MMA-TIG
The device does not deliver any
current and the yellow indicator
lamp of thermal defect (6) lights
up.
The welder thermal protection has
turned on.
Wait for the end of the cooling
time, around 2 minutes. The indi-
cator lamp (6) turns off.
The display is on but the device
does not deliver any current.
The cable of the earth clamp or
electrode holder is not connected
to the welder.
Check the connections.
If, when the unit is on and you put
your hand on the welding unit’s
body, you feel tingling sensation.
The welding unit is not correctly
connected to the earth.
Check the plug and the earth of
your electrical network.
The display is on but the device
does not deliver any current.
The cable of the earth clamp or
electrode holder is not connected
to the welder.
Check the connections.
When starting up,
the display indicates .
The voltage is not included in the
range 230V +/- 15%
Have the electrical installation
checked.
TIG
Instable arc
Default coming from the tungsten
electrode
Use a tungsten electrode with the
adequate size
Use a well prepared tungsten
electrode
Too important gas ow rate Reduce gas ow rate
The tungsten electrode gets
oxidised and tern at the end of
welding.
Welding zone
Protect welding zone against air
ows
Default coming from post-gas or
the gas has been stopped prema-
turely.
Check and tighten all gas connec-
tions. Wait until the electrode cools
down before stopping the gas.
