E) SUGGESTED CUTTING SPEED (only in mechanized cutting):
Once the thickness and the kind of material to be cut are specified, the machine displays the suggested cutting speeds, the value indicated after the letter
"q" (Pict. 4 Ref. E) is the suggested speed for a quality cut, the value indicated alter the letter "m" (Pict. 4 Ref. E), on the contrary, is the suggested speed for
production in quantity.
F) SUGGESTED NOZZLE:
This icon (Pict. 4 Ref. F) shows the diameter of the nozzle to be used, the value is indicated on the basis of the cutting current.
G) CUTTING CURRENT:
Selecting this icon (Pict. 4 Ref. G) it is possible to modify the cutting current, in automatic mode the machine will suggest a cutting current accordingly to the

1.3. SAFETY DEVICES

This system comes equipped with the following safety
devices:
be
Overload cut-out:
To avoid overloads.
Pneumatic:
Located on the torch inlet to prevent low air
pressure. If the icon appears on the display, it means that
the pressure has temporarily gone below 3.2 ÷ 3.5 bar.
Electrical:
Located on the torch body, to prevent hazardous voltages
from occurring on the torch when, swirl ring, electrode or
nozzle holder are replaced;
 Do not remove or short-circuit the safety devices.
 Use only original spare parts.
