How To Pick The Best Plasma Cutter: Buying Guide

Plasma cutters are an efficient way to cut through metal sheets and aluminum with precision because they burn through the metal with plasma. With so many specifications and features of the plasma cutter in the market today, it can be tedious work trying to pick the best plasma cutter.

  • Air compressor

Your needs are a priority when picking one of the best plasma cutters. When choosing a plasma cutter, you want a top-notch machine. Your need for a plasma cutter to manage smaller jobs will make you choose one with a built-in air compressor. The air compressor is what creates the plasma. It could be an external supply in contrast to the built-in air compressor. They both work well, choose that which is convenient for you.

  • Pilot Arc

The latest brands and developments on the plasma cutter have featured a pilot arc. The pilot arc aids cutting without the tip of the torch striking the metal. It provides a stable cutting arc. However, this is not present in all plasma cutters. For convenience pick the plasma cutter with a pilot arc. However, plasma cutters without the pilot arc feature are relatively cheaper.

  • Thickness of Metal

An important thing to note when picking one of the best plasma cutters is the thickness of the metal sheet that a plasma cutter can cut through. Only go for a machine that can cut through the maximum thickness you might have to cut through.

You’ll need a plasma cutter that can work productively for longer hours without overheating. Time will be wasted if you have to wait on a machine to cool off now and then. Therefore, consider the duty cycle of the plasma cutter before purchase.

  • Voltage

The available voltage option is another point to note when picking the best plasma cutter. There are three voltage types: 120V, 240V, or a dual voltage. The 120V, being the smallest, it’s particularly useful for beginners and low scale cuttings say at home. The 240V would require a generator as opposed to the 120V that can be used in a standard power outlet. A plasma cutter with a dual voltage option would give you the luxury of switching between the plugs of both 120V and 240V.

  • Portability

For portability, the weight of the machine matters. Its torch is an important aspect too. If your job requires constant mobility from one location to another, you might want to consider a light weighed plasma cutter. However, the heavier the machine, the more work it gets done. A lighter machine would not cut through a metal sheet as thick as a heavier machine would.

  • Length of Torch

Consider the length of the torch too. A short torch in a large workspace would give unnecessary stress with moving the heavy machine here and there. With a longer torch, you can work in different areas of your spacious workspace without carrying the plasma cutter around.

  • Cost

Finally, Note the cost and make sure it penny counts. The cost of purchase, maintenance, and operation. An expensive plasma cutter should have your desired features, quality, and merits. Plasma cutters with lower operating costs are great investments since the consumption rate is low: this saves you money.

How Does A Plasma Cutter Work

A plasma cutter works by sending an electric arc through a gas: oxygen, nitrogen, or argon. This gas passes through a sheet of metal or stainless steel to cut it open. The electric arc elevates the temperature of the gas to a state called the plasma, whose electrical conductivity is transfer to the metal to be cut. The nozzle through which the cutting gas passes is narrow, hence an increase in the speed of the passing air. This high-speed gas cuts through the molten metal sheet to create the designed opening. 

As a recent innovation, there is a pilot arc between the nozzle and the electrode that ionizes the gas to generate plasma before the arc transfer.

In simpler terms, a plasma cutter works by directing plasma through the creation of a circuit from the electrode to the metal sheet. The process of plasma cutting works only on electrically conductive materials using hot plasma.

How To Use A Plasma Cutter

A plasma cutter requires a petty level of technical skills. It is easy to operate. Having a suitable workspace and table or grate is relevant. This is to check for first before working. It allows for freedom of movement while cutting the metal. Ensure that the plasma cutter is plug into a power source. Check the built-in air compressor or attach the external one to avoid a decrease in the pressure of the gas while in the middle of work. Have I mentioned that a ground clamp is necessary? Attach the ground clamp and then turn on the plasma cutter.

Now, the plasma cutter is ready to be used. Select a desirable current where options are available. Be sure to keep the plasma cutter close enough to the metal while you activate the device using its trigger. All safety measures must be put in place to protect yourself from harm and hazards. Also, turn off the machine, disengage all extensions, wind up the hoses, and keep the machine in a safe place after use.

FAQs

  • How much is a plasma cutter?

The price of a plasma cutter depends on its type, size, and features. However, you can get a plasma cutter for as low as $500 and as high as $15,000

  • Plasma Cutting Vs Laser Cutting Difference

Plasma cutting differs from laser cutting in so many. A first and obvious difference is that plasma cutting works on all kinds of metal material whereas laser cutting has a wider range of cutting materials application, which includes glass, ceramic, non-metals, and metals alike. 

Aside from that, laser cutting has a more obvious advantage over plasma cutting in terms of thin sheet cutting. It also has higher precision, brightness, direction, and intensity. With the laser cutter, there is almost no thermal deformation of the workpiece, but its plate thickness is limited.

The cut made by the laser cutter is narrow and neater when compared with the plasma cutter. Though the plasma cutter is cheaper, the laser cutter has a faster speed. Its cutting surface is also smooth, hence resulting in a smooth and good quality cutting.

  • What gas do you need for a plasma cutter?

A plasma cutter uses different kinds of gases. However, the most popular ones are oxygen, argon, nitrogen, hydrogen, and air. Most of these gases work well when cutting a thin sheet with about an inch thickness. However, when the metal sheet becomes thicker, a combination of two or more gases is used.

  • What can a plasma cutter cut?

A plasma cutter typically is to cut through electrically conductive metals and materials such as steel, aluminum, copper, brass, and stainless steel.

  • How thick can a 50 amp plasma cutter cut?

A 50amp plasma cutter can cut up to a thickness of one inch.

Final Verdict

Having gone through the eight plasma cutters and observing their relevant features and incredulity. There is no need to search any further. One of these could be the best plasma cutter for you. The detailed explanation has made it easier to choose from.

Our favorite of the eight best plasma cutters were the LOTOS LTP5000D 50Amp Arc plasma cutter. With a 10-50Amp cutting range, a non-touch pilot arc, 110/220v, and a cut of up to 12” thickness alongside a considerable price, it wins the heart. It’s impressive, though not as perfect and heavy-duty as others, it is our favorite low-cost plasma cutter.

The PRIMEWELD 3-in-1 50Amp plasma cutter, being one of the best plasma cutters for professional cutting, is a shocker. It is a heavy-duty 3-in-1 cutter, incorporating a welding stick alongside a plasma cutter. This unit is rugged, durable, and versatile, yet portable, compact, and mobile. The higher the price, the more the quality seems to be right about this set. Though indeed expensive, it is a sure one-time investment that would yield you good fortunes.

With all said, we hope you now have clarity and wouldn’t be confused the next time a plasm cutter purchase is to be made.
