7/27
Fire risks :
Suppress all flammable products from the working area. Do not works near flammable gas.
Smokes :
Do not inhale gas or welding smokes. If indoors ventilate the area well and/or use local
extraction ventilation equipment to remove fumes and gases.
Extraprecautions :
Any welding operation :
- in environments with increased risk of electric shock,
- in confined spaces,
- in the presence of flammable or explosive materials
must be evaluated in advance by an “Expert supervisor” and must always be carried out in
the presence of other people trained to intervene in case of emergency.
Technical protection measures MUST BE taken as described in the TECHNICAL
SPECIFICATION "IEC 62081".
Welding in raised positions is forbidden unless safety platforms are used.
The persons carrying pacemaker have to consult a doctor before using these machines
Do not use the unit to thaw tubing.
In TIG welding, manipulate the gas bottle carefully. Indeed, there are risks if the bottle or the bottle
valve are damaged.
TROUBLESHOOTING
Anomalies
Causes
Remedies
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
the earth.
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
during one second and turns off.
The voltage is not
included in the range
230V +/- 15%
Have the electrical installation
checked.
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 flow
rate
Reduce gas flow rate
The tungsten electrode gets oxidised and
tern at the end of welding.
Welding zone
Protect welding zone against air
flows
Default coming from
post-gas or the gas has
been stopped
prematurely.
Increase post-gas duration
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 +
