Troubleshooting Causes Solutions
MMA-TIG
The machine does not deliver any
current and the yellow thermal
protection indicator is switched on
(6).
The thermal protection has swit-
ched on.
Wait the end of the cooling cycle,
about 2 min. The indicator (6)
switches o.
MMA-TIG
The earth clamp, the electrode
holder or the welding torch are not
connected to the unit.
Check the connections
The product is connected to the
mains, you are feeling tingling
when touching the case.
The earth contact is faulty.
Check the plug and the earth of
your installation.
The machine welds poorly. Polarity error
Check the recommended polarity
(+/-) on the electrode box.
When the machine starts, the
display shows .
The power supply voltage is not
suitable (230 V +/- 15%)
Check the power supply network
or the generator
TIG
Unstable arc
Fault due to the tungsten electrode
Use an electrode size more sui-
table to the thickness of your
metal.
Use an tungsten electrode properly
prepared.
Gas ow too high Reduce the gas ow
The tungsten electrode becomes
oxidized and tainted at the end of
the welding
Welding area.
Protect the welding area against
draught.
Gas problem, or gas ow stops too
early
Check and tighten every gas
connection. Wait for the electrode
to cool down before switching o
the glas ow.
