INTRODUCTION
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).

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.
ELECTRODE WELDING (MMA)
•
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 Fig.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

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.

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.
MAINTENANCE
The all maintenance services must be done from qualified
personnel in compliance to the norm (IEC 60974-4).
