C) Four flashes followed by a 2-second pause mean
there is a short circuit in the torch (e.g., between elec-
trode and nozzle) or between the positive and nega-
tive in the Plasma Cutter. Switch off the machine and
remedy the problem if this is located in the torch; oth-
erwise contact the technical service.
D) On steady means the start button has been pressed
when the machine was on. Release the button.
Moreover, the torch has an electric safety device on the
torch body, to prevent hazardous power voltages when
the nozzle, electrode, swirl ring or nozzle holder are re-
placed.
• 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 torches type CP41 C.
• 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 THE TECHNICAL SPECIFICA-
TIONS LISTED ON THE MACHINE PLATE.
The equipment is manufactured according to these
international standards: IEC 60974.1 - IEC 60974.7 -
IEC 60974.10 CL. A.
N°........ Serial number.
Always indicate this for any request regard-
ing the machine.
Static transformer single-phase-rectifier-
frequency converter.
Drooping characteristic.
P.A.C. Suitable for plama cutting.
TORCH TYPE Type of torch that may be used with this
machine.
U0 Secondary open-circuit voltage (peak value).
X Duty cycle percentage.
The duty cycle expresses the percentage of
10 minutes for which the machine may work
at a certain current I2 and voltage U2 with-
out 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 distance increases also the cutting
voltage increases and the duty cycle X%
may decrease.
U1 Rated supply voltage.
1~ 50/60Hz 50 or 60Hz single-phase power supply.
I1 max. Max. absorbed current at the corresponding
current I2 and voltage U2.
l1 eff. This is the maximum value of the actual
curent absorbed, considering the duty cy-
cle.This value usually corresponds to the ca-
pacity of the fuse (delayed type) to be used
as a protection for the equipment.
IP23S Housing protection rating.
