Not only are plasma cutters cool in theory, they are also useful tools in the workshop especially if you deal with a lot of metal cutting in your day to day work as a professional or hobbyist metal worker.

Plasma cutters are tools that use inert gas blown at high speeds out of a nozzle. They are equipped with an electric arc that when applied to gas, turns into the fourth state of matter called plasma.

Even though they sound like cutting machines from the distant future, plasma cutters are used in the present day to cut through different types and widths of metal easily, accurately and taking less time than traditional methods.

Plasma Cutter Buying Guide

Before we dive into the different features that you should watch out for, it would be in the interest of beginners to familiarize themselves with the vital parts that make up a typical plasma cutter.

How Plasma Cutters Work

Basically, you can understand how a plasma cutter works by understanding just three parts:

Of course, like any other power tool, a plasma cutter works through a power supply which converts single or three phase AC line voltage into a DC voltage which ranges from 200 to 400 VDC.

The DC voltage is the one that maintains the plasma all throughout the cut. In relation, the arc starting console or ASC is the circuit which produces the AC voltage which sparks inside the torch, thus creating the plasma arc.

Last, is the plasma torch, the part that provides proper alignment and cooling of main consumable parts such as the nozzle, electrode and swirl ring required for the generation of the plasma arc. To help you visualize these, here is an illustration from LincolnElectric.com

If you’re still a bit confused, this video from Cruxweld’s YouTube channel should clear things up.

Seeing how a plasma cutter is used might also be helpful for beginners. If you want to see a demonstration, check out this video by Weld.com on YouTube.

Now that that’s all a little clearer, let’s discuss the things you need to consider when scouting around for the best plasma cutter for your needs.

Plasma Cutter Duty Cycle

The first thing worth checking out is a plasma cutter’s duty cycle or the period of time that it takes a signal to complete an on and off cycle. This is expressed as a percentage or ratio.

If you’re planning on using your cutter for short bursts rather than long periods of time, you’ll want to buy one with a high amperage output. This means that it will have more duty cycle.

However, if you want a plasma cutter that you can use for long periods at a time, the thing you should consider is the thickness of metal that cutter will be capable of. If a plasma cutter is designed to cut thick metal then it should be able to run for extended periods.

The Cutting Speed

Another important factor that will affect your buying decision is the cutting speed.There are usually three options available when it comes to the quality of cuts:

The rated cut will give you the best quality of cut which is smooth and clean. This is normally used to cut steel that is not that thick and at maximum speed.

Meanwhile, quality cuts will also give cuts of a decent quality, but with thicker materials and taking a longer time.

As the name implies, the severe cut option is used for materials of great thickness. This option will give the user less fine cuts which may need refining afterwards.

Plasma Cutter Starts

The type of start a plasma cutter is equipped with is another thing to consider. The start is the one that initiates pilot arc. There are two types:

Plasma cutters with contact starts are recommended for users who plan on using their cutter

around appliances like computers, televisions and other electronics as they will not interfere with the plasma cutter like the high frequency start will.

The Control Panel

Having a user-friendly control panel is an advantage for beginners who want to improve their plasma cutting skills. You should choose a plasma cutter equipped with easy-to-read and easily understandable controls and indicators.

Inverters And Plasma Cutter Portability

The last three factors in choosing the best plasma cutter for your needs are all to do with your portability needs. If you plan on using your plasma cutter in remote sites far from or without power outlets, you might want to check out cutters with built-in inverters.

Having these inverters enables cutters to take DC power and feed the power through a high frequency transistor-inverter. One catch though is that these plasma cutters usually fetch for a much higher price that those without.

As mentioned earlier, plasma cutters use air to operate, thus it is important to find out what type of air supply cutters have. While most cutters use regular air, some are equipped with bottled nitrogen which is less expensive and believed to produce lesser oxidation.

If portability and weight are issues for you, you might want to consider a plasma cutter with a built-in air compressor as they make cutters lighter. However, be warned that these cutters should only be used to cut thinner materials.

Plasma Cutter Safety

Here are a few reminders and guidelines on safety gear and measures to help avoid accidents.  Cutting metal may look cool but it can also be very dangerous with sparks and metal pieces flying off.

To avoid burns and other injuries, you should consider wearing some or all of the following gear as recommended by actual people who use plasma cutters for work:

It is also a great idea to have a functioning fire extinguisher around your worksite in case of things catching fire from sparks.
