2.3 EXPLANATION OF THE TECHNICAL SPECIFICA-
TIONS LISTED ON THE MACHINE PLATE.
The equipment is manufactured according to these
international standards: IEC 60974.1-IEC 60974.3-IEC
60974.10 CL. A-IEC 61000-3-11-IEC 61000-3-12 (See note 2).
ransformer threephase-rectifier-
converter DC/DC (chopper).
N°.
Serial number, which must be indicated on
any request regarding the equipment.
Drooping characteristic.
P.A.C. Suitable for plama cutting.
torch type Welding torch type which can be used with
this equipment.
U0
Secondary open-circuit voltage (peak value).
X
Duty cycle percentage.
The duty cycle expresses the percentage of
10 minutes during which the equipment may
run at a certain current without overheating.
I2
Cutting current.
U2
Secondary voltage with I2 cutting current.
This voltage depends on the distance be-
tween nozzle and the workpiece.
If this dis-
tance increases also the cutting voltage
increases and the duty cycle X% may de

U1
Rated supply voltage.
3~ 50/60Hz 50- or 60-Hz three-phase power supply.
I1 max.
This is the maximum value of the absorbed
current.
l1 eff.
This is the maximum value of the actual cur-
rent absorbed, considering the duty cycle.
IP21
Degree of housing protection.
Degree
1
as the second digit means that this
device is not suitable for use outdoors.
S
This device is not suitable for use outdoors.
Suitable for use in high-risk environments.
NOTES:
1- The equipment has also been designed for use in envi-
ronments with a pollution rating of 3. (See IEC 60664).
2- This equipment complies with IEC 61000-3-11 provid-
ed that the maximum permissible system impedance
Zmax is less than or equal to 0,034 hom at the inter-
face point between the user’s supply and the public
system. It is the responsibility of the installer or user
of the equipment to ensure, by consultation with the
distribution network operator if necessary, that the
equipment is connected only to a supply with maxi-
mum permissible system impedance Zmax less than
or equal to 0,034 hom.
