LUBRICANT

RECOMMENDED OILMOSA recommends selecting AGIP engine oil.Refer to the label on the motor for the recommendedproducts.

REFUELLING AND CONTROL:Carry out refuelling and controls with motor at levelposition.1. Remove the oil-fill tap (24)2. Pour oil and replace the tap3. Check the oil level using the dipstick (23); the oil

level must be comprised between the minimumand maximum indicators.

Please refer to the motor operating manual for therecommended viscosity.

AIR FILTER

Check that the dry air filter is correctly installed andthat there are no leaks around the filter which couldlead to infiltrations of non-filtered air to the inside ofthe motor.

It is dangerous to fill the motor with too much oil,as its combustion can provoke a sudden increasein rotation speed.

ATTENTION

BATTERY WITHOUT MAINTENANCE

Connect the cable + (positive)to the pole + (positive) of thebattery (after having takenaway the protection), byproperly tightening the clamp.

Check the state of the batteryfrom the colour of the warning light which is in theupper part.

- Green colour: battery OK- Black colour: battery to be recharged- White colour: battery to be replacedDO NOT OPEN THE BATTERY.

FUEL

Do not smoke or use open flames duringrefuelling operations, in order to avoidexplosions or fire hazards.Fuel fumes are highly toxic; carry outoperations outdoors only, or in a well-ventilated environment.Avoid accidentally spilling fuel. Cleanany eventual leaks before starting upmotor.

ATTENTION

Refill the tank with good quality diesel fuel, such asautomobile type diesel fuel, for example.

For further details on the type of diesel fuel to use,see the motor operating manual supplied.

Do not fill the tank completely; leave a space ofapprox. 10 mm between the fuel level and the wallof the tank to allow for expansion.

In rigid environmental temperature conditions, usespecial winterized diesel fuels or specific additivesin order to avoid the formation of paraffin.

COOLING LIQUID

Remove the tap and pour the liquid coolant into theradiator; the quantity and composition of the liquidcoolant are indicated in the motor operating manual.Replace the tap, ensuring it is perfectly closed.After refilling operations, allow the motor to run fora brief time and check the level, as it may havediminished due to air bubbles present in the coolingcircuit; restore the level with water.To replace the liquid coolant, follow the operationsdescribed in the motor operating manual.

Do not remove the radiator tap with themotor in operation or still hot, as the liquidcoolant may spurt out and cause seriousburns. Remove the tap very carefully.

GROUNDING CONNECTION

The grounding connection to an earthed installationis obligatory for all models equipped with adifferential switch (circuit breaker). In these groupsthe generator star point is generally connected tothe machine’s earthing; by employing the TN or TTdistribution system, the differential switchguarantees protection against indirect contacts.In the case of powering complex installationsrequiring or employing additional electrical protectiondevices, the coordination between the protectiondevices must be verified.For the grounding connection, use the terminal(12); comply to local and/or current regulations inforce for electrical installations and safety.

TIG MODEContact starting TIGThis position is specifically for TIG welding. To cre-ate the arc simply place the tip of the TIG electrodeon the piece that requires welding then gently movethe tip away. The arc starts automatically and at thesame time the welding current rises to the presetvalue, first using the welding current adjustmentknob which is on the lower part of the control panel.The welding current can be adjusted continuouslyfrom a minimum of 10 A to a maximum whichdepends on the power of the machine 400 A, 500 A,600 A.

Inversion of polarity (Optional, available onrequest)In order to invert polarity, press the switch on theremote control unit.By selecting “inversion” the “ON” LED switches offand the voltage at the welding socket becomeszero. The power contactor is witched inside theelectrical box and the voltage reappears at thewelding sockets. The “ON” LED switches back onat the same time.The “Invert polarity” LED on the front panel near thewelding current adjuster switches on .You cannot invert polarity in “MIG/MAG” mode.

PROTECTIONSThe Welding Digital Control features 3 protectionsfor the control and chopper.

1) “ON” LED blinkingWhen the engine of the welder isstarted the control unit automatically

goes to the stand by mode for few istants (stand-byLED on) and performs a self-diagnosis of the currentsensor connector and power source voltage + 15V;than the last process is loaded (on led turned ON).In case of malfunction the “ON” LED blinks.

2) Red LED blinkingThe chopper has a thermal protection,which intervenes in case the operating

temperature exceeds 85°C.If the protection intervenes, the red LED begins toflash and the welding current/voltage goes to zero.In this case do not switch off the welder, since thealternator fan will help cool down the chopper morequickly.After a few minutes, the LED will automaticallyswitch itself off and the welding voltage/current willonce again be available at the plugs.

3) Red LED continuously litIf an anomalous current is detected inthe chopper, the control blocks theconversion immediately, the output

welding current/voltage goes to zero and the redLED lights up. To reset everything, it is necessaryto switch off the machine.

If the protections 1) and 3) should intervene, it isbest to immediately contact the nearest authorisedService Centre.

DIGITAL INSTRUMENTS(Optional, available on request)Two digital instruments showed the operating valueof welding current and welding voltage.

For EP1 version it is compulsory to acceleratethe engine manually.

WARNING

STICK MODE (Electrode)Features C.C. (Constant Current)There are three stick modes which featureincreasing “arc forces” so that the arc has differentlevels of penetration according to the electrodeand/or welding position.

MIG/MAG MODE (continuous wire)Features C.V. (Constant Voltage)All wire type welding processes can be carried out,naked or coated.The voltage can be adjusted using the same knobwhich adjusts the current in STICK mode.Adjustment is continuous and goes from a minimumof 15 V to a maximum of 36V, 40 V.

Optional remote control

The welding current can also be set from a distanceusing the optional remote control. Once the remotecontrol is connected to the connector (X1), thecurrent is controlled by the remote control. To returnto front panel control remove the connector.

Optional VRD program (Voltage Reduction DeviceVRD)When you choose the program stick or stick arcforce the Open Circuit Voltage (OCV) go up, redlight switch ON and green light switch OFF, batonly for about 3”, than the OCV go down, greenlight switch ON and red light switch OFF, about11V and stop there, until the welder start welding.When you make a short circuit with the stick theOCV immediately go up, so you can start to welding.

GENERATION IN AC (ALTERNATING CURRENT)Make certain of the efficiency of the groundconnection (12) - See page M20 -.Position the G.F.I. switch to ON.Voltage is now immediately available to the AC

sockets.Verify that the voltmeter displays the nominal voltagevalue + 10%.Connect the electric devices to be powered to theAC sockets, using suitable plugs and cables ingood condition.

It is strictly forbidden to connect the group tothe public mains and/or to any other sourceof electric power.

WARNING

Verify that the electrical characteristics (voltage/frequency/power) of the device being powered arecompatible with those of the generator.Low frequency and/or voltage can irreparablydamage some electrical devices.Verify that the ground lead of the electrical appliance/tool to be powered is correctly connected to theterminal of the plug. For double insulation devices with the symbol , the plug’s ground terminal does not need

to be grounded.

THERMAL PROTECTIONThe monophase outputs are protected againstoverloads by the thermal protection (59B).When the rated current is exceeded, the protectionintervenes to cut off the voltage to the AC socket.. Note: the intervention of the thermal protection isnot instantaneous, but reacts accordingto an overcurrent/time characteristic, whereby thegreater the overcurrent the quicker the intervention.In case of intervention by the protection device,verify that the total power for the loads connecteddoes not exceed the declared rating and decreaseif necessary. Disconnect the loads and wait a fewminutes to allow the thermal protection to cool down.

Before resetting by pressingthe central button and thenconnect the load again.If the protection should

intervene again, replace it with another one withmatching intervention current specifications and/orcontact the Service Department.. Note: do not forcibly hold the central button of thethermal protection device to prevent its intervention,as this could irreparably damage the unit’salternator. Note: the three phase output does not require

any protection against overcurrents, since it usesa self-protecting asynchronous type alternator.

GROUND FAULT INTERRUPTOR SWITCHThe high-sensitivity ground fault interruptor switch[G.F.I.] (30mA) (D), guarantees protection againstindirect contacts due to faulty ground currents .When the G.F.I. switch picks up a faulty groundcurrent that is higher than 30mA, it intervenes byimmediately cutting off voltage to the AC sockets.

In case of intervention by this protectiondevice, reset the G.F.I. switch by movingthe lever to the ON position. In case ofanother intervention, verify that there areno faults in the tools connected, orreplace the G.F.I. switch with another

one of matching specifications and/or contact theService Department.

Notes: Verify the operation of the G.F.I. switchat least once a month by pressing the TEST button.The generator must be running and the G.F.I. leverin the ON position.

SIMULTANEOUS USEThe welder’s alternator permits the simultaneoususe of auxiliary power and welding current. Theauxiliary power available to the AC plugs (15)diminishes as the welding current drawn increases.The table on page M52 TECHNICALSPECIFICATIONS shows the amount of auxiliarypower available as the welding current varies.

COMBINED USEThe output available from the various auxiliary powersockets is limited, not only by the declared output ofthe unit but also by the capacity of each individualsocket.

When the RC1 is not used, it is necessary to disconnectthe multipole connector

ATTENTION

Is it possible to connect the RC1, to all DSP engine drivenwelders.

The remote control RC1, which regulates the welding currentin the CC mode and the welding voltage in the CV mode, isconnected to the front panel by means of a multipole connector.

When the remote control is connected to the remote controlconnector (8), it is functional and automatically excludes thefront panel regulation. The remote control can also beconnected to the connector on the wire feeder front panel butin this case it is necessary to switch the wire feeder commutatorso it can operate.

The polarity inverter (64A), if installed, can be operated fromthe remote control.

Maintenance operations also include machine cleaningoperations when carried out on a periodic basis outsideof the normal work cycle.

The repairs cannot be considered among themaintenance activities, i.e. the replacement of partssubject to occasional damages and the replacement ofelectric and mechanic components consumed in normaluse, by the Assistance Authorized Center as well as byMOSA.

The replacement of tires (for machines equipped withtrolleys) must be considered as repair since it is notdelivered as standard equipment any lifting system.

The periodic maintenance should be performed accordingto the schedule shown in the engine manual. An optionalhour counter (M) is available to simplify the determinationof the working hours.

THE ENGINE PROTECTION NOT WORK WHEN THEOIL IS OF LOW QUALITY BECAUSE NOT CHARGEDREGULARLY AT INTERVALS AS PRESCRIBED INTHE OWNER’S ENGINE MANUAL.

NOTE

IMPORTANTIn the maintenance operations avoid thatpolluting substances, liquids, exhausted oils,etc. bring damage to people or things or cancause negative effects to surroindings, healthor safety respecting completely the laws and/or dispositions in force in the place.

WARNING Have qualified personnel do maintenance and troubleshooting work. Stop the engine before doing any work inside the machine. If for any

reason the machine must be operated while working inside, payattention moving parts, hot parts (exhaust manifold and muffler,etc.) electrical parts which may be unprotected when the machineis open.
