Do not remove or short-circuit the safety devices.
Use only original parts.
Always replace any damaged parts of the machine with original materials.
Do not run the machine without its housings. This would be dangerous to the ope-
rator and anyone else in the work area, and would prevent the machine from being
cooled properly.
3.3 Explanation of technical specification
EN 60974.1
The machine has been built according to this European stan-
dards
EN 50199
EN 50192
N............
Serial number. Always indicate this for any request
Single phase static transformer-
rectifier frequencyconverter, inverter.
Drooping characteristic.
Suitable for plasma cutting.
TORCH TYPE..
Type of torch that may be used with this machine.
U0
Secondary open-circuit voltage Peak value.
X%
Percentage duty cycle.
The duty cycle expresses the percentage of 10 minutes for
which the machine may work at a certain current I2 and
voltage U2 without overheating.
I2
Cutting current.
U2
Secondary voltage at cutting current I2.
This voltage in measured when cutting with the gas nozzle
in contact with the work piece.If this distance increases,
the cutting voltage also increases and the duty cycle X%
may drop.
U1
Main supply voltage
1~50/60Hz
Single phase 50/60 Hz power supply
