Micro 300 is a compact and rugged three-phase, synergic inverter
power source for MIG/MAG, MMA and TIG Lift welding.
Easy to transport, only 22kg , it is the best option for maintenance and
repair on fi eld, shipyard and off -shore operations.
Polarity change allows welding with self shielded wires.
Innovative unique HAC (Hybrid Arc Control) supplies a soft and very
stable MIG-MAG arc with excellent weld bead quality and minimal
spattering in any working conditions.
3T Mode allows both Hot Start and Crater Filler current setting, for
optimal penetration at start and crater fi lling at bead’s end.
Additional parameters, Motor Slope, Soft Start, Burn Back and Post
Gas are included for perfect arc ignition and optimum wire cutting at
the end of welding.
Microprocessor, inverter technology, digital displays, synergic curves
and memory locations for customized welding parameters assure
complete welding process repeatability. The inductance can be
adjusted electronically by means of the user interface in order to
optimize the arc.
A perfect wire feeding is guaranteed thanks to a 4-rolls motor drive
included in Micro 300.
The welding modes and procedures available are those indicated in
the table.

4.1 CONNECTIONS TO THE ELECTRICAL MAINS
NETWORK
The characteristics of the mains power supply to which the equipment
shall be connected are given in the section entitled “technical data” on
page 23.
The machine can be connected to motorgenerators provided their
voltage is stabilised.
Connect/disconnect the various devices with the machine switched off.
4.2 PREPARING FOR MMA WELDING
1.Turn the switch “OFF” (equipment switched off).
2.Connect the power cable to the power outlet.
3.Choose the electrode based on the type of material and thickness
of the workpiece to be welded.
4.Insert the electrode in the electrode holder.
5.Connect the plug of the electrode holder clamp to the welding socket
on the basis of the polarity required by the type of electrode in
question.
6.Connect the plug of the ground clamp to the welding socket on the
basis of the polarity required.
7.Connect the earth clamp to the workpiece being processed.
WARNING!
ELECTRIC SHOCK HAZARD!
Read the warnings highlighted by the following symbols in the
“General prescriptions for use”.
8.Set the welding power source ON/OFF switch to “I” (unit powered).
9.Use the selector in the spool housing to select MMA welding mode.
10. Set the required welding parameter values on the user interface.
11. The system is ready to start welding.

energized).
2.Plug the power cable plug into a mains socketoutlet.
3.Connect the gas hose from the welding gas cylinder to the relative
socket.
4.Open the cylinder gas valve.
5.Choose the electrode on the basis of the type of material to be
welded and the thickness of the workpiece.
6.Insert the electrode in the TIG torch.
7.Connect the TIG torch plug to the EURO TORCH welding socket
8.Connect the plug of the polarity selector cable to the welding socket
on the basis of the polarity required.
9.Connect the plug of the ground clamp to the welding socket on the
basis of the polarity required.
10. Connect the earth clamp to the workpiece being processed.
11. Set the welding power source ON/OFF switch to “I” (unit powered).
12. Use the selector in the spool housing to select TIG welding mode.
13. Select the torch trigger procedure on the user interface.
14. Press the torch trigger with the torch well clear of any metal parts.
This serves to open the gas solenoid valve without striking the
welding arc.
15. Use the flow control valve to adjust the flow of gas as required
while the gas is flowing out.
16. Set the required welding parameter values on the user interface..
17. The system is ready to start welding.

4.4 PREPARING FOR MIG/MAG WELDING
WIRE SPOOL POSITIONING
1.Open the unit side door to gain access to the spool compartment.
2.Unscrew the cap of the spool holder.
3.If necessary, fit an adapter for the wire spool.
4.Choose the wire on the basis of the workpiece thickness and
material type.
5.Fit the spool in the spool holder, ensuring it is located correctly.
6.Adjust the spool holder braking system by tightening/loosening the
screw in such a way that the wire feed force is not excessive and
when the spool stops rotating no excess wire is released.
7.Refit the plug.
POSITIONING THE WIRE IN THE WIRE FEEDER
1.Lower the wire feeder pressure devices.
2.Raise the wire feeder pressure arms.
3.Remove the protective cover.
4.Check that the feed rolls are suitable for the wire gauge
§ 15.2
The diameter of the roll groove must be compatible with the
diameter of the welding wire
The roll must be of suitable shape in relation to the composition of
the wire material
The groove must feature a "U" profile for soft materials
(Aluminium and its alloys, CuSi3).
The groove must be "V" shaped for harder materials (SG2-SG3,
stainless steels)
Rolls with a knurled groove profile are available for flux-cored
wire.
5.Feed the wire between the wire feeder rolls and insert it into the
MIG/MAG TORCH connector plug.
Make sure the wire is located correctly in the roll grooves.
6.Close the wire feeder pressure arms.
7.Adjust the pressure system so that the arms press the wire with a
force that does not deform it while also ensuring constant feed
rate without slipping.
8.Refit the protective cover.
9.Close the spool compartment door in the side of the unit.

(§ 10.1.2) H.S.
This parameter aids electrode melting at the time of arc striking.
Consequences of a higher value:
Easier arc strike
Increased spatter at welding start
Increase of strike area
Consequences of a lower value:
More difficult arc strike
Less spatter at welding start
Smaller strike area

Calculated as a percentage of the programmed wire feed rate
Crater-Filler
1/80/200
(%)
2nd level Menu
(§ 10.3.2)
C-F
This parameter serves to obtain a uniform deposit at the end of the welding process to fill the crater with a
reduced wire feed rate to facilitate the deposition of filler material.
By keeping the torch trigger pressed during the 3rd time, the wire feed rate is reduced (crater filler speed)
thereby ensuring optimal crater filling, until the postgas time is started by releasing the torch trigger (4th
time).
Consequences of a higher value:
-Difficult crater filling (values greater than 100%)
Consequences of a lower value:
-Cold welding (values close to 1%)

This parameter helps to avoid electrode sticking during welding
Consequences of a higher value:
Fluidity during welding
Welding arc stability
Greater electrode fusion in workpiece
More welding spatter
Consequences of a lower value:
The arc is extinguished more easily
Less welding spatter

Consequences of a higher value:
More effective pickling (improved appearance of workpiece at the end of the welding pass).
Higher gas consumption.
Consequences of a lower value:
Lower gas consumption.
Oxidation of electrode tip (more difficult arc strike).
