B) 115V Power supply: during start-up, the machine
remains blocked (LED N lit) if the voltage is below 100V.
After start-up, the machine runs at as low as 90V.
• Do not remove or short-circuit the safety devices.
• Use only original spare parts.
• Always replace any damaged parts of the machine
with original materials.
• Use only CEBORA torches type CP40.
• Do not run the machine without its housings. This
would be dangerous to the operator and anyone else
in the work area, and would prevent the machine from
being cooled properly.
2.3 EXPLANATION OF TECHNICAL SPECIFICATIONS
EN 60974.1 The machine has been built according to
EN 50199 this European standards.
EN 50192
N°..................... Serial number.
Always indicate this for any request regar
ding the machine.
....... Single-phase static transformer-rectifier
frequency converter.
................... Drooping characteristic.
.................Suitable for plasma cutting.
T ........Type of torch that may be used with this
ORCH TYPE
machine.
U . PEAK........Secondary open-circuit voltage. Peak
0
value.
X....................... Percentage duty cycle.
The duty cycle expresses the percentage
of 10 minutes for which the machine may
work at a certain current I
U without overheating.
2
I ....................... Cutting current.
2
U ..................... Secondary voltage at cutting current I
2
This voltage is measured when cutting
with the gas nozzle in contact with the
workpiece.
If this distance increases, the cutting
voltage also increases and the duty
cycle X% may drop.
U ......................Rated supply voltage
1
1~ 50/60Hz....... 50- or 60-Hz single-phase power supply.
The machine is equipped with automatic
voltage change.
I ....................... at the corresponding
1
cutting current I
IP23.................. Housing protection rating.
Class 3 as the second digit means that
this machine is suitable for working out
doors in the rain.
S
.................... Suitable for working in hazardous envi-
ronments.
NOTE: The machine has also been designed for use in
environments with a pollution rating of 3. (See IEC 664).
