Hi Definition Plasma Cutting Systems serve many industries due to their ability to work with different materials and different applications. MicroStep’s Plasma Cutting Systems can be adapted with various solutions. Here are just a few Pipe Cutting, Tapping and Drilling, 3D Bevel Cutting and I-Beam Processing.

I-Beam Processing plays a huge role in the Construction Industry as these beams play an integral part to any structure.

The traditional way of cutting and processing I-Beams, Channels and Angle Iron for the Steel Construction Industry is by either cutting the I-Beams with a cutting torch or a band saw and then use either mag base drills or CNC drilling lines to drill the holes into the sections.

MicroStep has developed the ProfileCut Plasma Cutting Machine, that has the ability to perform the following processes, all on one machine using Plasma Cutting Technology:

  • Cutting to length and at any angle also with bevels.
  • Cutting slots and holes
  • Plasma etch marking of numbers as well as weld positioning
  • Castellation
  • Coping of flanges

How does Plasma Cutting Work?

Plasma cutting works by passing a very swift jet of hot plasma through conductive metals to cut through it.

There are 5 key to any Plasma Cutting System

Power Supply

The power supply – this will convert either single or three-phase AC line voltage into a useful DC voltage of up to 400 VDC. This ensures that the plasma arc stays stable throughout the arc cutting process.

Arc Starting Console

The Arc Starting Console – this is a simple circuit that is designed to deliver an AC voltage of around 5,000 VAC at 2MHZ (which is very high-frequency) to produce the spark that launches the plasma arc


Gas flow is critical and plasma systems can use nearly any gas. Typically, nitrogen, oxygen and argon are used. These can serve two purposes:

  • to form the base of the plasma arc
  • to shield the plasma, to provide a better cutting experience


Plasma Cutters heat up quickly and get incredibly hot. If they didn’t have a cooling system the nozzle or electrode could catch fire, thus a liquid cooling system is built in and is used to keep the temperature under control at all times.


The Plasma Torch is designed to enable the proper alignment of the plasma arc and to ensure that the cooling system operates effectively. Consumables for a plasma cutter include nozzles, electrodes, and swirl rings.

Plasma Cutting Construction Industry


Structural steel fabrication services have numerous interior and exterior construction manufacturing applications. Expertly fabricated steel parts can help to reduce the overall weight of a building — without sacrificing structural integrity. Structural steel is also a highly malleable material, which provides endless possibilities for customization. Construction Companies can develop tailored construction industry fabrication solutions for every project requirement. This also makes it easier to modify a building in the future should the need arise to expand or add onto the structure.

Fabrication for the construction industry can also achieve a project’s aesthetic requirements. Architects love working with structural steel due to its combination of natural beauty and remarkable strength. Plasma Cutters can also be used in artistic applications in the building industry such as for making objects ornate. Ranging from gates, screens balustrades etc.

Plasma Cutting technology has grown tremendously over the years and these days it can be combined with many different technologies and robotic applications to give you a full house offering and allowing you to have control over your production output.
