9 USE WITH GENERATOR POWER SUPPLY
Using plasma cutting inverters with generator power supply may damage both the generator and the inverter. The generator to be used
must be sufficiently efficient and equipped with electronic voltage control. We recommend a generator of at least 10 kVA with electronic
voltage control. Values are approximate and we recommend using a larger generator. Machine is protected against ±15% voltage
fluctuations. Severe changes in the frequency of the alternating current of the generator or extremely violent voltage drop or surge may
damage the machine despite the protection system.
