The MMA mode is selected instead of the TIG mode.
The pedal/torch remote control is not properly connected. Check the connection of remote controls.
There is a defect in the welding circuit connection.
No shielding gas.
The electrode is contaminated.
The earth connection and torch polarity are reversed.
The workpiece is dirty.
Excessive air flow.
Reversed earth and torch connections.
Tungsten electrode has been contaminated.
Wrong shielding gas.
The tip of the torch is defective or is not correct.
The towline material and/or diameter are not suitable for
the material in use (or it is in poor condition).
Wrong rollers for the material in use.
Tensor pressure incorrect or rollers worn.
Incorrect brake adjustment.
The automatic or synergistic adjustment speed is not suita-
ble for the needs of your application.

In TIG mode, the arc does not start.
CAUSE
Excessive consumption of the tungsten electrode in TIG mode
CAUSE
In MIG mode, supply wire speed is inadequate
CAUSE
Make sure that the TIG mode is activated.
Check torch and earth clamp are properly connected
to their respective power outlets. Check the state of
the cables and their connections.
Connect shielding gas. Make sure to use the proper
shielding gas.
Clean the tungsten electrode. A contaminated elec-
trode can affect the ignition sequence.
Check that the torch is connected to the right connec-
tor (-) and earth clamp to the left (+).
Remove dirt or paint chips.
An excessive air flow can move the shielding gas and
affect the arc.
Interchange the connection.
Clean the electrode.
Ensure sufficient flow level. Ensure you use inert
shielding gases for TIG welding processes.
Check that the tip matches the diameter of the wire in
use and check that the tip is free of dirt and projec-
tions.
Check towline type you use. If it is in poor condition,
replace it.
Check that the rollers are suitable for the material in
use and that they are in good condition. Follow the
instructions in this manual for adjusting the pressure
of the rollers.
Check the adjustment of the brake in the coil holder.
Select the manual mode to set the desired ratio bet-
ween wire speed and welding voltage.
