INTRODUCTION
This device is a generator inverter current (DC) suitable to
weld Fig. B-0. Thanks to the inverter technology, which
allows achieving high performances while keeping small
size and weight, the welder is portable and easy to handle.
The device is suitable for welding with coated electrodes
(Tab.B-1) and can be connected to power generators with
power equal to or higher than that reported in Table B-2.

INSTALLATION
The installation must be made by trained personnel in
compliance to the standard IEC 60974-9 and the current
and local legislation. To lift the machine it must be used
the handle positioned on top of the product with the
machine in OFF position. The input voltage must match
the voltage indicated on the technical plate located on the
product.
Use the machine on electric system having supply features
and power protection (fuse and / or differential
switch)
that are compatible with the current required for its use. For
more details see the information on the plate placed on the
machine.
HOW USE IT
Warning: Use all precautions required in the safety
general manual before operating the welder, reading
carefully the risks linked to the welding process.
•
Connect the plugs of the earth clamp and the
electrode holder to the connectors of the machine (Fig
B-
1, C and D) rotating the attack in order to ensure a
good grip. Choose the polarity
Fig.B-2
(
1.
forward or
2.
reverse) depending on the coating of the electrodes (for
more information see the information on the electrodes
packaging).
•
Connect the earth clamp to the work piece to be
welded trying to establish a good point of contact between
the metal and the clamp, as close as possible to the area
to be welded, insert the electrode into the electrode
holder.
•
Insert the plug into the power outlet and turn on the
welding machine by pressing the switch (Fig
B-
1, E) to
the ON position.
For welding machines without a plug
(115/230V models), connect a normalised plug (2P + T) -
having sufficient capacity- to the power cable and prepare a
mains outlet fitted with fuses or an automatic circuit-breaker;
the special earth terminal should be connected to the earth
conductor (yellow-green) of the power supply line.
•
Select the welding current (FIG
B-
1, A) as a function
of the type of electrode selected (Tab.
B-
1).
•
Start the welding operation using all the necessary
protections for the security.
•
When welding is completed, turn off the machine
and release the electrode from the electrode holder
THERMAL PROTECTION
If the machine is used for hard work cycle, the thermal
protection device will protect the machine from over
heating. The yellow LED ON indicates that the thermal
protection is on. It is possible to start welding again once
the LED is off.
(Fig. B-1, B)
MAINTENANCE
The all maintenance services must be done from qualified
personnel in compliance to the norm (IEC 60974-4).
ANOMALIES
CAUSES
REMEDIES
The device is not delivering current
and the yellow indicator LED of
thermal protection lights up.
The welder thermal
protection has turned on.
Wait for the end of the cooling
time, around 2 minutes. The
indicator led turns off.
The device is on but it is not
delivering current.
The cable of the earth
clamp or electrode holder
is not connected to the
welder.
Turn off the machine and check the
connections.
Your unit does not weld correctly.
Polarity error
Check the polarity advised on the
electrodes packaging.
TROUBLESHOOTING
ELECTRODE WELDING (MMA)
TIG WELDING (only for the TIG type)
•
Connect the connectors of the earth clamp and of the torch
to the poles of the device; choose the polarity (forward or
reverse) in relation to the type of material to be welded
Connect the earth clamp to the work piece
Connect the torch gas tube to the gas cylinder (Fig.B-3)
Select the TIG mode
Select the welding current
Select the gas flow of the gas cylinder and open the torch
valve
Connect the power cord to the power supply and turn on
the welder
Use the torch to weld as in the following without a puse
between the two phases
Touch the piece with the electrode
Lift the electrode from the piece
about 2-5 mm
Stopped the welding, turn off the machine
Instable arc
-)Default coming from the
tungsten electrode
-)Too important gas flow
rate
-) Use a tungsten electrode with the
adequate size
-) Reduce gas flow rate
The electrode melts
