SYMPTOM. ANOMALY.
THERE ARE MANY
PROJECTIONS IN THE
WELDING PROCESS
THE WELDING START IS
VERY AGGRESSIVE.
THERE ARE MANY
PROJECTIONS.
D1 D3
E01 THE Overheating has occurred in the power source. The thermal protection has disconnected the equipment.
E02 OVT It is detected that there is no welding voltage.
E03 OVC Over current.
E04 CON No communication between the frontal electronic board and the control one.
E06 GND Earth failure.
E07 OVV Over-voltage of input power supply (U1>470 V).
E08 UNV Under-voltage of input power supply (U1>330 V).
E09 NPH Phase failure in the power supply line.
E10 REF Lack of coolant pressure.
SPECIALIZED PERSONNEL MUST CARRY OUT ANY WORK ON THE EQUIPMENT.
BOTH AT THE BEGINNING AND END OF A REPAIR CHECK THE EQUIPMENT INSULATION LEVELS.
DISCONNECT THE ELECTRONIC BOARDS WHEN MEASURING THE INSULATION.
BLOW THE INSIDE OF THE EQUIPMENT WITH COMPRESSED AIR.
The insulation-measuring device will have 500 V D.C. and will be applied to the following points of the circuit:
- Supply-Earth: Ra > 50 Mohms.
- Welding-Earth: Ra > 50 Mohms.
- Supply-Welding: Ra > 50 Mohms.
BEFORE TURNING THE EQUIPMENT ON, ENSURE THAT IT IS OFF LOAD.
DO NOT OPERATE THE ON/OFF SWITCH WITH AN ELECTRICAL LOAD

PROBABLE CAUSE.
Unsuitable shielding gas.
Excessive driving pressure.
Filler material is dirty or oxidized.
Insufficient arc length correction.
Inappropriate dinamic adjustment (tendency
to negative)
Stick out or insufficient distance between
nozzle and base material.
Earth contact faulty.
Base material and filler material are too
"cold".
Aluminium is being welded with a drawing
problem, which causes incorrect arc ignition
as the wire is slowed down on knocking
against the piece.
The wire length at onset of welding process
is too long.
Oxide or other polluting agents are present
in base material.
CONNECTED TO THE WELDING CONNECTORS.
POSSIBLE SOLUTION.
When welding normal steels we advise the use of a gas
mixture Ar-CO2.
Reduce the tightening knob pressure.
Remove remains of impurities, oils, oxides, etc.
Increase the arc correction factor. (E1 control)
Adjust the dinamic control from "SETUP" mode.
Increase the distance between torch and material to be
welded.
Ensure the earth tap adjustment.
To reduce the abruptness at first of weld, please use the
4SS striking mode.
Examine the drawing process. Prevent the gun from
making "knots", keeping it in a straight line. The wire
must not be slowed down when it knocks against the
piece
Change in the settings menu the value of the burn-back
time correction.
Ensure the cleanig of material to be welded.
