Plasma cutting is a type of arc cutting characterized by the creation of a highly concentrated plasma electric arc that glows between the electrode and the material, which melts it and throws it out of the cut kerf. It is distinguished by, among others high efficiency and good quality of the cut edge. The optimal selection of plasma gases and cutting parameters allows to obtain the appropriate quality of the cut surface, virtually zero scale and high repeatability of the created elements. Automatic setting minimizes the amount of waste.
The undoubted advantages of plasma burners are high cutting speed, good quality of cut elements (possibility of obtaining a perfect, mirror edge surface with XD class plasma aggregates). Thanks to the high arc temperature, plasma cutting starts immediately with relatively little temperature effect on the entire material, resulting in a small kerf.
The disadvantages of this process include, above all, a high level of noise, a large amount of gases and fumes. They can be minimized by using a water dissecting table or an appropriate filtration and ventilation system.
Plasma cutting can be used to cut all conductive materials. In practice, however, this process mainly involves black steel, stainless steel and aluminum. Most often, they are used to make sheets, sections, pipes or meshes.
It is worth noting that cutting rusted, painted or dirty surfaces does not require prior cleaning. For optimal operation of the plasma cutter, only proper electrical contact of the ground cable with the cut element is necessary.
