Nominal supply voltage.
50- or 60-Hz three-phase supply.
Max. absorbed current at the corresponding
current I2 and voltage U2.
This is the maximum value of the current
actually absorbed, taking the duty cycle into
account. This value usually corresponds to the
capacity of the fuse (delayed type) which is to
serve as protection for the equipment.
Degree of protection for the housing. Grade 3
as the second digit means that this equipment
is suitable for outdoor use.
Suitable for use in high-risk environments.
NOTES: The machine is also designed to be
used in environments with a pollution level of 3.
2.5 THERMAL PROTECTION
This Inverter is protected by a thermostat When the
thermostat is triggered, the machine no longer supplies
power but the power, but the fan continues to operate.
The yellow LED (B) lights up to indicate that the
thermostat is indicate that the thermostat is activated.
Do not switch off the welding machine until the LED is
extinguished. See 6.1.1. for possible solutions.
2.6 UPDATE
The machine must be installed by qualified person-
nel. All connections must be made in accordance
with the current safety current safety standards
and in full compliance with respect of the safety
regulations (see CEI 26-23 - IEC TS 62081).
Connect the power supply cable (fig. 2): the yel-
low/green wire must be connected to an efficient
earth connected to an efficient earth contact on the
system. The other wires must be connected to the
power supply cable by means of a switch that is as
close as possible to the cutting area, so that it can
be quickly be switched off in an emergency. The
capacity of the switch or of the fuses in series
with the switch must be equal to the current I1 eff
absorbed by the machine. The absorbed current
I1 eff can be determined by reading the technical
specifications indicated on the machine under the
available supply voltage U1. Any extension cables
must be of the correct size for the current I1 max.
absorbed.
2.6.1 GENERATORS
They must have an electronic voltage regulator, a
power equal to or greater than 7.5 kVA and must
not supply a voltage greater than 440V.
3. USE (see Fig. 2)
Turn the machine on with the switch H. The warning
lamp A lights up to indicate that the machine is on.
Connect the grounding terminal to the workpiece.
The cutting circuit may not be intentionally brought
into direct or indirect contact with the protective
wire, except in the workpiece. If the workpiece is
intentionally grounded using the earth wire, the
connection must be as direct as possible, using a
wire of at least the same size as the return wire of
the cutting current, and connected to the workpiece
at the same point as the return wire using the
return terminal or a second ground terminal placed
in the immediate vicinity. All precautions must be
taken to avoid stray currents. Use the F button to
select the cutting current. Use a cutting sleeve with
a diameter of 0.95. Ensure that the ground clamp
and the workpiece have good electrical contact,
especially with painted, oxidised or insulated sheet
metal. Do not connect the ground clamp to the
part of the material to be removed. Press the torch
handle to ignite the arc. If cutting does not start
within 2 seconds, the arc goes out; press the trigger
again to reignite the arc. Keep the torch upright
during cutting. When you have finished cutting and
released the trigger, air will flow from the torch for
approximately 100 seconds to allow the torch to
cool. It is advisable not to turn the machine off until
this cooling period has been completed. If you need
to make holes or start cutting from the centre of
the workpiece, hold the torch at an angle and slowly
straighten it out so that the cutting sleeve does
not spray molten metal (see Fig. 1). This should be
done when making holes in pieces over 3 mm thick.
For thicknesses over 10 mm, the material must be
perforated before cutting. For making circular cuts,
we recommend using the special compass that is
available on request. It is important to remember
that the use of the compass may make it necessary
to apply the starting technique described above
(see Fig. 1). Do not leave the pilot light on when it
is not needed, to avoid unnecessary consumption
of electrode, swirl ring or cutting sleeve. Switch off
the machine when the job is finished.
