Plasma Cutting
The basics of plasma cutting involve increasing the temperature of the material in a very localised manner and at a very high temperature, taking the material to the fourth state of matter, plasma, a state in which the electrons become dissociated from the atom.
This procedure involves sparking a strangled arc across the section of the torch hole, which is extremely small, massively concentrating the kinetic energy of the gas, ionising it, and through polarity it acquires the ability to cut. The main advantage of this system lies in its low risk of deformities due to the calorific compacting of the cutting area. The economy of the applicable gases is also appreciable, given that a priori, any type of gas is viable, although it must not attack the electrode or the part.
The equipment needed to provide this energy consists of a high frequency generator powered by electricity or gas, to generate the heating flame (argon, hydrogen, nitrogen) and an electrode holder, that depending on the gas, can be tungsten, hafnium or zirconium.
Plasma cutting attains greater precision and cleanliness of the cutting area than with conventional
oxycutting.
This is a complementary process for special jobs, such as the production of small series,
attaining precise tolerances or improving finishes.
