Powers Source of the Plasma Arc Cutting Process
Plasma arc cutting process is one of the most efficient methods available to ensure sharp and perfect cut on any metal sheet of any desired thickness. The power required for such perfect cut is high and is attained by regulating that amount of plasma flow which is required for each metal sheet.
The power source for the Plasma Arc Cutting Process should contain a relaxed characteristic as well as a high voltage. Even though the operating voltage for sustaining the plasma used for the cutting process is on average 50 to 60V, the open circuit voltage that is required to kick off the arc is noted to be up to 400V DC.
On start, the first arc is created inside the cavity of the torch which is between the electrodes along with the nozzle. When the cutting is to be performed the arc should be transferred to the work piece and is hence called as the transferred arc mode.
