•
Chemical substances (lubricants, solvents) must be removed from the surfaces of welded objects as
they burn and emit toxic smokes under the influence of temperature.
•
The welding of galvanised objects is permitted only when efficient ventilation is provided with filtration
and access to fresh air. Zinc fumes are very toxic, an intoxication symptom is the so called zinc fever.

3. OPERATION
3.1 GENERAL NOTES
•
The device must be applied according to its purpose, with observance of OHS regulations and
restrictions resulting from data included in the rating plate (IP level, operation cycle, supply voltage,
etc.).
•
The machine must not be opened as it will cause warranty loss and, in addition, exploding, unshielded
elements can cause serious injuries.
•
The producer does not bear any responsibility for technical changes in the device or material losses
caused by the introduction of the said changes.
•
In case of incorrect device operation, contact the service centre.
•
Louvers must not be shielded – the welder must be positioned at 30 cm distance from objects
surrounding it.
•
The welder must not be kept under your arm or near to your body.
•
The machine must not be installed in rooms with aggressive environments, high dustiness and near
devices with high electromagnetic field emission.
3.2 DEVICE STORAGE
•
The machine must be protected against water and moisture.
•
The welder must not be positioned on heated surfaces.
•
The device must be stored in a dry and clean room.
3.3 CONNECTING THE DEVICE
3.3.1 Connecting the power
•
Connection of the device 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 conduits to the machine must be avoided.
•
One-phase welders should be connected to the socket fitted with an earthing prong.
•
Welders powered from a 3-Phase network are delivered without a plug, the plug must be obtained
independently and installation should be assigned to a qualified person.
PLEASE NOTE: THE DEVICE MAY ONLY BE USED UPON CONNECTION TO AN
INSTALLMENT WITH A PROPERLY FUNCTIONING FUSE!

2.
ERROR INDICATOR = The indicator lights in the following two situations:
a) If the machine has malfunctioned and cannot be operated.
b) If the cutting device has exceeded the standard working time, the protection mode is initiated
and the machine will stop functioning. This means that the machine is now being cooled in order
to be able to restore the 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 unplug the device. 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 set to the normal level and the unit can be put back into operation.

5. CABLE CONNECTIONS
INSTRUCTIONS FOR CABLE CONNECTIONS:
1.
Connect the mass cable to the socket marked with „+".
2.
Then connect the cable with MMA electrode holder to socket marked with the „-" sign.
WARNING! The polarization of the cables can be different! All polarisation information should be
shown on the packaging supplied by the electrode manufacturer.
3.
Now you can connect the power cord and turn the power on, once the mass cable is connected to the
workpiece, you can start working.
6. DISPOSING OF PACKAGING
The various items used for packaging (cardboard, plastic straps, polyurethane 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!
