5. ANOMALIES. PROBABLE CAUSES. POSSIBLE SOLUTIONS.
SYMPTOM. ANOMALY. PROBABLE CAUSE. POSSIBLE SOLUTION.
GENERAL PROBLEM.
NOTHING WORKS.
The machine has no voltage in one or all its vital
elements.
1. Make sure there is voltage at the entry to the machine; if
not the intake must be changed. It is advisable to see if any
magnetothermal has "blown".
2. The machine panels must be removed testing the logical
points of the electrical diagram.
LIMITER TRIPS.
Magnetothermal switch has low gauge for the
case.
There may be an overload, which is what
causes the limiter to trip.
Change the magnetothermal for another larger gauge
one. It is important for the magnetothermal switch to have a
characteristic slow type curve. In the event that the electrical
installation has limited power, the welding work must be
tested at lower current levels.
IT CAUSES NOISE
Loose metal casing. Review and screw casing.
Defective electrical connections. Correctly tighten the connections.
Damaged or poorly attached fan. Examine the fan.
IF THE GREEN INDICATOR
LD1 IS ON THE APPLIANCE
DOES NOT WELD
Active protection system. Amber light “LD2” on.
Equipment overheated, wait until the equipment cools down.
THE ELECTRODE BURNS IN
TIG WELDING
Excessive welding intensity for a certain
electrode.
Decrease welding current or change electrode for one with
larger diameter.
Use of reverse polarity. Place electrode to negative pole.
Type of electrode Change the electrode type.
Lack of protection gas. Adjust at an appropriate flow.
THE EQUIPMENT HEATS UP
ABNORMALLY.
THE THERMAL PROTECTION
ACTIVATES QUICKLY.
The equipment is positioned in such a way that
proper ventilation is prevented.
Place the equipment in an area where the air is constantly
replaced.
The fan does not work. Replace the fan.
The equipment is located in a very hot
environment.
Avoid positioning where there is direct exposure to the sun.
There is a loose connection inside the
equipment.
Review the power electrical connections.
ALTHOUGH THE MACHINE IS
CONNECTED AND WITH THE
SWITCH LD1 ON, THERE IS
NO REACTION WHEN
PRESSED
Failure of the welding torch switch which does
not make perfect contact.
Change the torch microswitch.
WHEN THE SHIELDING GAS
IS RELEASED IT CONTINUES
FLOWING.
There is impurity in the inside chamber of the
solenoid valve which prevents the piston from
closing completely.
Dismantle and clean the electrovalve.
The configurated value of post-flow is very high. Change in the settings menu the post-flow time value TPS.
WHEN FINISHING WELDING
THE WIRE REMAINS STUCK
TO THE TORCH CONTACT
TUBE.
The configurated value of burn-back is very
high.
Change in the settings menu the value of the burn-back
time correction (see section 3.6.2).
WHEN FINISHING WELDING
THE FINAL WIRE LENGTH IS
VERY GREAT.
The configurated value of burn-back is too low. Change in the settings menu the value of the burn-back time
correction (see section 3.6.2).
The torch is withdrawn immediately when torch
push-button is no longer pressed.
The final wire length control system requires the welding
torch not to be immediately withdrawn when the torch push-
button is no longer pressed.
THE EQUIPMENT DOES NOT
WELD CORRECTLY IN
MIG/MAG MODE.
"IT ADJUSTS BADLY"
Low effective welding voltage. Output wave
does not correct.
Check that there is not a phase failure in the supply power.
Check that the electrical contact elements of the welding
circuit are correct: Welding earth and surfaces are rusty or
very dirty. Contact nozzle with greater diameter than the
wire, etc.
Test the electrical diagram of the power source.
Input and output voltages to the rectifier.
The diameter of used wire does not match to
selected program.
Verify the use of the appropriate diameter and replace the
erroneous one.
The welding wire has a mechanical resistance
at the outlet, which prevents it from having a
regular speed.
Examine the welding gun. Blow the inside (cable) with
compressed air.
Selection of wrong synergic program.
Verify the program selection criteria : filler materials, gas
mixture y and wire diameter.
Consumable badly fit or in bad condition. Review the consumable adjustment and replace if faulty.
Unsuitable pressure of tightening knob in
driving operation.
Adjust the pressure until the problem disappears.
