If the values of the duty cycle are exceeded, this
will trigger the overheat protection function, which
stops the machine until it is cooled down to normal
operating temperature. Repeatedly exceeding the
duty cycle values may lead to serious damage to the
machine.
3.2. CONNECTING THE DEVICE
•
Connecting the device to power must be performed
by a qualified person. In addition, a person with
required qualifications should check if the earthing
or electrical installation with protection system is in
line with the safety regulations and if they operate
correctly.
•
The device must be placed near the work station.
•
Connection of excessively long cables to the machine
must be avoided. Overly-long and thin wires will
cause voltage drops and malfunction of the device.
•
Single phase plasma cutters should be connected to
a socket equipped with a grounding pin.
PLEASE NOTE: THE DEVICE MAY ONLY BE USED IF THE
SYSTEM HAS A PROPERLY FUNCTIONING FUSE!

1.
Make sure that the On/Off switch on the back of the
device is in the "Off" position. Connect the device to
the power supply according to the information on
the nameplate.
2.
Make sure that the air pressure adjustment knob
is set to the minimum. Connect the compressed
air supply in accordance with the data given in the
technical data table.
3.
Connect the gun as shown in the figure above.
4.
Connect the earthing cable, taking care that the
clamp is securely attached to the workpiece. Always
tighten the cable connections to the device slightly
with a flat wrench (not included) and ensure that they
are properly and securely installed.

5.2. OPERATING THE PISTOL
Hold the pistol with the protective cap facing up and turn
the cap away from the gun. (The protective cap holds the
tip, the ceramic swirl ring and the electrode together).
Remove the cap, the ceramic swirl ring and the electrode.
Assemble the electrode, the ceramic swirl ring and the tip
back together. Replace worn parts if necessary. Put the
protective cap on the head of the pistol and screw it on
with your hand until it is snug. If any resistance is present
during this process, check the thread and the arrangement
of the items before resuming work.
NOTE
In case of some pistols with no reversible electrodes it is
necessary to tighten the electrode further by using a pair
of pliers in order to ensure a reliable electrical connection.

5.3. SETTING PARAMETERS FOR CUTTING
•
Set the electric current using the buttons (5) and (6)
on the control panel
•
Turn the knob (1) on the control panel to set the
compressed air pressure
•
Use the button (7) on the control panel to select the
gun mode, i.e.:
2T - short-term cutting. The cutting process begins
»
after pressing the button on the gun, releasing the
button ends cutting
4T- long-term cutting. Pressing the button on the
»
gun starts the cutting process, releasing the button
does not interrupt cutting. To finish the cutting
process, press and release the button on the gun
again.
•
Use the button (8) on the control panel to select the
operating mode of the device:
gas - only compressed air is extracted from the gun,
»
the gun is not electrically powered
work - compressed air is extracted from the gun and
»
an electric arc is initiated
•
To set the amount of time for which the air is to flow
from the gun after the cutting is finished, press and
hold the button (7) on the control panel. Use the
buttons (5) and (6) to set the time value in the range
provided in the technical data table.
5.4. USE
1.
Turn the On/Off switch to the „On" position. The
device will turn on and the current amperage value
will appear on the display.
2.
Set the air pressure value using the knob and other
parameters according to the description in point 5.3.
3.
Pull the trigger of the cutting gun, you should
hear the noise of the outgoing air. Depending on
the selected mode (gas/work), a pilot arc may also
appear. CAUTION: when firing the gun, always point
its outlet towards a safe place.
4.
Make sure that the cutting parameter values set are
suitable for the element which is being processed.
5.
You can start cutting the material.
6.
If the device overheats, the protection system will
activate. The LED (4) will light up on the control
panel. The device can only be restarted after cooling.
7.
After cutting, always turn the device off.
5.5. Periodic inspection
WEEKLY MEASURES: Verify the proper operation of the air
flow. Use compressed air to clean the ventilation cover of
dust and other contaminants.
EN
MAINTENANCE: Check the pistol for wear damage, cracks
or exposed wire sections. Replace or repair any such
defects before using the device. A heavily worn pistol tip/
nozzle contributes to reduced cutting speed, voltage drops
and crooked cuts. An indication of a worn pistol tip/nozzle
is an elongated or oversized nozzle opening.
6. DISPOSING OF PACKAGING
The various items used for packaging (cardboard, plastic
straps, polystyrene foam) should be kept, so that the device
can be sent back to the service centre in the best possible
condition in case of any problems!
7. TRANSPORTATION AND STORAGE
Avoid
shaking
or
dropping
the
device
during
transportation. Do not place objects on top of the device.
Store in a properly ventilated, dry space and without any
corrosive gases.
8. CLEANING AND MAINTENANCE
•
Always unplug the device and let the it cool
completely before cleaning and when the device is
not in use.
•
Use cleaners without corrosive substances to clean
each surface.
•
Dry all parts well before the device is used again.
•
Store the unit in a dry, cool place, free from moisture
and direct exposure to sunlight.
9. REGULARLY CHECK THE DEVICE
Check the device regularly for any signs of damage. If there
is any damage, please stop using the device. Please contact
the seller for repairs. What to do in case of a problem?
Please contact the seller and prepare the following
information:
