- Page 14 . pecification and Operating Principle The Multiplaz-3500 portable plasma system is a source of low-temperature plasma obtained by heating to ionization temperature vapors of a process fluid placed in the torch prior to operations The system is designed for continuous operation (duty cycle of 100%).
- Page 15 3.2 T orch Operating Principle Once the torch is filled with the proper fluid, the power supply is connected, and voltage is applied to the cathode (the ON button is pressed), the operator can cause the torch to produce an arc by pressing the start button briefly This results in the cathode shorting to the torch nozzle As the start button is released, an electric arc is produced between the cathode and nozzle Arc energy heats the nozzle, which in turn heats the evaporator, which causes the fluid to heat and turn into steam Steam flows toward the nozzle outlet...
