What is Plasma Cutter?
Plasma cutting is a process in which a jet of
ionized gas at temperatures above 20,000 C is
useful to melt and expel material from the cut.
During this process, an electric arc struck
between an electrode and the workpiece. The
electrode recesses in water or air-cooled gas
nozzles constrict the arc that causes the
narrow, high temperature, high-velocity plasma
jet to form. When the plasma jet hits the
workpiece, recombination takes place, and the
gas reverts to its normal state. It emits intense
heat as it moves. This heat melts the metal, and
gas flow ejects from the cut. Plasma gases are
usually argon, hydrogen, or nitrogen. These
inert gases replace air, but it requires a
special electrode of hafnium or zirconium. It
uses compressed air and makes this variant of the
plasma process very competitive with the oy fuel
process. Additionally, it cuts carbon manganese
and stainless steel up to 20mm thick. Hence,
while choosing plasma cutter machines, make sure
to choose machines that have Hypertherm hpr260
consumables,

Hypertherm powermax 45 consumables. Because they
are easy to find and replace if and when
needed. Plasma arcs can cut a very wide range of
electrically conductive alloys, including plain
carbon and stainless steel, aluminum and its
alloys, nickel alloys, and titanium. This method
developed to cut the materials which could not
cut satisfactorily by the oxy-fuel
process. Normally, the component or sheet to
which you cut stays stationary, and only the
plasma torch moves. The cost of plasma torches
is low compared to other products using the
price of manipulation equipment it is common to
plugin multiple torches in a cutting
table. Plasma arc cutting carries out underwater
using special equipment.

How Plasma Cutting Works? The process in plasma
cutting and welding is it creates an electrical
channel of superheated, electrically ionized gas,
i.e., plasma. Forming a finished circuit using
an earth terminal is important while using the
plasma cutter. To achieve this, it uses a
compressed gas, which blows to the material at
high speed using a focused nozzle. Inside the
gas, an arc is formed between an electrode near
the gas nozzle and the workpiece itself. This
electric arc ionizes part of the gas and creates
an electrically conductive plasma channel. The
current from the cutting torch flows through this
plasma it radiates enough heat to melt through
the material. Simultaneously, high-speed plasma
and the compressed gas blow the hot molten metal
away and separate the workpiece. Plasma cutting
is a great way to cut thin and thick materials
compared to hand torches that can cut up to 38nm
thick steel sheets stronger computer-controlled
torches can cut up to 150 mm thick steel sheets.
Plasma cutters are very useful for cutting and
welding sheets in curved or angular shapes as
they are very hot. Make sure to have plasma
cutting machines which have

• hypertherm hpr260 consumables, hypertherm
  powermax 45 consumables.
• Every technology has advantages and
  disadvantages. Similarly, a plasma cutter has
  its advantages and disadvantages. Let me walk
  you through them in brief
• Advantages
• The operation of one or more burners depends on
  the series.
• Cuts off all electrically conductive materials
• Cuts of high alloy steel and aluminum materials
  in medium and large thickness
• It has an excellent performance in small and
  medium mild steel thicknesses.
• Plasma cutters have high strength structural
  steel with low heat input.
• They have high cutting speeds, i.e., up to 10
  times higher than oxy-fuel
• Plasma cutting guarantees automation
• Plasma cutting underwater allows very low heat
  exposure and low noise level at the workplace.

• Disadvantages
• It has a restriction of the use of up to 160 mm
  for dry cutting and 120 mm for underwater
  cutting
• It slightly wider kerf
• Has relatively high power consumption
• Laser offers high cutting quality
• It is very expensive compared to oxy acetylene
  cutting systems
• Conclusion
• Plasma cutters are one of the best innovations
  that can help fabricators create out of the box
  creation and unleash their creativity. Create
  the next big thing, and we are waiting to see
  what things you can create.
