Invented by the Russian military, the MULTIPLAZ 3500 is a portable, multi functional plasma device for welding, cutting, soldering or brazing, melting, local heating, fusion and cleaning. It does not require any gas for welding or compressor for cutting. As it only uses water and alcohol as the power transfer source, there are no toxic fumes produced so welding in confined spaces is not a problem. The MULTIPLAZ can weld any type of metal over .3mm ferrous or non ferrous. It can also cut any material including steel up to 10mm. The duty cycle is 100% meaning it can be operated 24 hours a day, 365 days a year.
How does it work?
MULTIPLAZ uses low temperature plasma obtained by heating to ionization temperature vapours of a process fluid placed in the torch. Once the torch is filled with the appropriate fluid (distilled water for cutting and a water/alcohol mix for welding), the power connected, and the start button pressed to apply voltage to the cathode, an arc is produced shorting the cathode to the nozzle. Arc energy heats the nozzle, which then heats the evaporator which cause the fluid to heat and turn into steam. Steam flows to the nozzle under pressure at .4-1.2 bar and as it escapes from the nozzle the steam compresses the electric arc. Arc compression increases the arc temperature and the compressed electric arc heats the steam to ionization temperature.
The MULTIPLAZ uses 2 different modes. Either mode can be used for cutting or welding. Which mode is required for a particular job will depend on the material being cut or welded. Mode 1 is indirect arc mode, where the electric arc is produced between the cathode and the nozzle and the plasma jet is the only vehicle that transfers the energy to the work piece. Mode 2 is direct arc mode where the conductive work piece is part of the cutting or welding circuit and the electric arc is produced between the work piece and the cathode inside the plasma jet.
