The system is equipped with a slow blow fuse rated for 0 (fuse dimensions: diameter 2 А . mm length mm, i.e. diameter / in - length 1 / in) . Please contact your authorized dealer with any questions about the 2 A fuse. Additional system safety is provided by a limitation of 68 V imposed on idle voltage between torch nozzle and workpiece metal unit housing in the absence of a direct arc. - Page 13 To connect any torch other than the Multiplaz-3500 to the Multiplaz-3500 power supply To connect the Multiplaz-3500 torch to any power supplies other than Multiplaz-3500 To connect torch to any outside sources of process fluid gas bottles, compressors fluid tanks etc.
- 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 7.1 . 6 Repair, Service, and Support 3.2 T orch Operating Principle Repair and maintenance are performed by authorized dealers. 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,...
