This device is a generator inverter current (DC) suitable to
the MMA welding. 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 rutile and can be connected to power
generators with power equal to or higher than that
reported in Table 2. It is equipped with "HOT START",
"ARC FORCE" and "ANTI STICK” functions (for more
details please refer to the GENERAL PART manual
included in the package).

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.

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 1,
C and D) rotating the attack in order to ensure a good grip.
Choose the polarity

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 1, E) to the
ON position.
•
Select the welding current (FIG 1, A) as a function
of the type of electrode selected (Tab. 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

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.
