Basic rules during welding by TIG method:
1. Purity - grease, oil and other impurities must be
removed from the weld during welding. It is also
necessary to mind purity of additional material and
clean gloves of the welder during welding.
2. Leading additional material - oxidation must be
prevented. To do so, flashing end of additional ma-
terial must be always under the protection of gas
flowing from the hose.
3. Type and diameter of tungsten electrodes - it is
necessary to choose them according to the values
of the current, polarity, type of basic material and
composition of protective gas.
4. Sharpening of tungsten electrodes - sharpening the
tip of the electrode should be done in trav-erse/
horizontal direction. The tinier the roughness of
the surface of the tip is, the calmer the burning of
the el. arc is as well as the greater durability of the
electrode is.
5. The amount of protective gas - it has to be adjust-
ed according to the type of welding or according to
the size of gas hose. After finishing the welding gas
must flow sufficiently long to protect material and
tungsten electrode against oxidation.
Typical TIG welding errors and their impact on weld
quality:
The welding current is too -
Low: unstable welding arc
High: Tungsten electrode tip breaks lead to turbulent
arcing.
Further, mistakes may be caused by poor welding torch
guidance and poor addition of additive material.
Warning about possible problems and their
remedy
The extension cord and welding cables are considered
the most common cause of the problem. If you have
any problems, follow these steps:
• Check the value of the supplied mains voltage.
• Make sure that the power cord is fully connected to
the power outlet and the main power switch.
• Make sure the fuses or the circuit breakers are OK.
If you are using the extension cable, check its length,
cross-section and connection.
Make sure the following parts are not defective:
• Main switch of the grid
• Power socket and main power switch
NOTE: Despite your required technical skills necessary
to repair the generator, we recommend contacting
trained personnel and our Technical Service Department
in case of damage.

Error messages

Error message ERR
The machine thermal protection (machine overheating)
has been activated. The machine will not respond to
any buttons and will not operate until the machine has
cooled down.
Signaling - - -
Short-circuit signaling on output terminals. E.g. sticking
electrode, faulty output voltage.
ROUTINE MAINTENANCE AND INSPECTION
Check according to EN 60974-4. Always before Use the
machine to check the condition of the welding and
supply lines cable. Do not use damaged cables.
Perform a visual check:
• welding cables
• power grid
• welding circuit
• covers
• control and indicator elements
• general status
WARNING
When operating the machine on higher welding
currents, the taking of the machine from the network
can exceed the value 16 A. In this case, the fork must be
replaced and the industrial fork corresponding to the
20 A fuse! This protection must also correspond to the
design and protection of the electrical wiring.
