SYMPTOM. ANOMALY
PROBABLE CAUSE.
POSSIBLE SOLUTION.
GENERAL PROBLEM.
NOTHING WORKS.
Machine lacks tension in some or all of its vital
elements.
1. Note that the voltage at the input of the machine exists;
otherwise it is necessary to change the socket. It is convenient
to observe if there are any magnetothermal "jumped ".
2. Check the power source fuses located in the center panel.
(See spare parts sheet)
3. The machine panels must be dismantled by testing the log-
ical points of the electrical scheme for this case.
ELECTRIC LIMITER JUMP.
Caliber of magnetothermal low for this case.
There may be a short circuit that causes the limit
switch to trip.
Replace the magnetothermal with a larger one. It is important
that the circuit breaker has a characteristic curve, slow type .
In the event that the electrical installation is of limited power,
it must prove that the welding work is carried out at lower
current levels.
EQUIPMENT MAKES "NOISE"
Loose metal housing.
Check and tighten the housing.
Defective electrical connections.
Tighten connections correctly.
Damaged or poorly secured fan.
Check Fan.
GREEN INDICATOR LD1 ON,
EQUIPMENT DOESN'T
WORKS
Active protection system. Amber pilot "LD2" ON.
Equipment overheated, wait for cooling.
Supply voltage outside nominal range. Switch power supply.
WELDING ELECTRODE BURNS
TIG
Excessive welding intensity for a specific elec-
trode.
Reduce the welding current or replace the electrode with a
larger diameter.
Using reverse polarity.
Place the electrode to the negative pole.
Electrode Type
Change type of electrode
Lack protective gas.
Adjust at an adequate flow rate.
THERE IS AN ABNORMAL
HEATING ON THE
EQUIPMENT. THERMAL
PROTECTION WORKS
QUICKLY.
The equipment is located in such a way as pre-
venting proper ventilation.
Place the equipment in an area where there is air renewal.
Fan does not works.
Replace fan.
The equipment is located in a warm atmos-
phere.
Avoid a location with direct sun exposure.
An internally connection loose.
Check electrical power connections.
MACHINE CONNECTED AND
LD1 IS ON, WHEN PRESS
THERE IS NOT REACTION
Gun switch failure that does not make contact
correctly.
Change gun microswitch.
NO PRESS BUT GAS STILL
FLOWS.
There is one impurity inner the chamber of the
solenoid valve that prevents the piston closing
completely.
Disassemble and clean solenoid valve.
The configured post-flow value is high.
In configuration menu correct the value of post-flow time
FAULT DESCRIPTION
THE
Overheating in power source. The thermal protection has switched off the equipment.
OVT
Detecting that there is no welding voltage.
OVC
Over current..
CON
Lack of communication between the electronic front plaque and the control plaque.
CON
Communication fault CENTER (CEN) or control peripheral (CON)
GND
Ground fault
OVV
Input power overvoltage (U1> 470 V)
UNV
Input power undervoltage (U1 <330 V)
NPH
Power Line Phase Fault
REF
Lack of coolant pressure..
ONLY SPECIALIZED PERSONAL CAN MAKE REPAIR AND MAINTENANCE OPERATIONS.
STARTING AS ENDING OF A REPAIR, CHECK THE EQUIPMENT INSULATION LEVELS. DISCONNECT
ELECTRONIC PLATES WHEN MEASURING INSULATION.
The insulation meter shall be of a voltage of 500 V D.C and shall be applied at the following points in circuit:
- Power - Ground: Ra> 50 Mohms.
- Welding - Ground: Ra> 50 Mohms.
- Power - Welding: Ra> 50 Mohms.
BEFORE TURNING ON EQUIPMENT CHECK IT IS IN EMPTY.
DO NOT OPERATE THE ON / OFF SWITCH WITH ELECTRICAL CHARGING COUPLED TO THE WELDING
CONNECTORS.
