The device does not deliver any
current and the yellow indicator lamp
of thermal defect
lights up.
The welder thermal
protection has turned
on.
Wait for the end of the cooling
time, around 2 minutes. The
indicator lamp
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

Check the plug and the earth of
your electrical network.
Your unit does not weld correctly.
Polarity error.
Check the polarity advised on
the electrode packaging.
When starting up, the display indicates
or during one second and
turns off.
The voltage is not
included in the range
230V +/- 15% for IMS
1305, 1400, 1700,
1905; 400V +/- 15%
for IMS 2510
Have the electrical installation
checked.
Use a tungsten electrode with
the adequate size
Default coming from
the tungsten electrode
Use a well prepared tungsten
electrode
Instable arc
Too important gas flow
rate
Reduce gas flow rate
Welding zone
Protect welding zone against air
flows
Increase post-gas duration
The tungsten electrode gets oxidised
and tern at the end of welding.
Default coming from
post-gas or the gas has
been
stopped
prematurely.
Check and tighten all gas
connections. Wait until the
electrode cools down before
stopping the gas.
The electrode melts
Polarity error
Check that the earth clamp is
really connected to +
