Plasma Cutting is process by which all types of conducting materials can be cut. This is an economic commonly used process for steel cutting in the industry today. Plasma arc is generated in a device called Plasma Torch. Compressed air, Argon, Nitrogen , Argon + Hydrogen ( 65%+35%) gas is used as plasma gas based on metals and quality requirements. Pilot arc is generated in the torch which oozes out of the nozzle and is thrown on to the job to be cut. Plasma arc is established between the cathode in the torch and the job which is anode through constricted hole in the nozzle. Plasma arc temperature is quite high ( in the range of 11000 degree C to 300000 degree C). The metal under cutting melts instantaneously and is thrown down by the kinetic energy of the Plasma arc. Electrical capacity of the power source decides the max. cutting capacity.
