Three-phase static transformer-rectifier fre-
quency converter.
N°. Serial number, (that must be indicated on
any request regarding the equipment).
Drooping characteristic.
Suitable for plasma 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 be-
tween nozzle and the workpiece. If this dis-
tance increases also the cutting voltage
increases and the duty cycle X% may de-
crease.
U1 Rated supply voltage.
1~ 50/60Hz 50- or 60-Hz single-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.
This device is not suitable for use outdoors.
S
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).

2.4 GASES: SPECIFICATIONS AND WORKING CON-
DITIONS
Following are described the specifications of the used
gases, with their purity and working conditions:
GAS
TITLE
USED
Clean, dry and oil
free as per ISO
8573-1: 2010
Air
standard. Class
1.4.2 (particulate-
water-oil) *
Argon 99.997%
* for the Class 1.4.2, the ISO 8573-1 2010 standard
requires:
≤ 20,000 solid particles per m3 of air
• Particulate:
with size between 0.1 and 0.5 µm;
≤ 400 solid particles per m3 of air with
size between 0.5 and 1.0 µm;
≤ 10 solid particles per m3 of air with size
between 1.0 and 5.0 µm.
• Water: the air pressure dew point must be below
or same as 3°C.
• Oil: the total oil concentration must be below
or equal to 0.1 mg per m3 of air.
3 INSTALLATION
3.1 UNPACKING AND PLACING
The use of proper lifting and moving equipments is
strongly recommended.
The power source draws air from the rear and makes it
leak from the front grilles. Place the generator in order
to have a large ventilation area and keep a distance of at
least 1 m from any walls.
Do not stack the power source, nor overlay objects on it.
Place the power source on a substantially flat surface
and with a slope of not more than 10 °.
3.2 WELDING TORCH ASSEMBLY
After introducing the mobile fitting M into the protection
K, insert it onto the fixed fitting J, by screwing down the
fitting collar M to avoid air leaking that may jeopardize a
good operation.
Do not dent the contact tip, do not bend the mobile
fitting M pins.
Screw the protection K onto the panel.
3.3 START-UP
Only skilled personnel should install the machine.
All connections must be carried out according to
current regulations, and in full observance of safety
laws (CEI 26-36/IEC 60974-9 standards).
