RECOMMENDATION TO REDUCE ELECTRO-MAGNETIC EMISSIONS
General
The user is responsible for installing and using the welding equipment according to manufacturer's instructions. If
electromagnetic disturbances are detected, then it shall be the responsibility of the user of the welding equipment to
sort the situation out with the technical assistance of the manufacturer.
Evaluation of the welding area
Before installing the unit, the user shall make an assessment of potential electromagnetic problems in the
surrounding area
a. Other wiring, control cables, telephones and communication cables; above, below and adjacent to the
welding machine
b. Radio and television transmitters and receivers;
c. Computer and other control equipment;
d. Equipment critical for safety purposes such as safety checks of industrial equipment;
e. The health of persons in the vincity, for example persons who wear pacemakers and hearing aids;
f. Equipment used for calibration or measurements;
g. The immunity of other equipment in which the equipment is to be used. The user must ensure that other
equipment used in the same placet is compatible. This may require additional protection measures;
h. The time of day when welding or other activities are carried out
i. The size of the area to be considered will depend on the structure of the building and any other
processes in the area. The surrounding area may extend beyond the boundaries of the buildings.
Recommendation to reduce electro-magnetic emission
Mains power supply: the equipment must be connected to the power mains as specified in the
a.
Manufacturer's instructions. If interference occurs, additional precautions such as filtering of the mains
supply may be required. The supply cable in the welding machine's permanent installations may have to
be screened in metal conduits or similar.The screening should be electrically continous for the entire
lengh of the cable. It should also beconnect to the welding machine with a good electrical contact
between the metal conduit and the casing.
Welding cables: The welding cables should be kept as short as possible and should be positioned close
b.
together, running at or close to the floor level.
Protection and reinforcement: Selective screening and shielding of other cables and equipment in the
c.
surrounding area may alleviate problems of interference. Screening of the entire welding area may be
considered for special applications
d. Connect the earth directly to the metal piece to be welded: Where necessary, the connection of
the workpiece to earth should be made by a direct connection to the workpiece, but in some countries
where direct connection is not permitted, the bonding should be achieved by suitable capacitance,
selected according to national regulations.

TROUBLESHOOTING

Anomalies
The device does not deliver any current and the
yellow thermal indicator  lights up.
The display is on but the device does not deliver
any current.
The unit is on and you feel tingling sensation while
touching the unit's case.
The display is on but the device does not deliver
any current.
When starting up, the display indicates
Unstable arc
The tungsten electrode gets oxidised and tern at
the end of welding.
The electrode melts
Causes
Thermal protection is active
The earth clamp or electrode holder is
not properly connected to the unit.
The welding unit is not correctly
connected to the earth.
The earth clamp or electrode holder is
not properly connected to the unit.
The voltage is not within the range 230V
.
+/- 15%
Failure of the tungsten electrode
Gas flow rate set too high
Welding zone
Default coming from post-gas or the gas
has been stopped prematurely.
Polarity error
Remedies
Wait for the end of the cooling period, around 2
minutes. The indicator light  turns off.
Check the connections.
Check the plug and the earth of your electrical
network.
Check the connections.
Have the electrical installation checked.
Ensure the correct size of electrode is being used
Ensure the tungsten electrode is correctly prepared
Reduce gas flow rate
Protect welding zone against air flow
Check and tighten all gas connections. Wait until
the electrode cools down before stopping the gas.
Check that the earth clamp is connected to the +
pole
