Metals can be cut with plasma cutters in both simple and sophisticated shapes, including holes, bevel edges, gouge, and marks. 3 Phase Plasma Cutters are utilized in industrial, commercial, and do-it-yourself applications as a practical and affordable substitute for oxyfuel, laser, and water jet cutting techniques. All kinds of businesses employ 3 Phase Plasma Cutters, including the manufacturing, pharmaceutical, oil and gas, and defense sectors.
When a gas is heated to very high temperatures, the molecules' electrons separate from their nuclei, converting the gas to plasma. By aiming the plasma jet through the metal, plasma cutting is performed.
Advantages Of 3 Phase Plasma Cutters
- having the ability to cut through all electrically conductive materials, including stainless steels and non-ferrous alloys (aluminum, brass, copper, etc.). Observation: Oxy-acetylene cutting is not suitable for cutting stainless steel or non-ferrous alloys.
- excellent cuts
- Because the machinery is lightweight and portable, it may be utilized for manual cutting on a construction site.
- Automation is simple to implement, much like other cutting processes.
- Complex forms can be rapidly sliced with CNC plasma cutting machines.
- cutting metals up to 6" thick with effectiveness.
Various 3-Phase Plasma Cutters Cutting Techniques
Different gases are utilized depending on the type of metal being cut. For cutting carbon steels, inert gases like argon or nitrogen are typically utilized, whereas compressed air or oxygen is typically used for cutting stainless steels. You can run on separate plasma and shielding gases to maximize performance with a dual gas system (plasma and shielding gas), for example, Air/Air, O2/Air, N2/Air, N2/CO2, Ar-H2/N2, or other combinations. Gases that serve as shields aid in torch cooling as well. In addition, liquid-cooled torches with optimal cooling and long consumable lives are offered for high-power applications.
Internal Compressors
For lighter cutting applications, plasma cutters that have an integrated air compressor are offered as portable machines. Plasma cutting on remote sites is made easier by Miller's Big Blue Air Pak, which combines power generation with compressed air.
CNC Equipment With a Water Bed
Plasma cutting on CNC machines is done with the water under or completely covering the workpiece as an alternative to fume extraction systems. This offers a fume removal alternative that is more affordable. The noise generated by the plasma-cutting process is also muted by the water bed. Additionally, underwater cutting reduces distortion, which is very helpful for cutting thin materials.
Plasma/Arc Start
Pilot arc and touch are the two sorts of available arc starters. In a touch arc start, the nozzle must make contact with the workpiece in order to initiate the arc, whereas, in a pilot arc, the plasma nozzle already contains an arc and no contact with the workpiece is necessary.
In order to ionize the gas, high frequency starts to rely on high frequency and voltage power. It can be used to start the plasma with a touch or a pilot arc torch. High-frequency starting has the drawback of potentially interfering with nearby electronic circuitry.
In back blow plasma initiation, a piston's movement ignites a flame inside the torch, starting an arc and ionizing the gas. Regardless of whether the nozzle is in contact with the workpiece or not, this arc creates the pilot arc and remains lit.
Which Two Types Of Plasma Cutters Are There?
Conventional and Precision plasma systems make up the majority of plasma cutting systems. Typical shop air is used as the plasma gas in conventional plasma systems, and the torch's nozzle determines the form of the arc.
