SYMPTOM. ANOMALY.
THERE ARE MANY
PROJECTIONS IN THE
WELDING PROCESS
THE WELDING START IS VERY
AGGRESSIVE.
THERE ARE MANY
PROJECTIONS.
D1 D3
Overheating has occurred in the power source. The thermal protection has disconnected the
E01 THE
equipment.
E02 OVT It is detected that there is no welding voltage.
E03 OVC Over current.
E04 CON Lack of communication between the front electronic board and control electronic board
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.
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 dynamic 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.
BLOW THE INSIDE OF THE EQUIPMENT WITH COMPRESSED AIR.
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 dynamic 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 4TS
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 (see section 3.6.2).
Ensure the cleaning of material to be welded.
