The inverter technology applied to plasma cutting has enabled electro c.f. to develop a range of plasma metal-cutting inverter power sources with high duty cycle combined with low weight and compact dimensions. In the three-phase models, automatic setting of appropriate voltagewithin the following ranges: 3x208220230V and 400440VAutomatic detection of phase presence both upon start-up and during operationPilot arcHigh FrequencyVoltage startPost-gas functionSelf Restart Pilot function for nets and grids cutting, for the models PLASMA 76 and 106Safety systems on the torchElectronic regulation of cutting currentControl and gauge for the presence of compressed air flow and thermostatic protectionMicroprocessor-controlled cutting parameters and functionsCutting current is not affected by voltage fluctuations, by change of distance between torch and piece as well as by the torch traveling speedTheir standard equipment includes the manual torch and the grounding cable
