1) Preliminary analyse and advice on the GYSMI TIG 160HF
1.1) Reminder about safety
¾
The interventions made on the welding machine must be entrusted to qualified people.
¾
The welding machine must be disconnected and you will have to wait at least 30 minutes to intervene
with the welding machine, or discharge high voltage capacitor
1.2) The general advice on the intervention (internet page )
¾
Read the general information on Inverters Gysmi
¾
Before all interventions on the GYSMI TIG160 HF, check with the customer if it handles with a
“diagnostic of external breakdown “
on the model Inverter Gys
, (See Internet Page). and chapter 1.4 for
the breakdowns specific to Gysmi TIG 160 HF
¾
Read the clause of un-warranty on all the Inverter models
, (See Internet page)
.
¾
Carry out a visual monitoring to detect the obvious breakdowns (Zones of overheating, badly crimped
thimble, browned diode, burnt transformer, mechanical breakage, modulate power (destroyed component,
browned zone).
¾
Refer to the categories of not-reparable breakdowns on the Internet page.
1.3) The useful advice for the continuation of the diagnosis of the breakdowns.
¾
Don’t charge the welding machine immediately.
¾
Components CMS can be put in short-circuit or open circuit. The checking of resistors is done in
“ohmmeter”, the Zener diode and other diodes are measured in position “Diode” on the MultiMate. For all
connections on the chart, weld legs onto the indicated points of contacts (the card is varnished, attention
with the risks of bad contacts due to the dielectric isolation that occurred with varnish, use test probes with
a pointed end in order to break the layer of varnish).
¾
Provide a resistor( 1KΩ 7 W ) to discharge the capacitors of high capacity.
¾
Check the chapter of usual breakdowns on the present procedure.
-
Control point by point this file and carry out repairs if necessary
¾
See the
list of components SAV and their distributor’s reference
(see Internet page)

1.4) List of external breakdowns specific at Gysmi TIG 160 HF of external causes.
Failures
Origin
Solution
Orange Del on the back
face not lit
- No mains supply plug 230V
- Check the electric installation and the mains plug
voltage
Orange Del on the back
face is lit and orange
warning light is lit
- The thermal protection is engaged, the fan is
turning
- Wait for a cooling of the welding, the Fan is starting,
Wait for restarting the welding ( about 2 minutes )
- Power Group Protection The fan is turning
- Check the output voltage of the power group lower to
265V
- Make sure there is enough air
- Cooling time more than two minutes
Insufficient air for cooling
- Clean the filter
- Failure of the circuit SMI, the orange
warning is lighted continually
- Wait for a cooling of the welding, the fan is starting ,
wait for restarting the welding ( about 2 minutes )
If orange del is still lit ( check the welding machine).
MMA: no welding
- Selection switch
- Check middle position MMA.
- Connections of welding cables are incorrect
- Check the connections of the connections
- Putting incorrect earth
- Set the earth cable on the work piece
MMA: welding current
too weak
- The potentiometer “I” current is adjusted too
low
- Increase the current adjustment in order to equal the
electrode size.
TIG : HF absent
- Selection switch
- Check switch position on TIG (HF)
- Switch on the torch
- Check the connections of the torch
- Connections of welding cables incorrect
- Check the cable’s connections
- Electrode of the torch Polluted or damaged
- Clean your tungsten electrode and bevelled
- No more gas or end of the bottle of gas
- Check the pressure of the bottle
- HF generator
- Check the HF element in the welder
TIG: no Gas
- Gas bottle is imperfect
- Check the pressure of the bottle of gas
- Adjustment gas output of the bottle between 4 and 8
Litre / Min.
- Electromagnetic sluice value is imperfect
- Hear if electromagnetic sluice value commutate
without gas
- Connections of gas circuit are blocked
- Check the connections of the bottle
- Auxiliary power supply
- Check the welder
TIG: Oxidation of the
electrode and not remain
bright after the welding
- Insufficient gas
- Check the pressure of the gas bottle and the diffusion
of gas
- The gas stops before the end of the welding
process
- Increase the time of “post gas”
TIG: Electrode is melting
- Bad polarity of the electrode
- Connect the TIG welding torch to negative connector
- Bad protector Gas, Not protector Gas
- Use a protector Gas « Argon »

2) Diagnoses of the most usual breakdowns on the GYSMI TIG 160 HF
- Disconnect the welding Gysmi from the mains supply
- Unscrew the 12 screws of welding machine on the higher
cap
- Put the upper side card of PCB on the table.
- Reassembly in opposite order.
- Discharge the capacitors of high capacity with a resistor
1KΩ 7W ( to see photo opposite) between the points –HT
and +HT, and check the voltage with a MultiMate =0V.
Discharged Points
2.1) the welding machine does not start:
2.1.a) Control the resistor of charge R00_13
If the welding machine start under mains supply (lit green indicator, the fan turns), but the voltage of the capacitors
high Voltages is not present. The relay of load RL00_1 topple but the Relays RL00_2 and RL00_3 no topple.
Check with a MultiMate in position ‘‘ohmmeter’’ on the
pin’s R00_13 Value= 4.7Ω ref: 63146
R00_13
If the resistor is faulty, change the resistor.
Value 4.7Ω 11W Ref: 63146
RL00_1
RL00_2
RL00_3
2.1.b) Control of SMI power module
Check with a MultiMate in position ‘‘ohmmeter’’ on the
pin’s R07_1 Value= 10Ω
SMI Connector
If this one is in open circuit,
Check the SMI Module in visual.
R07_1
The power circuits are probably destroyed
Return the welding machine in SAV GYS

2.2) The welding machine trip the main supply
2.2.a
) Control of SMI insulation between of earth :
In the case of the welding trip the main supply:
Check with a MultiMate in position ‘‘Ohmmeter’’
Earth
Check between each primary screw and the earth.
You read a infinite resistor, in the contrary case the SMI is
probably put in short-circuit, to return the welding machine
to the SAV
Primary
2.3) the gas
leaking on the torch
:
You have a Gas leakage all the time of welding machine,
because the
Electromagnetic sluice is blocked
.
You try out in electromagnetic sluice gate into blowing to
3 or 4 bars by the front of the station and start the welding
machine for activate electromagnetic sluice.
Control the filter in the extremity of electromagnetic slice.
If you have a same problem, replaced electromagnetic
slice.
