We offer a course on acetylene-oxygen, plasma and electric torches, which are some of the most popular tools used to separate low-carbon and low-alloy metals. At our centre, you will learn all the necessary information about working as an operator.

Types of cut 

Gas cutting involves bringing a metal to what is known as its ignition temperature. On contact with the burner, it burns and then escapes in the form of metal oxide. Appropriately designed torches can mix specific proportions of combustible gas with oxygen. Materials such as propane-butane and acetylene are used as combustible gases.  

Cutting with acetylene is an extremely efficient method due to its ability to reach high temperatures. Its additional advantages are mobility, the high quality of metal cutting and the option to mechanise the cutting processes using it. This method is used in many industries and, among others, in small workshops or large production halls.  

Gas cutting can be used to work cast iron, bronze, brass, steel and various metal alloys, as well as for brazing, heating or firing. Gas welding involves heating the workpiece by means of a flame to a suitable temperature so that it degrades and changes its state of aggregation. This makes it possible to permanently weld or separate steel workpieces as thick as 300 mm. The correct type of torch is responsible for the effect and quality of the cut. A smaller torch means a smaller stream. This means greater precision. Torches are used for cutting as well as for welding. However, not every metal is suitable for processing with this method. Suitable metals include bronze, brass, cast iron, iron, tungsten and titanium.

Plasma cutting aims to melt and eject metal from the cutting gap by means of a highly concentrated electric arc with high kinetic energy, which glows between the workpiece being cut and the non-fusible electrode. The plasma is generated by a torch. Passing a stream of compressed gas through the electric arc causes ionisation and, through high power density, produces a jet. A nozzle, which is located in the torch, focuses the plasma arc. The walls of the nozzle are cooled and cause the column to constrict. This method uses a high temperature (10000÷30000K) at the core of the plasma arc and an extremely high jet speed. This causes the material to be melted and blown out of the slit. In this method, the gas often used is air. Higher-powered units primarily use hydrogen, argon, carbon dioxide, nitrogen and argon-helium or argon-hydrogen mixtures. The plasma jet can cut materials that conduct electricity and are made of copper, aluminium and its alloys, brass, alloy or carbon steels and cast iron. 

We distinguish between the individual advantages and disadvantages of performing gas cutting 


  • small area of impact of cutting, 
  • good surface quality, 
  • small gap, 
  • rapid piercing, 
  • simple automation of the process, 
  • cutting range - from 0.5 mm to 160 mm, 
  • efficient vertical cutting, 
  • low thermal deformation, 
  • approximately 6 times faster cutting speed than oxy-gas cutting, 
  • little effect of temperature on the component, 
  • no burning of thin materials. 


  • changes in the impact area of the cut, 
  • noise (not applicable to underwater cutting), 
  • strong UV radiation, 
  • difficulties in maintaining perpendicularity of edges, 
  • high amount of fumes and gases that are harmful to health.
