Plasma Cutting

We use plasma cutting to dismantle structures and cut metal beams and plates. We use plasma cutting when gas cutting is not possible. This applies to some metals (stainless steels, aluminum, copper), as well as in situations where higher accuracy requirements apply to workpieces.

Plasma cutting is significantly quieter, has a low thermal effect and can be performed under water. The effect of gases and ultraviolet radiation is also minimal. The cutting takes place under the influence of a plasma jet, the temperature of which exceeds 25,000 °C. A pilot arc is first ignited between the tip of the tungsten, hafnium or cerium electrode and the parts, after which the plasma arc ignites. The process is characterized by a relatively high no-load voltage - up to 400 V. Thermal energy melts the serve and the jet removes the molten metal from the cutting zone.

The advantage of plasma cutting is high cutting speed on thin and medium thickness materials. The disadvantage, however, is the cutting edge that tapers from the bottom, which creates a slanted cutting edge.
