supplies. Our torch isn ’t universal. It is designed with the power supply, tested with the power supply, and optimized to work best with the power supply. This is important because plasma torches develop an ionized gas arc between the electrode and nozzle then add DC energy to that electrical arc to increase the temperature up to 25,000 degrees Fahrenheit. This 25,000 degree arc is then forced through a copper orifice, which incidentally melts at 1,100 degrees, to make the arc perfectly... (read more)
