2.3 SAFETY SYMBOLS
This machine comes with the following safety symbols.
Overload protection:
To prevent overloading. This can be seen by
the LED C (see fig. 2) lighting up
continuously.
Pneumatic:
Located on the torch inlet to prevent low air
pressure. The LED D (see Fig. 2) lights up
when it is activated. It means that the
pressure is temporarily below 3.2÷3.5 bar.
Electric:
Located on the torch body to prevent dangerous
voltages from being applied to the torch when,
swirl ring, electrode or cutting attachment is
replaced.
• Do not remove or short-circuit the safety
devices.
• Only use original spare parts.
• Always replace damaged parts of the machi-
ne with original materials.
• Do not operate the machine without the
• housing. This would be dangerous for the
operator and others in the working area,
and would prevent the machine from being
properly cooled.
2.4 EXPLANATION TECHNICAL
SPECIFICATIONS PLATE
IEC 60974-1 The equipment has been built in
accordance with these standards.
IEC 60974-10 standards.
IEC 60974-7
Three-phase static transformer rectifier
frequency converter.
Descending.
Suitable for plasma cutting.
That with this machine can be used machine to
form a safe system.
Secondary open-circuit voltage.
Duty cycle percentage.
The duty cycle percentage indicates the
percentage of 10 minutes during which the
welding machine machine is allowed to run at a
given current voltage U2 without overheating.
Cutting current.
Secondary conventional voltage with
welding current I2 . This voltage depends on
the distance between the cutting sleeve and
the workpiece. If this distance increases, the
voltage increases and the duty cycle X% can be
reduced.
Power indicator light.
Safety lock LED indicator;
this lights up when hazardous
working conditions are present
are present (see section 6.1.1).
Thermostat LED.
“Insufficient air pressure” LED.
Connection for cutting torch.
Rotary knob for adjustment
of the cutting current.
Connection for earth cable.
On/off switch.
Power plug.
