Troubleshooting - WilTec TIG180 Operation Manual

TROUBLESHOOTING

1. Maintenance or repairs performed by technical assistance centers not authorized by the manufac-
turer will immediately render null and void the manufacturer warranty.
2. If user want to operate machine as following, the operator must specialist in field of electrify and
safety.
3. If you have any questions about the suggested solutions or are unable to complete them, please
contact the manufacturer or an authorized service partner immediately.
TIG180, TIG200
Faults
1.Power indicator is
not lit, fan does not
work/no welding out-
put
2.Power indicator is
lit, fan does not work
or revolve several cir-
cles/no welding output
3. Fan is working,
indicator is not lit and
sound of HF arc-strik-
ing cannot be heard/
wiping welding cannot
strike arc.
4. Abnormal indicator
is not on, sound of HF
arc-striking can be
heard, but there is no
welding output.
5. Abnormal indicator
is not lit, sound of HF
arc-striking cannot be
heard, wiping welding
can strike arc.

1. Power switch is out of work.
2. Check if electrify wire net (which is connected to input cable) is in
work.
3. Check if input cable is out of circuit.
1. Maybe you connected wrong to 380v power so that the machine is
in protection circuit. Connect to 220v power and operate machine
again.
2. 220v power is not stable (input cable is too slender) or input cable is
connected to electrify wire net which causes that the machine is in
protection circuit. Add the section of cable and tighten input connec-
tor firmly. Close machine 2-3 minutes then switch it on again.
3. Cable is loose from switch to power panel; tighten them again.
4. Switch the machine on and off several times because it is in protec-
tion circuit. Shut down the machine 2-3 minutes and then switch it
on again.
5. Main circuit 24v relay of the power panel is not closed or has dam-
aged. Check 24v power source and relay. If relay has been dam-
aged replace it with same model.
1. Positive and negative electrodes of VH-07 insert component voltage
should be about DC308v from power panel to MOS board.
(1) If circuit is broken and silicon bridge has poor contact.
(2) If some of four high electrolytic (about 470UF/450V) of power
panel capacitor are leaking.
2. There is a green indicator in auxiliary power of MOS board ,if it is not
on, auxiliary power is out of work .Check fault spot and connect with
seller.
3. Check if connectors have poor contact.
4. Check control circuit and find out reasons or connect with seller.
5. Check if control cable of torch is broken.
1. Check if torch cable is broken.
2. Check if grounding cable is broken or not connected to welding
piece.
3. Output terminal of positive electrode or torch electrify is loosened
from inter-machine.
Primary cable of arc-striking transformer is not connected to power

panel firmly; tighten it again.
Arc-striking tip is oxidized or too far away; give a good polish to it or

change if there is about 1 mm between arc-striking tip.
Switch (sticking/argon-arc welding) is damaged, replace it.

Some of HF arc-striking circuit components are damaged; find out

and replace them.
