And if you are fabricator LTP5000D would be the best for you.

Buying Guide

Before selection of plasma cutter you will take a look on some factors like purpose that may be for the fabrication shops, automotive repair shops, vehicle restoration, salvage recovery, scraping works or whatever then a comparative study of the machines of different brands to be done regarding overall features, performance, quality, service, and the budget above all.

What is plasma cutter ?

A plasma cutter is a machine that allows the user to cut different electrical conductive metals by high-temperature electrical channel of plasma. It works by sending an electric arc that passes through plasma with a constricted opening. The plasma cutter requires continuous air pressure, which is supplied by an air compressor.

Plasma cutting is a process by which thick and thin electrical conductive materials like stainless steel, alloy steel, mild steel, copper, aluminum, cast iron, brass.

Hand-held plasma cutter torch can usually cut up to 2/3 inches (38 mm) thick steel plate and stronger CNC (Computer Numerical Controlled) torch can cut steel up to 6 inches (150 mm) thick steel plate. 

What is plasma ?

Plasma is one of the four states (solid, liquid, gas, plasma) of mater which is created in the gaseous medium at a high-temperature due to ionization of gas. It transfers the energy from a power supply to the electrically conductive material. An air compressor by its pressure helps to send an electric arc through this plasma with a constricted opening. Plasma contains charged particles which respond to electric and magnetic field better than gases.

How does plasma cutter work?

Plasma cutter produces a very hot and much localized cone to cut with. They are extremely useful for cutting the metal sheet in curved or angled shaped. This is often used fabrication shops, automotive repair shop, vehicle restoration, salvage, automotive recovery, scraping works, infrastructure and construction.

What gas uses a plasma cutter?

Most of the hand-held systems use compressed air (shop air). Someone uses a mixture of Argon and Hydrogen while cutting thicker stainless steel or aluminum. Some people use a mixture of hydrogen and nitrogen, or methane and nitrogen when cutting thinner stainless Steel.

Pilot Arc Plasma Cutter

Pilot arc plasma cutters do not need to touch with the metal you want to cut. Pilot arc torch efficiently cuts though rough, painted, and rusty surfaces producing minimal slag. You are required to spend comparatively less money on changing the consumables while using Pilot Arc Plasma Cutter. Pilot arc plasma cutter features-

  1. Use contact start with moving electrode inside the torch.
  2. DC power
  3.  Pilot arc torch efficiently cuts through rough, painted and rusty                    surfaces  producing minimal slag.
  4. Pilot arc technology allows to cut without touching the tip to the                     metal.
  5. Better cutting quality and longer consumables life. 

Non Pilot Arc Plasma Cutter

Non pilot arc torches work well on clean metals, although having to touch start a torch is extremely tough on the torch nozzle (tip), as the arc starts with the nozzle in contact with the plate and molten metal has no where to go except right back on the nozzle orifice.

High Frequency Plasma Cutter

The high-frequency plasma cutting machines use high-frequency circuit to ignite the pilot arc. These machines contain electrode and nozzle in a fixed position. The arc jumps the gap and the air blows the arc out of the nozzle. The high intensity spark obtained by high-frequency and high-voltage Alternate Current (AC) used to heat the plasma gas. Most of the modern industrial plasma machines use the HF method. These machines are reliable and especially high duty purpose and unsure faster and more precise cutting and mandatory for business and professional use.

What is Plasma jet ?

In cutting torch an electric arc is formed between the Electrodes (made of copper, tungsten, graphite, molybdenum, silver or by other material) and the thermal plasma (formed from the continual input of carrier gas) producing the plasma jet. The flow rate of carrier gas can be raised to larger and more projecting plasma jet. The plasma-Jet is safe, effective, easy-to-use and designed to cut the metals.

Standard amperage and voltage for Plasma Cutter

In general, a ¼" machine has approximately 25 amps of output, a 1/2" machine has a 50-60 amp output while a ¾" - 1" machine has 80 amps output.

Plasma Cutting Torch

Plasma cutting torch is a device for generating a directed flow of plasma by means of an accelerated jet. It is also known as plasma arc, plasma gun, or plasma cutter. The plasma cutting torch has different parts:-

  1. Torch body: The torch body is made of high-quality material that                   contains a micro switch to control the plasma cutting.
  2. Electrode: Carries negative charge from power supply.
  3. Swirl ring: Spin the plasma gas into a stable, swirling vortex.
  4. Nozzle: Constrict and focus the plasma jet.
  5. Shield: To improve the cut edge
  6. Retaining cap: To circulate the coolant around the nozzle. 

Cutting capacity

Plasma cutting machine cuts both the thick and thin materials alike. Hand-held torches can usually cut up to 1.5 inches (38 mm) thick steel plate. The stronger computer-controlled (CNC) torches can cut steel plate up to 6 inches (150 mm) thick.

MOSFET Technology

MOSFET (Metal Oxide Semiconductor Field-Effect Transistor) is a semiconductor device. It is widely used for switching and amplifying electronic signals in the electronic devices. It is actually a voltage-controlled power switching/amplifying device. It delivers high current to the load current. The MOSFET technology is required almost no current to load current.

IGBT

IGB (Insulator Gate Bipolar) Technology is a semiconducting electronic device used as an electronic switch that comes to combine high efficiency and fast switching. It provides fast switching and high current with moderate speed,

BJT Technology

BJT (Bipolar Junction Transistor) is used for low current applications whereas MOSFET is used for high power applications. Nowadays, in analog and digital circuits, MOSFETs are treated to be more commonly used than BJT.

Transistor

Transistor, the word has come from Transfer and Resistor. It works either as amplifier or switch. It amplifies electrical signal transferred from input to output terminals.

AC & DC current

Electricity or current is the movement of electrons through a conductor, like wires. Difference between Alternate Current (AC) and Direct Current (DC) lies in the direction of electron flows. In Direct Current electrons flow steadily in a single direction or forward. In Alternate Current electrons keep switching directions, sometimes going forward and then going backward, its frequency is 50Hz to 60 Hz depending upon the country to country. Alternate Current is safe to transfer at long distance and it can provide more power. Direct Current can’t transfer very far, its frequency is zero.

How does a pilot arc cut?

Pilot Arc plasma cutter allows cutting without touching the tip of the torch to the metal. This feature makes cutting the steel a lot easier and smoother. It performs better cutting and longer consumables life. There is a DC Arc that goes from the torch electrode to the to the torch nozzle. Pilot Arc is worth to be a newbie. It is mainly used to cut clean metals.
Non pilot arc plasma cutters are moderately cheaper that requires to touch the tip of the torch to cut the metals. In the long this Non-pilot plasma cutter counts more cost against its consumables. 

Inverter Plasma Putter

Inverter plasma cutter may or may not use the HF Arc starting that minimizes the size and weight to make portable. The torch/device uses compressed air and controls the machine from power fluctuation and steady flow.

High-frequency non-touch torch

There is a feature called standoff that keeps the torch away in a constant distance from the metal to be cut. Sometimes you can adjust the distance to change the type of cut you need.

Drag Technology

Drag technology is the easiest way to trace lines when you cut for artistic or decorative projects.

Touch start

Touch start is the least desirable technology in plasma cutting. The nozzle touches the metal to create the cutting arc here. Then the project to be lifted off and hovered the metal to finish the cut.

What is Ionization ?

Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes

Safety equipment’s

While working with a plasma cutter it is important to know safety measures i.e. the below safety gears are required use during working-

  1. Plasma Helmet: To protect eyes
  2. Welding beanie: To protect hair from sparks
  3. Welding jacket: To protect your arms and torso
  4. Welding gloves: To protect your hands
  5. Set of jeans: To protect your legs
  6. Laced and tied boots: To protect your feet from both sparks and                      dropping pieces of metal
  7. Fire extinguisher
