3. OPERATION CONTROLS
3.1 Main switch I/O
When you turn the switch into I-position, pilot lamp H11 on the front face is illuminated and
the machine is ready for use.
NOTE! Always turn the machine on and o with the mains switch, never use the mains plugs as a
switch.
3.2 Pilot lamps
The pilot lamps of the machine report the electric operation:
The green pilot lamp H11 when lit indicates that the machine is on and ready for use and it is
connected to the mains supply with the main switch in the I-position.
H12 indicates when lit that the thermal protection of the machine has been activated due to
over heating. The cooling fan will continue to run and cool the machine down and when the
lamp is o the machine is ready to weld.
3.3 Operation of cooling fan
In FastMig power sources there are two simultaneously operating fans.
• The fan is started for a moment when main switch is placed into position I.
• The fan will start during welding as the machine heats up and it will run for 1 to 10
minutes after the welding has stopped.

FastMig M 320, 420, 520
4. MANUAL METAL ARC WELDING
The FastMig power source can be used in electrode welding by connecting a FastMig
MXF 63, MXF 65 or MXF 67 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
When considering and planning routine maintenance, please consider the frequency of
machine use and the working environment.
Correct operation of the machine and regular maintenance will help you avoid unnecessary
downtime and equipment failure.
NOTE! Disconnect the machine from the mains before handling the electrical cables.
5.1 Daily maintenance
• Check the overall condition of the welding gun. Remove welding spatter from the
contact tip and clean the gas nozzle. Replace worn or damaged parts. Only use original
Kemppi spare parts.
• Check the condition and connection of the welding circuit components: welding gun,
earth return cable and clamp, sockets and connectors.
• Check the condition of the feed rolls, needle bearings and shafts. Clean and lubricate
bearings and shafts with a small quantity of light machine oil if necessary. Assemble,
adjust and test function.
• Check that the feed rolls are suitable for the ller wire you are using, and that their
pressure adjustment is correct.
EN
5.2 Periodic maintenance
NOTE! Periodic maintenance should only be carried out by a suitably qualied person. Disconnect
the plug of the machine from the mains socket and wait about 2 minutes (capacitor charge) before
removing the cover plate.
Check at least every half year:
• Electric connectors of the machine – clean any oxidized parts and tighten loose
connections.
NOTE! You must know the correct tension torques values before starting the reparation of the loose
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 grill.
Do not use compressed air, there is a risk that the dirt will compact even more tightly into
gaps of cooling proles.
Do not use pressure washing devices.
Only an authorized trained electrician should carry out repairs to Kemppi machines.

EN
6. OPERATION DISTURBANCES
Should you experience a malfunction from your machine, please consult the basic
troubleshooting text above rst, and complete some basic checks.
If the machine malfunction cannot be corrected with these measures, contact your Kemppi
maintenance service workshop.
Operation of the overload protection
Yellow thermal protection lamp is lit when the thermostat is operating due to loading beyond
the stated duty cycle.
The thermostat will operate, if machine is continuously loaded over rated values or cooling air
circulation is blocked.
Internal fans will cool the machine, and when the pilot lamp is not lit the machine is
automatically ready for welding.
Control fuses
Fuse, 6.3 A delayed, on the rear wall of machine provides protection for auxiliary devices.
Use the same type and rating of fuse as marked beside the fuse adapter. Damage caused by
incorrect fuse selection is not covered by the guarantee.
Under and over voltages in the mains supply
Primary circuits of the machine are protected against sudden, transient overvoltages. The
machine is designed to withstand 3 x 440 V voltage continuously. Ensure that voltage is kept
within this permissible limit, especially when the mains supply is provided by a combustion
engine generator. If the mains has under voltage (under approx. 300 V) or overvoltage (over
approx. 480 V) machine control stops operation automatically.
10
Loss of a phase in the mains supply
Loss of a mains power phase causes noticeably poor welding properties. In some cases the
machine won't start at all. Loss of a phase can be due to following:
• Blowing of mains supply fuse
• Defective mains cable
• Bad connection of mains power cable on machine terminal block or plug of machine.
