A plasma cutter uses ionized gas to create extremely high temperatures to cut through metal. A plasma cutting machine is ideal for cutting thick and thin metal sheets. It gives users a clean cut without using traditional cutting processes like chisels, grinders, or other cutting tools.
However, the working and operating dynamics of a plasma cutting machine differ based on the type of machine, making it imperative to invest in the type most ideal for one’s project needs. Below are some of the common types of CE plasma cutting machine based on cutting mechanism and operational mode:
Cryogenic plasma cutters are used to cut highly reactive non-ferrous metals (like aluminum) that cannot be cut otherwise. These plasma cutters utilize cryogenic (or ultra-cold) technology to stabilize and reduce the reactivity of the cutting material. They work great for giving clean, smooth, and oxidation-free cuts.
These machines are used for cutting metal sheets and plates. They are the most commonly used and are structured to cut ferrous and non-ferrous metals. Conventional plasma cutting machines can be used to cut metals that do not require fine detailing, i.e., where gouging or grinding is not a problem. Conventional plasma cutting machines are normally compatible with CNC systems for cutting larger sheets. These machines can also be used in welding and metal fabrication processes.
High-definition plasma cutting machines are designed to give more favorable results regarding cut quality, kerf width, and metal thickness. This machine is often used where detailing and surface finish are important. These are mostly employed in industrial cutting operations where large quantities of metals with precise dimensions need to be cut. While HD plasma cutting machines bring many benefits, especially in industrial cutting, the overall cost of the machines is relatively high.
These machines use compressed air as the plasma gas. Air plasma cutting machines are popularly used to cut thin materials up to 1.5 inches thick. They are best suited for maintenance operations and in workshops.
The plasma cutting machine is suitable for a wide range of applications and industries because of its versatility, efficiency, and ability to cut various metals.
It is used to cut metal plates into specified dimensions for further processing in welding, bending, etc. These cutting machines are common in metal fabrication workshops, as they easily handle bulk cutting operations. The automation capability of CE plasma cutting machines makes them especially appropriate for large-scale production in manufacturing industries.
Plasma cutting machines are used in the automotive industry to cut metal plates that are used in car body construction and other engine components. Their ability to cut complex shapes and give clean cutting edges makes them advantageous in assembling the desirable precision in the automobile manufacturing process.
Plasma cutting machines are widely used in the construction industry to cut metal frames, reinforcements, and structural supports. They are also used in shipbuilding for cutting steel and other metals used in constructing ships, barges, etc. Their speed and efficiency make them suitable for cutting large metal sheets and plates used for building structures and vehicles in these industries.
In the HVAC (Heating, Ventilation, and Air Conditioning) industry, plasma cutting machines are used to cut metal ducts, vents, and other components used in air distribution systems. The ability to cut intricate designs allows for tighter fittings and better airflow management within HVAC systems.
Due to the capable cutting ability of plasma cutting machines, they find a place in the aerospace industry for cutting materials like aluminum and titanium. These materials are cut to manufacture aircraft components, frames, and wings.
IGBT Technology
The CE plasma cutting machine incorporates IGBT technology in the inverter system for better energy efficiency, which helps manage the thermal load and enhances machine lifespan. This technology also ensures better plasma arc stability, improving cutting speed and quality.
Automatic Pressure Regulation
The CE plasma cutting machines came fitted with automatic pressure regulators to ensure consistent plasma gas pressure irrespective of working conditions like pressure or elevation changes. This enables stability in arc and gas flow, which means improved and consistent cutting performance.
Heavy-Duty Build Quality
The CE Plasma cutting machines are constructively designed and built to be heavy-duty for increasing reliability and use in demanding industrial environments. The internal components, including the nozzles, electrodes, and torch assembly, are made of wear-resistant materials, e.g., copper and tungsten, to withstand extensive use without degrading performance.
High Efficiency
CE plasma cutting machines are designed to provide maximum energy output with minimum energy input. They are generally more efficient than conventional gas cutters and allow the user to save energy costs in the long run. They also cut rapidly, helping conserve time.
Non-contact Cutting
The plasma arc does not have to touch the metal surface during cutting; thus, no mechanical stress is exerted on the surface. This minimizes metal deformation and allows the operator to work on sensitive workpieces. The non-contact cutting also helps to give a smooth surface finish.
Unpacking
The plasma cutting machine should first be unwrapped, and its damage should be inspected. The user manual should also be scanned and read. Suitable arrangements of the machine's components should also be made, as this will ease the installation process.
Placement
The place for safely and securely installing the IGBT plasma cutter should be identified. The area should be dry, clean, well-ventilated, and free of flammable materials. Additionally, a nearby power source and a worktable for placing workpieces were also considered.
Assembling
The assembled components, such as the torch, ground clamp, and plasma lead, should be connected per instructions regarding the manual. In machines with CNC capabilities, the plasma cutter should be hooked up to the designated CNC controls.
Connection
Apart from connecting the power cord to a suitable power source, the plasma gas and compressed air should also be hooked up to the machine. The machine needs further testing by powering it up and checking for operating issues.
Regular cleaning
Regular Cleaning: The cutter should always be cleaned after use to remove metal dust from the work and plasma cutter. Cobwebs and dust should be removed from the machine. Daily cleaning enhances the durability and efficiency of the machine.
heat monitoring
The machine should be allowed to cool off occasionally, especially when the machine has been overworked. Most machines are designed with heat dissipation aids, so these should be used to prevent overheating. Monitoring internal heat levels is also mandatory to ensure proper functioning.
checking the electrical connections
Electrical connections (cables, clamps, and other attachments) should always be inspected for damages (cracks or breaks). Any damage has to be fixed instantly to prevent occasional electric shocks from exposed wiring or, in the machine's underperformance, for safety reasons. Using original parts also contributes to safety and durability.
Referring to the manual
The maintenance schedule in the user manual should always be referred to for helps, as they provide professional maintenance tips and timelines for various activities like part replacement. Adhering to the maintenance schedule keeps the machine in good working condition even after long use and abuse.
Cutting Accuracy
Quality factors are usually evaluated based on how accurately the machine has cut metal sheets and plates. CNC plasma cutters are especially evaluated based on their kerf width, cutting speed, and precision in producing intricate shapes. Further, the thickness of the metal that can be cut while maintaining accuracy also defines the machine's quality.
Material Compatibility
People evaluate the quality of plasma cutters depending on the types of materials that they can cut. High-quality plasma cutting machines can cut through a wider range of metals, from thin gauge to thicker materials. They are also compatible with both ferrous and non-ferrous metals like steel, aluminum, and copper.
Durability and Build Quality
CE standard machines are always put through tests to assess machine durability and the quality of the materials used to manufacture the machines. Such a device is a heavy-duty one that can withstand prolonged use without frequent breakdowns or wear and tear. Components like the torch, nozzle, and electrode are checked for long-lasting materials, e.g., tungsten and copper, from which they are made, as these are more durable.
Power and Performance
Quality considerations are also evaluated based on the performance of the machine. Stronger and better machines can work at higher amperage or voltage. Thus, they can handle thicker materials and perform under industrial workloads. Further, quality machines provide a more stable plasma arc, thus ensuring cleaner cuts.
Proper ventillation
As plasma cutters generate ozone and harmful fumes, it is ideal to always operate the machines in well-ventilated areas or employ other means to enhance airflow. In areas with no ventilation, oxygen-retaining gas should be used to fill the plasma cutter's work area to avert explosions and other health challenges.
Using a Fire retarding cloth
A fire retarding cloth should always be put on plasma cutting workpieces, as sparks and molten metals can lead to fire accidents. Further, other adjoining flammable materials should be removed from the area.
Personal Protective Equipment (PPE)
A parallel emission of plasma arc light can lead to eye and skin burns, so personal protective equipment (PPE), including welding jackets, helmets, and gloves, should be worn. Further, other items of PPE, such as industrial shoes, and face shields, should also be worn to protect from sparks, electric shocks, and flying debris.
A1. Plasma cutting machines are designed for non-contact cutting; hence, the cutting tip stays about 1/16 of an inch above the work surface. The plasma cutter produces a plasma arc that reaches temperatures above 20,000 degrees Fahrenheit, which is hot enough to melt the metal.
A2. Plasma cutting machines can cut metal sheets and plates of varying thickness from a few millimeters to several centimeters. The thickness also largely depends on the machine's amperage rating and the type of metal being cut.
A3. The primary difference is that flame cutting uses an oxy-fuel gas while the plasma cutting machine uses highly ionized gas. Plasma cutting is quicker than flame cutting; thus, it is best for cutting thicker sheets or plates of metals. Plasma cutting is more precise and provides a cleaner cut with less heat-affected zones (HAZ) than flame cutting.
A4. To maintain a plasma cutter, more attention needs to be given to the torch and consumables. Daily, plasma leads are also checked for work, and ground clamps should also be checked. The work area and the machine should also be cleaned regularly to remove metal dust and debris.
