Choose the place where the welding machine is to be installed so that there are no
obstructions to the cooling air inlets and outlets; at the same time make sure that
conductive dust, corrosive vapours, humidity etc. cannot be drawn into the machine.
Leave at least 250 mm of free space all around the welding machine.

- Before making any electrical connection, check the rating plate data on the welding
machine to make sure they correspond to the voltage and frequency of the available
power supply where the machine is to be installed.
- The welding machine must be connected only and exclusively to a power supply with
the neutral conductor connected to earth.
- To guarantee protection against indirect contact use the following types of residual
current devices:
- Type A ( ) for single-phase machines.
- Type B ( ) for 3-phase machines.
- In order to satisfy the requirements of the EN 61000-3-11 (Flicker) standard we
recommend connecting the welding machine to the interface points of the main
power supply that have an impedance of less than Zmax = 0.24 ohm.
- The welding machine is not within the requirements of standard IEC/EN 61000-3-12.
If it is connected to a public power mains, the installer or the user is responsible for
checking the welding machine can be connected (if necessary, consult the mains
power supply provider).

Table 1 (TAB. 1) gives the recommended values for welding cables (in mm 2 ) according
to the maximum energy supplied by the welding machine.
In addition:
- Fully rotate the welding cable connectors in the quick couplings (if present), to
guarantee perfect electric contact; if this is not the case the connectors will overheat
ZLWKFRQVHTXHQWIDVWGHWHULRUDWLRQDQGORVVRIHI¿FLHQF\
- Use the shortest welding cables possible.
- Do not use metal structures that are not part of the workpiece to replace the welding
current return cable; this can endanger safety and give unsatisfactory welding
results.
