2. Safety devices
This system comes equipped with the following safety devices: (see table 1 )
Overload cut out: to avoid overload while cutting.
Pneumatic: located on the torch inlet to prevent low air
pressure.
Electrical:
* In the event of the main voltage is too low or too high.
* In the event of torch maintenance with main power on. In this event all cutting
function are prevent

Single phase static transformer rectifier
frequency converter, inverter.
Three phase static transformer rectifier
frequency converter, inverter.
Drooping characteristic.
Suitable for plasma cutting.
Type of torch that may be used with this machine.
Secondary open-circuit voltage Peak value.
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.
Cutting current.
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.
Main supply voltage
Single phase 50/60 Hz power supply, treephase 50/60Hz
Primary supply current at the corrispondind cutting current
I2 and cutting voltage U2 .
Housing protection rating.
