A plasma cutter is a handy and useful tool as they require less energy to operate and is very easy to use. They are lightweight, so you can use them for a long time, without hurting your arms.
You can also find a plasma cutter under 500. This makes it more affordable. If you are new and don’t know anything about a plasma cutter, then this is the right place. In this article, I will give you a brief idea about plasma cutters, what to look for while purchasing, and some of the best plasma cutters available in the market, which are under 500.
All the items I picked up have excellent user ratings and are trusted in the market for a long time.
What is a plasma cutter?
A plasma cutter helps you to cute different types of metals. You can cut anything like stainless steel to aluminum to copper. The basic idea on which a plasma cutter works is to convert oxygen, nitrogen, or argon gas into the fourth state of matter, or you can say a plasma. In the cutting process, a gas is blown through a tiny nozzle to increase the velocity. Then the high-velocity gas is passed through an electric arc and gets a high temperature. That extreme heat converts the gas into a plasma. A heated torch is then used to cut through the plasma. The surface that you want to cut is covered by plasma, which makes it easier to cut through.
Things to consider before buying a plasma cutter
Buying a plasma cutter under 500 is tricky. You need to make sure that you are buying something that is useful and will do your job. As you want to buy something under 500, so it should be efficient as well worthy of that price. You should keep in mind a few things before you purchase a plasma cutter.
Inverter: Not every plasma cutter comes with an inverter. The one that does come with a big price tag. The inverter takes direct electricity and feeds it through high-frequency inverter and 10kHz to 200 kHz, adding to its portability feature. So, buy an inverter included plasma cutter if it fits your budget.
Voltage: Plasma cutter with operating within 110V to 220V wall outlets are cheaper. But they have limited functionality. The plasma cutter that can work on up to 440V is much more efficient and cut through thicker material. So consider the voltage capability if you are in a budget.
Metal Thickness: The thicker your metal is, the more power you will be needing. Twenty-five amps will cut through one-fourth inches of metal. Where 50 amps will cut through half inches of metal, so select your plasma cutter depending on the type of work you do.
Operation: Modern plasma cutter has an LED indicator that makes it easy to operate. Typically, you need to set the controls depending on the material you are working on. LED indicators make things easy.
Timespan: If your plasma cutter provides high amperage, then it is more likely to get a longer lifespan. For a longer time, buy a plasma cutter that provides more significant amperage.

Frequently Asked Questions:
Are Lotos plasma cutters any good?
Ans: You can make your cutting jobs safe and efficient with the lotos LTP5000D Plasma Cutter. However, this cutter is designed for DIY and light welding works. Again, it’s also the right choice for use in harsh environments. Its AC/DC power source and dual voltage capabilities make it one of the most versatile cutting tools out there.
Do plasma cutters need air compressor?
Ans: Plasma cutters need an air compressor to cut in a two-stage process. Firstly, the arc heats the metal until it’s semi-gaseous. Then, the plasma is forced by blasts of the air to finish the cut. So, all plasma cutters require an air compressor to generate enough air pressure for your task.
What is oxy acetylene used for?
Ans: Oxy-acetylene is used for cutting and welding. The welding process usually uses acetylene is known as oxy-gas cutting or fuel cutting. This process is used to weld materials that require temperatures as high as 3,500 °C. Oxy-acetylene is capable of producing the hottest flame.
What is air pressure best for plasma cutting?
Ans: The plasma cutter needs 4-8 SCFM delivered at 90-120 PSI. It can cover up to 7 to 8 –inch steel.
Do you need a compressor for a plasma cutter?
Ans: All plasma cutter comes with a compressor. You need minimum airflow and pressure to cut metals.
Do I need gas for plasma cutting?
Ans: Compressed gas is mostly used for plasma cutting. It can also be used for plasma gauging on carbon steel.
Can plasma cutter be dangerous?
Ans: If you inhale, then hex chrome can increase the risk of having lung cancer. If it contacts skin, it can lead to skin irritation. So it is better to use a welding helmet.
