Types of cuts and their specific characteristics

This type of cutting is known as gas cutting or oxygen cutting. It is a commonly used method of separating metals. This method is most commonly used to cut unalloyed steels and low alloy steels.

  • Plasma cutting

Known as a metal cutting technique, the essence of which is to melt metal and eject it from the cutting slot. The whole process is carried out by means of a special plasma arc, acting under the influence of high kinetic energy.

  • Electrical cutting

This type of cutting provides a better cut surface quality and increased productivity compared to manual cutting. By using oxygen to cut structural carbon and low alloy steels.


Oxy-acetylene cuttingPlasma cuttingElectrical cutting
What is it about?This process involves heating the material to ignition temperature using a flame, followed by combustion and subsequent blasting of the liquid metal with a pressurised oxygen jet. The method makes it possible to cut metal sheets up to 30 cm thickThe material to be treated melts and is then blown out of the slit. Such a process is made possible by cutting technology using high temperatures at the core of the plasma arc, as well as high jet speeds.


The cut is made in two directions, perpendicular to the base or at an angle of 0 ÷ 45°. It can be driven by hand directly on the material to be cut, on a rail guide, according to an angle iron or with a circular saw. However, forward running is recommended

  • Oxy-acetylene cutting - is used when thicker materials made of ordinary steel need to be cut.
  • Plasma cutting - the most common applications for plasma cutting are the treatment of conductive materials such as aluminium, stainless steel and black steel.
  • Electrical cutting - the main applications of electrical cutting include cutting machine parts and structural components in steel construction plants and in craft workshops.

How do I obtain a torch cutting licence?

Thinking about cutting work with a torch? By law, in order to do cutting work, you must first try to obtain a licence, which is issued by an accredited training centre.
