Get the best Used Plasma Cutter from Red-D-Arc

In Plasma cutting process, the machine cuts through an electrically conductive material by means of a jet containing Hot Plasma. You can cut several metals such as Steel, Stainless Steel, Aluminum, brass, and copper with the help of Plasma Torch. Owing to its multifarious benefits, spearheaded by slashed costs, the industries today are in dire need of used Plasma Cutter.

The working system

Plasma is the fourth state of matter. Electrically conducive gases when heated to a high level typically change their state to Plasma. The Plasma cutter uses this electrically conductive gas to transfer the energy from the power supply to any conductive material. This results in a cleaner, faster-cutting fuel as compared to oxyfuel.

There is an introduction of plasma arc when the gases such as oxygen, nitrogen, argon or shop air undergo a thrust through a small nozzle placed inside the torch. The electric arc generated from the external power supply is then put under a high-pressure gas flow to acquire the form of “Plasma Jet”. It takes no time to reach the temperature of about 40000 degree Celsius and cut through the exposed piece of metal.

You can group major systems into conventional as well as precision categories. The convention system uses the shop air as the plasma gas and the shape of the arc relies on the orifice of the nozzle. On the other hand, the design of the Precision plasma system is conducive to produce sharpest and highest quality cuts available through Plasma.

Used plasma cutter at Red-D-Arc

Due to reduced costs and assorted features, used Plasma cutter has been a revolution in the metal cutting industry. Unlike the other means, it provides the user high output with fewer efforts. As a result, major industries in concern with these metal tasks prefer this for better efficiency. 

Among the many manufacturers and suppliers of this machine, Red-D-Arc is a reputed name. The company holds a credible record of providing highly sophisticated, superior quality, and multi-purpose plasma cutters for varied industries. It also provides used plasma cutters at a reasonable cost for you to grab at the earnest.

Plasma Cutter – Working, Applications and Where to Rent From

Scientists refer to ‘plasma’ as the fourth state of matter that comes after solid, liquid and gas. The application of heat changes the solid form of water (ice) to liquid and then to gas (steam). Applying excess heat tends the gases to become electrically conductive and ionized, thereby acquiring the form of plasma. Hence, a plasma cutter leverages this electrically conductive gas to ensure a quicker and cleaner cutting process on any conductive material.

How a plasma cutter works?

The plasma cutting machine operates by creating a plasma arc, which results on forcing a gas through a constricted opening. The gas could be oxygen, nitrogen, shop air or argon and likewise, the opening could be a nozzle orifice within the torch. Next, an electric arc generated from an external power source combines with the high pressured plasma arc to give way to plasma jet. Rising quickly up to 40,000 degrees Fahrenheit, this plasma jet blows away the molten material and pierces through the workpiece. 

Applications

A plasma cutting machine is handy in cutting metals, creating metal workpieces, beveling, cutting holes, material gouging and so on. Hence, they find heavy use in assorted industries like shipbuilding, automotive restoration, steel fabrication, manufacturing, pipeline construction and more, where all such tasks are quite regular.

How Does Plasma Cutting Machine Work?

Plasma cutting machine came into existence with the purpose to cut materials through thermal cutting. Specifically, materials like aluminum, high alloy steels etc., which are not fit for flame cutting, are the best to cut through this machine. Nowadays, various industries also use it for economical cutting of thin and low allowed steels. Here is a brief intro of how this machine works, but before that, it is important to know what exactly is plasma.

About plasma

The theory of matter changing from one state to other with the introduction of heat is nothing new. For example, ice acquires the state of water, liquid and then gas on the application of heat. On applying heat in excess, the gases that form the steam turn electrically conductive and ionized to become plasma. Notably, a CNC plasma cutting machine leverages this ionized gas to perform its task.

Components of CNC Plasma Cutting Machine

• Power supply: It ranges from 200 t0 400VDC and is responsible for maintaining the plasma arc. It provides the requisite energy to maintain the plasma arc after the ionization process.
• Arc static circuit: This high-frequency generator circuit produces AC voltage of 5k to 10k volts at 2 MH approx. It creates a high-intensity spark inside the torch to create the plasma arc.
• Plasma torch: It provides apt cooling (gas or water) and alignment of the consumables like nozzle, electrodes, swirl ring, etc. To improve cut quality, the experts mostly use additional shielding cap for the torch 

These components altogether make up for the ionization capability, electrical energy, and process control required to make productive cuts on different materials with extreme precision and high quality.

Working Of Plasma Cutting Machine

A plasma cutter utilizes electrically conductive gas to transfer energy from an electrical supply to cut the material.Here are the important steps:

1. The formation of plasma arc takes places by forcing a gas like oxygen, nitrogen or shop air through a tiny nozzle orifice inside the plasma torch.
2. An external power supply ranging from 5,000 to 10,000 volts generates a high-intensity electric arc, which is exposed to this high pressured gas flow, ultimately resulting in plasma jet.
3. The temperature of plasma jet rises to 40,000oF within no time, making it easier to pierce through the molten material.

Advantages of Plasma Cutting Machines – An Alternative for Oxy-Fuel with Multifarious Benefits

Although, various traditional methods like oxy-fuel cutting machines are also available in the market, the plasma cutters have a cutting edge over others. 

Plasma Cutting vs. Oxy-Fuel 

An oxy-fuel cutting machine is another important tool for cutting materials like steel and aluminum. With such diverse options available in the market, you may find great difficulty in choosing the best. Of course, the selection becomes quite obvious when you compare the traditional tools with plasma cutting machines. 

Although, they both have their own advantages and disadvantages, the plasma cutters find their extensive usage in cutting of non-ferrous materials like stainless steel, aluminum as well as cast iron. Furthermore, when it comes to precision and speed, the plasma cutters offer many advantages over the oxy-fuel cutters.

CNC Plasma Cutting Advantages

Occupying a significant role in the manufacturing and construction industries, a CNC plasma cutting machine offers multiple benefits for the users including:

• Precision and accuracy: Unlike the traditional approaches of cutting materials, plasma cutting tends to offer greater precision and accuracy when it comes to cutting based on specific measurements. Designed with special gears, these cutters operate on computerized software.
• Greater efficiency: The great ease of cutting that these cutters offer to you makes the process much more efficient. Minimal training is needed so your operator can manage any kind of complicated adjustments comfortably.
• Diverse application: You can ideally use these machines for cutting a variety of materials whether ferrous or non-ferrous. In fact, you can also easily cut metals with more than a 3-inch gauge thickness.
