•
The plasma cutting station is to be located away
from flammable surfaces.
•
Before starting plasma-cutting, get rid of flammable
or explosive objects, such as propane-butane
lighters or matches.
•
Observe safety and OHS regulations applicable
to welding work and ensure the work station is
equipped with an appropriate fire extinguisher.
The flame and the working circuit are energized if
the electric power supply is activated. The input and
internal circuit of the device are also energized if the
electric power supply is activated.
ELECTRIC SHOCK IS HAZARDOUS FOR LIFE AND
HEALTH
•
Do not touch energized elements.
•
Wear dry, insulated gloves without any holes, as well
as suitable protective clothes.
•
Put insulation mats or other insulation coatings
on the floor, which should be sufficiently large to
prevent the body from touching the workpiece or
the floor.
•
Do not touch the electric arc if it touches the
workpiece or the floor.
•
Before operating, cleaning or replacing the electrode,
disconnect the electrical power supply.
•
Before the installation or maintenance, disconnect
the power supply.
•
Ensure that the grounding cable is properly
grounded and the pin is properly connected to
a grounded socket.
•
Always inspect carefully the grounding.
•
Before connecting the input, select an appropriate
grounding.
•
Inspect regularly the power if they are damage or
if they present lack of insulation. A damaged cable
must be replaced immediately. Cables must be
replaced if any damage is found. Improper repair of
the insulation may cause death or injury.
•
Turn the device off when it is not used.
•
Replace the cable if you notice any signs or abrasion
or local damage.
•
Do not coil the cable around your body.
•
The welded workpiece is to be properly grounded.
•
Use only equipment in good condition.
•
Any damaged elements of the device are to be
repaired or replaced.
•
During work at elevated heights, use safety harness.
•
All the elements of equipment and safety should be
located in one place.
•
It is forbidden to deactivate the safety system.
•
Use only pistols listed in the instruction manual.
•
When activating the release, keep the pistol tip and
the arc as far as possible from your body.
•
Attach the working cable to an appropriate metal
contact of the welded workpiece (not to an element
which may fall off) or to the work table as close to the
welder as seems appropriate.
•
The working clamp is to be insulated, unless it
is connected to the workpiece, in order to avoid
contact with metal.
After disconnecting the supply cable, the device may
still contain SIGNIFICANT VOLTAGE.
After turning the device off and disconnecting the power
cable, check the voltage on the input capacitor and ensure
the voltage value is zero, otherwise do not touch any
element of the device.
The capacitors are to be inspected in accordance with the
guidelines in the operation section of this manual.
ELECTRIC SHOCK may be lethal.
Unsecured elements of the rectifier may explode at the
moment of turning on the power supply. When using the
rectifier, always use a protective mask and working clothes
with long sleeves.
EXPLODING PARTS OF THE DEVICE may cause injury.
Metal splinters during welding constitute a health hazard.
SPLINTERS AND SPARKS MAY CAUSE INJURIES.
•
Always wear a protective mask with side shield.
•
Always wear appropriate protective clothes in order
to protect your body.
•
Always wear earplugs or other hearing protection
in order to prevent the splinters from entering your
ears.
•
During welding, the electric arc generates significant
amount of visible and invisible radiation (UV and IR
radiation) which may damage eyesight and skin
ELECTRIC ARC RADIATION may damage eyesight and
skin.
•
Always use face protection (helmet or shield) and eye
protection with glass with appropriate tint, acting as
filter and protecting the eyes during cutting.
•
Safety standards propose tint no. 9 (no. 8 at
minimum) for every current intensity below 300 A.
A lower shield tint may be used if the arc covers the
workpiece.
•
Always use permitted safety goggles with side shield
under the helmet or another protection.
•
Use workplace shields in order to protect other
people against blinding light or splinters. Warn
bystanders not to look at the electric arc.
•
Use protective clothes made of non-flammable
and non-conductive material (leather, thick wool or
cotton) and appropriate working footwear.
THERMAL PROTECTION
The thermal protection system is activated when the device
exceeds the activation time. It causes the device to switch
off. The status indicator on the front panel glows. The fan
works until the device is cooled. After cooling the device to
the operational temperature, it can be restarted.
DUTY CYCLE
The duty cycle is the percentage of the operating time
(measured in minutes) of a 10-minute period in which
the machine is used continuously in normal temperature
conditions. 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. Repeated situations of exceeding the duty
cycle values may lead to serious damage of the machine.

STARTING WITH THE OPERATION
A. UNPACKING
Unpack all the items which are in the box and make sure
that you have received all items which are listed on the
packing list.
B. WORK ENVIRONMENT
Make sure that the work area is well ventilated. The unit
is cooled by an axial fan that provides an air flow for the
electronics through the rear panel.
(Note! The housing must be installed in order to ensure
that the vent holes are closer to the front of the machine).
Leave at least 15 cm at the front and 15 cm at both sides for
cleaning. If the machine is operated without the adequate
cooling, the length of the duty cycle will be greatly reduced.
C. CABLE CONNECTIONS
Each unit is equipped with a main power cable, which is
responsible for providing current and voltage to the device.
If the device is connected to power, which exceeds the
required voltage, or if the wrong phase is set, it may lead
to severe damage to the unit. This is not covered by the
warranty for the equipment and the user will be responsible
for such situations.
D. TORCH CONNECTIONS
Connect the torch to the inverter by connecting the air
tube that is attached at the end of the torch to the torch
connector on the front part of the machine. Ensure that the
connection is secure by tightening it slightly with a spanner.
However you should not make it too tight.

and the machine will stop functioning. This
means that the machine is now being cooled
in order to be able to restore temperature
control again after the device has overheated.
Therefore the machine is stopped. During this
process, the red warning light on the front
panel lights up. In this case it is not necessary
to remove the power plug from the socket.
The ventilation system may be left on in order
to enhance the cooling of the machine. When
the red light goes dark, this means that the
temperature is now down to the normal level
and the unit can be put back into operation.
