    2.5.3 Cable positions for multiple machine configurations
    When using two or more FastMig X 350MV 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 350MV unit should be connected close to each other
    and away from other units’ cables (see the pictures below).

    EN
    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 350MV
    power sources can be connected to the mains supply of 220...230 V 3~ or 380...440 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.

    *) In cables of S type there is a protective grounding conductor coloured green-yellow.
    Generator use
    If no mains connection is available, you can use FastMig X 350MV on a generator. The
    minimum recommended generator output is 35 kVA. The greater the output, the more stable
    is the FastMig X 350MV operation.

    2.5.5 Cables
    Kemppi always recommend the use of high quality copper cables with a suitable crosssectional area. Cable size should be selected depending on the intended welding application.
    50 mm² copper cables may be used for low duty work in basic or synergic 1-MIG. However,
    using pulsed MIG/MAG process, longer cables, or higher welding power increase the voltage
    loss, and therefore smaller cross sectional interconnection cables and earth return cables will
    restrict the welding performance of your machine.
    Recommended cross-sectional area of FastMig X 350MV cables: 70 – 95 mm².
    The enclosed table shows typical load capacities and voltage loss values of rubber insulated
    copper cables for duty cycles 100%, 60% and 30%, when ambient temperature is 25 °C and
    the cable temperature is 85 °C.

    Do not overload the cables due to voltage losses and heating.
    NOTE! Always check the serviceability of the earth return cable and clamp. Ensure the metal
    surface to which the cable is connected is clean from metal oxide or paint. Check the connector to
    the power source is fastened correctly.

    EN

    2.5.6 Interconnection with wire feeder
    Kemppi provide a choice of interconnection cable sets for different environments. Only
    materials that meet the demands of Kemppi's international markets are used in their
    construction.
    Used correctly, Kemppi cable sets ensure high welding performance and serviceability.
    Before use, always ensure the cable set is in good condition and that connectors are correctly
    fastened. Loose connections reduce welding performance and may result in damage to
    connectors due to heating effects.
    For correct connection and configuration of cable sets, please refer to schematic drawings in
    section 2.5 of this manual.
    NOTE! FastMig X 350MV power sources are designed to be used with WFX wire feed units.

    OPERATION CONTROL

    3.1 Main switch I/O
    When you turn the on/off switch into position I, the pilot warning lamp is illuminated and the
    machine is ready for use. Always turn the machine on and off with the power source mains
    switch. Never use the mains plugs as a switch.

    3.2 Pilot lamps
    The pilot lamps of the machine report its operational state:
    When the green pilot lamp is on, it indicates that the machine is switched on and ready for
    use.
    When the orange pilot lamp is on, it indicates that the machine is overheated due to higher
    than normal working loads that exceed the rated duty cycle. The cooling fan will continue to
    run and cool the machine down. When the lamp is off the machine is again ready to weld.

    3.3 Operation of cooling fan

    EN

    FastMig X 350MV power sources incorporate two simultaneously operating fans.
    • The fan is started momentarily when the main switch is turned into position I.
    • The fan will start during welding as the machine reaches operational temperature, and
    it will run for 1 to 10 minutes after the welding has stopped, depending on the welding
    cycle completed.

    3.4 Manual Metal Arc Welding
    MMA electrode welding is a standard feature of FastMig X 350MV power source. To use it you
    need to connect the electrode holder to the power source positive pole (+) and select the
    MMA welding mode either from the power source or from the wire feeder:
    • In power source control panel, select MMA/CC/CV Mode from the main menu list.

    4.5 Arc voltage display

    EN

    FastMig X 350MV is capable of measuring and showing the voltage close to the welding arc.
    By taking this feature into use you don't need to be concerned about the voltage losses in
    welding cables anymore. With this feature you are only required to set the voltage for the arc
    before welding and after welding you can see the voltage close to the arc.
    In order to use the arc voltage feature, follow these steps:
    1. After setting up the welding equipment for the first time, connect the voltage sensing
    cable to the welding piece and the measurement cable between the wire feeder and the
    power source.
    2. If you are using a sub-feeder, enter the length of the sub-feeder to the SubFeederLength
    parameter.
    3. Set the welding parameters according to your application. Note that the set voltage
    when using 1-MIG, MIG and WiseThin+ welding processes means always the voltage in
    the arc despite of ArcVoltage setting.
    4. Weld with 1-MIG, MIG or with Pulse MIG for at least 5 seconds. During that time the
    welding machine calibrates itself for the welding cable length in question. Calibration
    values are stored into the welding machine, therefore this calibration is required only
    once after installing the welding machine package.
    5. If you want to see arc voltage in panels during and after welding, turn the ArcVoltage
    setting to ON. Dot after voltage value in XF 37 or XF 38 panel means that showed value is
    arc voltage. In the weld data after welding in X 37 panel 'AVol' means also the arc voltage.
    6. Voltage sensing cable can be removed after the calibration procedure, but it is
    recommended to use it always.
    NOTE! Steps 1-3 should be repeated every time, when the length of the welding or grounding cable
    is changed.

    4.6 Welding software delivery profile
    Connected to Kemppi's WFX wire feed unit, FastMig X 350MV power source makes a very
    efficient, multi-process welding system.

    OPERATION DISTURBANCES
    Should you experience a malfunction from your machine, please consult the basic
    troubleshooting text above first, 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 or overvoltage machine control stops
    operation automatically.

    EN

    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.

    7.

    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.

    7.1 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 filler wire you are using, and that their
    pressure adjustment is correct.

    7.2 Periodic maintenance
    NOTE! Periodic maintenance should only be carried out by a suitably qualified 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 profiles.
    Do not use pressure washing devices.
    Only an authorized trained electrician should carry out repairs to Kemppi machines.

    EN
