This equipment complies with standards IEC 61000-3-12 and IEC61000-3-11 provided that impedance of the
supply line in the PCC is less than Zmax shown in the table. The fitter or the unit user are responsible for ensuring,
consulting the distribution network operator if necessary, that the equipment is connected to a power supply with a
maximum system impedance lower than Zmax.
The tables in section 11 show the technical data of welding power sources for the two processes used in the field of
industrial automation, which are the MIG/MAG processes. When in manual mode, the power sources are able to weld
using also coated (MMA) and TIG electrodes. For more details, refer to the instruction manual.
