FAULT
1. MACHINE DOES NOT WORK
Mains switch is ON,
but relevant operating status
LED - and digital displays
and are not lit up
2. NO REACTION WHEN TORCH
TRIGGER IS ACTUATED
Mains switch is ON,
relevant operating status
LED - and digital displays
and are lit up, but LED displays
, , do not light up when trigger is
pulled back
3. NO WELDING CURRENT
Mains switch is ON,
relevant operating status
LED - and digital displays
and are lit up, LED displays
, , light up when the trigger is
pulled back.
HF and shielding gas are present
4. NO WELDING CURRENT
Mains switch is ON,
relevant operating status
LED - is lit up,
digital displays and
t - P e.g. 82.2 (overtemp. primary) or
t - S e.g. 81.2 (overtemp. secondary)
5. NO WELDING CURRENT
Mains switch is ON,
relevant operating status
LED - is lit up,
digital displays and
Err 09 (secondary overvoltage fault)
6. ARC SOMETIMES BREAKS
(in AC-TIG)
Mains switch is ON,
relevant operating status
LED - and
digital displays and
7. ARC SOMETIMES BREAKS
(in manual electrode)
Mains switch is ON,
relevant operating status
LED - and
digital displays and
8. NO SHILDING GAS
all other functions are OK
CAUSE
Break in mains lead,
Mains plug is not plugged in
Mains fuse is faulty
Mains power socket or plug on machine is
faulty
Torch control plug is not plugged in, or the
plug-in connection is faulty
Torch switch (micro-switch) or torch con-
trol line is faulty
The "Power ON" reset time after switch-on
(10 sec) has not yet elapsed
Earth cable is not connected
Earth cable is plugged into wrong current
socket
Torch is faulty
TC 1 MC control unit AC (DC) is faulty
Short circuit in welding-current circuit in
electrode welding mode (longer than 1 sec)
Max. duty cycle has been exceeded or fan
is faulty (alternate display of primary and
secondary temperature, i.e. t - P / t - S)
Cooling air-stream is insufficient
are showing
Primary module is very dirty
Overvoltage at the welding sockets
are showing:
Tungsten electrode is underloaded
are lit up
Arc-drop voltage of electrode is too high
are lit up
Gas cylinder is empty
Pressure regulator is defective
Gas hose is either not connected, or is
faulty
Welding torch is faulty
TC 1 MC AC (DC) control unit is defective
Gas solenoid valve is defective
REMEDY
Check mains lead, and mains voltage if
necessary
Change the fuse
Replace any faulty parts
Plug in the control plug and secure it,
check connection, replace if necessary
Repair or replace torch
After switching on at the mains switch,
wait for about 10 sec before starting to
weld
Clamp the earth cable to the workpiece
Plug the earth cable into the
and secure it
Change the torch
Change the TC 1 MC AC (DC)
Eliminate the short circuit in the welding-
current circuit
Allow the machine to cool
é do not switch off, check working of fan
Ensure adequate supply of cooling air
Open up the machine and blast clean with
dry compressed air
(see "Care and maintenance" on p. 21)
Switch machine off and then on again. If
the fault happens again, call after-sales
service
Use a suitable diameter of electrode for
the amperage in question
Use an alternative electrode if possible
Change the gas cylinder
Change the regulator
Connect the gas hose, replace faulty hose
Replace the torch
Change the TC 1 MC AC (DC) control unit
Call after-sales service
