Plasma cutting machine is generally considered normal output voltage is cut. Plasma arc cutting machine usually has a higher load voltage and the operating voltage. When using high energy ionized gas, such as nitrogen, hydrogen or air. Stable plasma arc voltage requirement will be higher. When the current is constant, increase the ability to enhance and improve the cutting arc voltage means the enthalpy values. If the value increases enthalpy decreases and the diameter of the jet increase the gas flow rate. We can get faster cutting speeds and better cutting quality.
