2.5.3 Cable positions for multiple machine configurations
When using two or more FastMig X units working on the same work piece, the right
positioning of voltage sensing cable and the earth return cable is important.
In order for the voltage sensing function to work properly, the earth return cable and the
voltage sensing cable for each FastMig X power source should be connected close to each
other and away from other units’ cables (see the pictures below).
2.5.4 Connecting to mains power
FastMig power sources are delivered as standard with 5 meters of mains power cable. No
mains plug is fitted at the Kemppi factory.
NOTE! If local country-based regulations state an alternative power cable is required, the mains
cable must be replaced in conformity with the regulations. Connection and installation of the
mains cable and plug should only be carried out by a suitably qualified person.
Remove the machine cover plate to enable mounting of a mains cable. FastMig X 350 and
X 450 power sources can be connected to the mains supply of 400 V 3~ .
If changing the mains cable take into consideration the following:
The cable is entered into the machine through the inlet ring on the rear panel of the machine
and fastened with a cable clamp (05). The phase conductors of the cable are coupled to
connectors L1, L2 and L3. The earth protection coloured green-yellow is coupled to the
marked connector.
If you are using 5-lead cable, do not connect the neutral conductor.

Generator use
If no mains connection is available, you can use FastMig X 350 and X 450 on a generator. The
minimum recommended generator output is 35 kVA. The greater the output, the more stable
is the FastMig X power source operation.
