Mains supply

Mains supply requirements
High power equipment may, due to the primary current drawn from the mains supply, influence the
power quality of the grid. Therefore connection restrictions or requirements regarding the
maximum permissible mains impedance or the required minimum supply capacity at the interface
point to the public grid may apply for some types of equipment (see technical data). In this case it
is the responsibility of the installer or user of the equipment to ensure, by consultation with the
distribution network operator if necessary, that the equipment may be connected.
Make sure that the welding power source is connected to the correct supply voltage
and that it is protected by the correct fuse rating. Before connection and usage a
protective earth connection must be created in accordance with regulations.
