TROUBLESHOOTING GUIDE
1. MACHINE DOES NOT WORK
Mains switch is ON, but relevant
operating status LED and digital
displays are not lit up
REMEDY CAUSE FAULT
Break in mains lead,
Mains plug is not plugged in Check mains lead, and mains voltage
if necessary
Mains power socket or plug is faulty Replace any faulty parts
Mains fuse is faulty Change the fuse
Torch control plug is not plugged in,
or the plug-in connection is faulty Plug in the control plug and secure it, check
connection, replace if necessary 2. NO REACTION WHEN TORCH
TRIGGER IS ACTUATED
Mains switch is ON, relevant operating
status LED and digital displays are lit up,
but LED displays
, ,
do not light up
when trigger is pulled back
Torch switch (micro-switch) or torch control
line is faulty
Repair or replace torch
The "Power ON" reset time after switch-on
(10 sec) has not yet elapsed
After switching on the mains switch, wait for
about 10 sec before starting to weld
3. NO WELDING CURRENT
Mains switch is ON, relevant operating
status LED and digital displays are lit up,
LED displays
, ,
light up
when the trigger is pulled back.
HF and shielding gas are present
Clamp the earth cable to the workpiece
Earth cable is not connected
Earth cable is plugged into wrong current
socket
Plug the earth cable into the socket and
secure it
Open up the machine and blast clean with dry
compressed air
4. NO WELDING CURRENT
Mains switch is ON,
relevant operating status LED is lit up,
digital displays
and
are showing
ErrO_t
Max. duty cycle has been exceeded or fan is
faulty Allow the machine to cool, do not switch off,
check working of fan
Primary module is very dirty
5. ARC SOMETIMES BREAKS
(in AC-TIG)
Tungsten electrode is underloaded
Use a suitable diameter of electrode for the
amperage in question
6. ARC SOMETIMES BREAKS
(in manual electrode)
Arc-drop voltage of electrode is too high Use an alternative electrode if possible
Cooling air-stream is insufficient Ensure adequate supply of cooling air
Short circuit in welding-current circuit in electrode
welding mode
(longer than 1 sec)
UTC control unit AC (DC) is faulty Change the UTC-AC (DC)
Eliminate the short circuit in the welding-current
circuit
Torch is faulty Change the torch
7. NO SHIELDING GAS
all other functions are OK
Gas hose is not connected, or is faulty
Pressure regulator is defective Change the regulator
Gas cylinder is empty Change the gas cylinder
Connect the gas hose, replace faulty hose
Call after-sales service
Gas solenoid valve is defective
Using internal program parameters, increase
the gas post-flow time
(depends on welding
amperage)
8. NO GAS POST-FLOW
Tungsten electrode discolours after
end of welding
Gas post-flow time is set too short
Increase gas pre-flow time Gas pre-flow time is set too short 9. POOR ARC IGNITION
Welding torch is faulty Replace the torch
UTC-AC (DC) control unit is defective
Change the UTC-AC (DC) control unit
HF is too weak See Pt. 10 below
DC: Tungsten electrode is alloyed up,
or pointed tip is damaged
Sharpen tip of tungsten electrode
Shorten the tungsten electrode and form a
new dome at the tip
Set correct needle diameter AC: Tungsten electrode is alloyed up,
or domed tip is damaged
Incorrect needle diameter
has been set
Tungsten electrode is underloaded Use a suitable electrode for the amperage
(also start-arc amperage) in question
Gas nozzle is dirty; HF jumps over the gas
nozzle onto the workpiece Use a new ceramic nozzle
Gas nozzle is too small for the diameter of
tungsten electrode used Use a bigger gas nozzle
Torch is damaged: torch body, protective
hose etc. are faulty Replace the damaged parts or change the
torch
See Pt. 7 above 10. HF IS TOO WEAK No shielding gas, or not enough
Warning! Machine may only be opened up by suitably qualified and skilled personnel!
