PROBABLE CAUSE.
The machine has no voltage in one or all its
vital elements.
Magnetothermal switch has low gauge for the
case. There may be a short circuit, which is
what causes the limiter to trip.
Loose metal casing.
Defective electrical connections.
Damaged or poorly attached fan.
Active protection system. Amber light "LD2"
on.
Excessive welding intensity for
electrode.
Use of reverse polarity.
Lack of protection gas.
The equipment is positioned so that it prevents
correct ventilation.
The fan does not work.
The equipment is located in a very hot
environment.
There is a loose connection inside the
equipment.
Failure of the pistol switch which does not
make perfect contact.
Electrical failure o solenoid vale faulty.
There is impurity in the inside chamber of the
solenoid valve which prevents the piston from
closing completely.
Welding with the nozzle very close to the part
to be welded.
The torch is withdrawn immediately when torch
pushbutton is no longer pressed.
Low effective welding voltage. Output wave not
correct.
The welding wire has a mechanical resistance
at the outlet, which prevents it from having a
regular speed.
Unsuitable shielding gas.
POSSIBLE SOLUTION.
1. Make sure there is voltage at the entry to the machine, if
not the tapping must be changed. It is advisable to see if any
magnetothermal has "blown".
2. Check the power source fuses situated on the central
panel. (See Spare parts Sheet)
3. The machine panels must be removed testing the logical
points of the electrical diagram.
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.
Review and screw casing.
Correctly tighten the connections.
Examine the fan.
Equipment overheated, wait until the equipment cools down.
Supply voltage outside rated margin. Change supply tap.
a certain Decrease welding current or change electrode for one with
larger diameter.
Place electrode to negative pole.
Regulate at an appropriate flow.
Place the equipment in an area where the air is constantly
replaced.
Replace the fan.
Avoid positioning where there is direct exposure to the sun.
Review the power electrical connections.
Change the gun microswitch.
It must be established whether the fault comes from the
electronic board or if it is an electrical connection fault.
Check that solenoid valve coils are not open.
Dismantle and clean the electrovalve.
Correct the distance to the welding piece
The final wire length control system requires the welding
torch not to be immediately withdrawn when the torch
pushbutton is no longer pressed.
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 mass, rusty or very dirty surfaces,
contact nozzle with greater diameter than the wire, etc.
Test the electrical diagram of the power source. Input and
output voltages to the rectifier.
Examine the welding gun. Blow the inside (cable) with
compressed air.
When welding normal steels we advise the use of a gas
mixture Ar-CO2.
