  1. Voltage/Frequency – Power supply 110 or 220v
  2. Transistors
  3. Cooling System
  4. Max Cutting Thickness
  5. Arc
  6. Torch
  7. Compressor

So let’s take a look at some of the features that come with a cutter.

Automatic Dual Voltage / Dual Frequency

Depending on which machine you choose, you may have to configure the wiring. What this means, is your machine can be wired for 110 or 220v. But your shop or garage at your home might not be wired for 220v. So, keep that in mind. But most machines will come with 110 or 220 and you will have to screw the wires into the body of the cutter. Or the machine might be screw in, a nice and easy way to go. Pretty easy. But some machines come wired to 220v right off the bat, they may come with the 220 to 110 adapter and you can just plug right in a go. Look for a multi-voltage plug (MVP) to be safe if you’re not sure.

A dual meter in the front of the machine will allow you to adjust to the proper amps if whether you’re using 110 or 220v.

Transistors

Insulated Gate Bipolar Transistor (IGBT) plasma cutting technology

Metal Oxide Semi-conductor Field Effect Transistor (MOSFET)

Plasma cutting machines will have either, the IGBT or MOSFET transistor. I have read several forums of people discussing the pros and cons of both types of transistors. And what I can gather from that is, depending on how hard you’re going to use your machines, the transistor can make the difference. Here is the short of it:

If you are using your machine a few times a week, than MOSFET will be good.

If you plan on using your machine more than that, IGBT has been known to hand the amp & temperature requirements of higher amp plasma cutters.

Cooling Systems

Built in cooling system for the machine are essential for the machine to work and the overall longevity.

Max Cutting Thickness

This is a really important feature to not overlook when reading the reviews. Make sure the machine is able to cut your desired thickness. If not, you could be in trouble and not be able to cut all the way through that piece of steel.

The machines will defiantly list the Max Cutting Thickness and the Max Severance Thickness. It might look like this

Max Severance Thickness 3/4″

Max Cutting Thickness 1/2″

The max cutting thickness you need is up to you, and it will be the difference in money when you purchase. Possibly $100 for more max thickness. So, be sure to know what you’re going to be cutting before you start looking.

Arc

The torch holds the consumable electrode in a chamber where gas heats up to form plasma. The tip of the torch holds the constricting nozzle with an opening for the arc and plasma to pass through. As the arc and gas pass through the opening it forms into a more constricted and focused column that increases the velocity and heat of the arc.

Consumables, machines come with starter sets, but you’ll want to grab some extras just to have in stock.

Torch

Your new machines will come with a new torch as well. Some torches are customized for your fitting. The torch trigger can moved to your liking. It can be used in thumb and finger positions. Torch heads are usually low profile for tight spaces.

Compressor

They run on compressed air. So you will need to add a compressor with around 70 psi and the machines will run beautifully. If you don’t have a compressor, you can pick one up for under $75.

As we add more reviews they will be added here. Check back often for reviews. If there is a machine you want us to review, let us know. Or just leave a comment about your machine, we’d love to hear from you.
