TROUBLESHOOTING
This device integrates a default management system.
A series of messages displayed on the control board allows for a fault and anomalies diagnosis.
ABNORMALITIES
The machine does not deliver any current
and the yellow pictogram signalling thermal
protection is on.
The indicator is on but the product does not
deliver any current.
Voltage error
Despite the filling the tank, the error message
is still on.
Unstable arc
The tungsten becomes oxidised and dull at the
end of the welding
The tungsten electrode melts
Water level fault
Despite the filling the tank, the error message
is still on.
Flow fault
Cooling unit fault

SOLUTIONS
Wait the end of the cooling cycle of about 5
min. The pictogram disappears.
Check the connections
An power surge is at the origin of this mes-
sage.
Check the fuse.
Use an electrode size which is more suitable to
the thickness of your metal / workpiece.
Use a tungsten electrode which is properly
handled / prepared.
Reduce the gas flow
Protect the welding area agaisnt draught.
Increase the post gas duration
Check and tighten every gas connection.
Check the flowmeter with an no load ignition.
Check that the earth is connected to the +
Fill up the tank to the indicated MAX level.
Check the fuse.
Switch off the product and check the electrical
connection of the cooling unit.
