Plasma cutting may be a process that was developed from plasma welding within the 1950s and was designed to exactly cut both thin and thick materials. However, plasma cutting was not accepted by manufacturers and fabricators until the 1970s due to the cost of the system and the gases required, and the lack of knowledge surrounding the process. How much a plasma cutter cost? There are many inexpensive plasma cutters on the market, which start as low as $150, however, while these machines may make some impressive cuts it won’t be long before you need a replacement. You can get a great reliable plasma cutter under 500 dollars that can be very effective for you. How Does Plasma Cutter Works? Plasma cutters are becoming an increasingly common tool in many industries such as metal fabrication, construction, and automotive repair. This tool is able to cut through several types of metal including steel, copper, brass, and aluminum by generating an extremely high-temperature, electrical channel of ionized gas otherwise known as plasma. Is it require gas for the plasma cutter?
Gas is required for a plasma cutter so as for it to figure and make the plasma. The most popular gases to use are oxygen, nitrogen, or argon. Some plasma cutter systems include multi-gas features so a spread of gases are often used for various applications. Can a Plasma cutter cut through paint? Yes, a plasma cutter is in a position to chop through painted metal, however, it'll require a solid connection on a clean section of the metal that's as on the brink of the world you're performing on as possible. Which metals a plasma cutter can cut? A plasma cutter can cut various types of metals. The best plasma cutter under 500 dollars can easily cut Mild steel, Stainless steel, Aluminium, Copper, Brass, Cast iron, Titanium, Monel, Inconel. The best plasma cutter is always great for your welding & plasma cutting task. Hope this article will help you a lot to understand everything about plasma cutter & to buy the best plasma cutter under 500 dollars.

Plasma cutting (plasma arc cutting) is a melting process in which a jet of ionized gas at temperatures above 20,000°C is used to melt and expel material from the cut. During the method, an electrical arc is struck between an electrode (cathode) and therefore the workpiece (anode). The electrode is recessed during a water- or air-cooled gas nozzle which constricts the arc causing the narrow, heat, high-velocity plasma jet to make. How Plasma Cutter Works? Plasma cutters work by sending an electrical arc through a gas that's passing through a constricted opening. The gas is often shopped air, nitrogen, argon, oxygen. etc. This elevates the temperature of the gas to the point that it enters a 4th state of matter. We all are conversant in the primary three: i.e., solid, liquid, and gas. Scientists call this extra state plasma. because the metal being cut is a component of the circuit, the electrical conductivity of the plasma causes the arc to transfer to the work. How To Use Plasma Cutter?
1. Connect your plasma cutter to a suitable air compressor. 2. Connect your plasma cutter to a 240V or 415V supply (depending on the machine purchased). 3. Connect the earth lead to your workpiece. 4. Connect your plasma cutting torch to the plasma cutting machine. 5. Select your cutting amperage (more amps for thicker materials). 6. Press the switch on your torch handle and move the torch across the work as the plasma arc cuts the metal. How Much a Plasma Cutter Costs? The Best Plasma cutters are generally priced higher when it can produce a higher number of amps, but that isn’t always the case. You can get some of the best plasma cutters under 500 dollars. Some Entry-level plasma cutters will generally make a 0.25 inch (12mm) cut and pricing begin at $225. In the 0.25 inch to a 0.5-inch cutting range, there are several models that are in the $300-$400 range. If you need to cut through a 1-inch piece of metal, you may see prices in the $1,500-$2,000 range. Plasma cutting is a thermal cutting method. Which means that uses heat to melt the metal instead of mechanically cutting it. Plasma cutter uses compressed air or other gases, like nitrogen. Ionization of these gases takes place to create plasma. If you are a professional welder then it is a must to work with a plasma cutter. Before using any technology then you need to know about its advantages.
And after that, you need to find the best plasma cutter for your task. Buying a plasma cutter is always a difficult task. There are so many costly plasma cutters but if your budget is limited then here are some tips & things for consideration for buying the best plasma cutter under 500. Cutting speed
The first thing you need to pay attention to is the cutting speed. It determines how fast your machine can cut through thick metals & the quality of cutting. Generally, there are three types of cutting speed. They are Rated Cut, The Quality Cut & Serve Cut. Electric Output You need to be more aware of the output power. If you want to use it with household/workplace power then you must check it before buying otherwise you can't use it. Duty Cycle If you want the best plasma cutter under 500 dollars then you may get a machine with a medium or high duty cycle. This will help you to work faster & complete your job easily. Starting Type Plasma cutter uses high-frequency start or contact start. The starting is a bit risky while using it close to electronic devices & appliances since it produces lots of interferences. But the contact start technology will help to get rid of this problem. Portability If you are a professional welder & need to carry your best plasma cutter to your workplace then having an easy portability feature will help you a lot. Hope that these will help you a lot while buying your best plasma cutter under 500 dollars. A plasma cutter is a tool that uses an inert gas that is blown out at high speed from a triggered nozzle in its basic form. As this gas escapes, an arc is applied to it to create a super hot torch.
