The FastMig power source can be used in electrode welding by connecting a FastMig
MFS 53, MFS 55 or MSF 57 wire feeder to it. The power source can be made suitable for
electrode welding without a wire feeder by connecting an R10 or R20 remote control to the
X14 or X15 terminal at the back of the power source for welding current adjustment, and the
welding power cable connected to the power source’s (+) connector X11 or X12.
5. maintenanCe
The amount of use and the working environment should be taken into consideration
when planning the frequency of maintenance of the machine. Careful use and preventive
maintenance will help to ensure trouble-free operation.
5.1 Cables
Check the condition of welding and connection cables daily. Do not use damaged cables.
Make sure that the mains cables in use are safe and according to laid down regulations.
The repair and mounting of a mains connection cable should be carried out only by an
authorised electrician.

NOTE! Disconnect the plug of the machine from the mains socket and wait approx. 2 minutes
(capacitor charge) before removing the cover plate.
Check at least every half year:
• Electric connectors of the machine – clean the oxidised parts and tighten the loosened
ones.

joints.
• Clean the inner parts of the machine from dust and dirt e.g. with a soft brush and
vacuum cleaner. Also clean the ventilation net behind the front grate.
• Do not use compressed air, there is a risk that dirt is packed even more tightly into gaps
of cooling profiles.
