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-
crease.

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.

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 0,044 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-
