Water injection in the Plasma Arc Cutting Process

As we all know water is used as a coolant in many industrial methods that involves high temperature for the process. Same ways water injection in the plasma arc cutting process also has a specific use. Water is injected through the injector into the plasma arc.

The plasma arc is generally got when Nitrogen is used as plasma gas in most of the plasma cutting machines. When the water is introduced to the plasma arc it induces a high degree of constriction. We can note that the temperature shoots up considerably to 30,000°C and above in this particular process.

If you compare the above process advantages with conventional plasma you can notice that there is a substantial Improvement in cut quality as well as squareness of cut. Apart from the improvement in cut quality we can also find an increase in cutting speed, less noticeable risk of double arching as well as decrease in nozzle erosion.
