Explanation of the technical specifications listed on the machine plate.

Three-phase static transformer-rectifier frequency converter.
N°. Serial number, (that must be indicated on any request regarding the equipment).
Drooping characteristic.
P.A.C. Suitable for plama cutting.
torch type Welding torch type which has to be used with this equipment to correctly achieve a safe system.
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 I2 and U2 voltage without overheating.
I2 Cutting current.
U2 Secondary voltage with I2 cutting current.
This voltage depends on the distance between nozzle and the workpiece. If this distance increases
also the cutting voltage increases and the duty cycle X% may decrease.
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
l1 eff. This is the maximum value of the actual current 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.
This device is not suitable for use outdoors.

NOTES:
1-The device has been designed for use in environments with a pollution rating of 3. (See IEC 60664).
2-This device complies with standard IEC 61000-3-12 provided that the system's maximum permitted impedance
Zmax is less than or equal to 98 mΩ (Item No 334) or 66 mΩ (Item No 336) or 22 mΩ (Item No 337) at the interface
point between the user's system and the mains. The fitter or the device user are responsible for connecting the
device to a power supply with a maximum permitted system impedance Zmax less than or equal to 98 mΩ (Item
No 334) or 66 mΩ (Item No 336) or 22 mΩ (Item No 337).
