1.3 Disconnect input plug or power before working on
machine.
2
Breathing welding fumes can be hazardous to your
health.
2.1 Keep your head out of fumes.
2.2 Use forced ventilation or local exhaust to remove
fumes.
2.3 Use ventilating fan to remove fumes.
3
Welding sparks can cause explosion or fire.
3.1 Keep flammable materials away from welding.
3.2 Welding sparks can cause fires. Have a fire extingui-
sher nearby and have a watchperson ready to use it.
3.3 Do not weld on drums or any closed containers.
4
Arc rays can burn eyes and injure skin.
4.1 Wear hat and safety glasses. Use ear protection and
button shirt collar. Use welding helmet with correct
shade of filter. Wear complete body protection.
5
Become trained and read the instructions before
working on the machine or welding.
6
Do not remove or paint over (cover) label.
2 GENERAL DESCRIPTIONS
2.1 SPECIFICATIONS
This welding machine is a power source developed with
inverter technology, suitable for MIG, TIG and MMA weld-
ing.
This welding machine must not be used to defrost pipes.
2.2 EXPLANATION OF TECHNICAL SPECIFICATIONS
This machine is manufactured according to the following
standards: IEC 60974.1 / IEC 60974.10 (CL. A) /
IEC 61000-3-11 (see note 2) / IEC 61000-3-12.
N°.
Serial number. Must be indicated on any
request regarding the welding machine.
Single-phase static transformer-rectifier
frequency converter.
MIG Suitable for MIG-MAG welding.
MMA Suitable for welding with covered eletrodes.
TIG Suitable for TIG welding.
U0.
Secondary open-circuit voltage.
X.
Duty cycle percentage. The duty cycle
expresses the percentage of 10 minutes
during which the welding machine may run
at a certain current without overheating.
I2.
Welding current
U2.
Secondary voltage with current I2
U1.
Rated supply voltage
1~ 50/60Hz 50- or 60-Hz single-phase power supply.
I1 Max
Max. absorbed current at the corresponding
current I2 and voltage U2.
I1 eff
This is the maximum value of the actual
current absorbed, considering the duty cycle.
This value usually corresponds to the capaci-
ty of the fuse (delayed type) to be used as a
protection for the equipment.
IP23S
Protection rating for the housing.
Grade 3 as the second digit means that this
equipment may be stored, but it is not
suitable for use outdoors in the rain, unless
it is protected.
Suitable for use in high-risk environments.
S
Note:
1- The machine has also been designed for use in envi-
ronments with a pollution rating of 1. (See IEC 60664).
2- This equipment complies with IEC 61000-3-11 provided
that the maximum permissible system impedance Zmax
is less than or equal to 0,459 at the interface point
between the user's supply and the public system. It is the
responsibility of the installer or user of the equipment to
ensure, by consultation with the distribution network
operator if necessary, that the equipment is connected
only to a supply with maximum permissible system
impedance Zmax less than or equal to 0,459.
2.3 PROTECTIONS
2.3.1 Block protection
In the event of a malfunction, a flashing number may
appear on the display M, with the following meaning:
52 =
Start button pressed during start-up.
53 =
start button pressed during thermostat reset.
56 =
Extended short-circuit between the welding elec-
trode and the material to be welded.
Shut the machine off and turn it back on. If different num-
bers appear on the display, contact technical service.
2.3.2 Overload cut-out
This machine is protected by a thermostat, which pre-
vents the machine from operating if the allowable tem-
peratures are exceeded. In these conditions the fan con-
tinues to operate and the display M flashes the abbrevi-
ation "tH."
3 CONTROLS ON THE FRONT PANEL.
Selection key V.
Each brief pressure selects the size, adjustable
via the knob I. The values that may be selected
are in relation to the type of welding process selected,
and are displayed on the LEDs A/B/C/D. Holding the key
down for more than three seconds will open the "service
functions" menu. Within the "service functions," holding
the button down returns the selected function to the man-
ufacturer setting; pressing it briefly confirms the changes
made and returns to welding.
LED A Current. Indicates that the display M shows
the reset welding current. Active in all welding
processes.
LED B
Wire speed. Indicates that the display M
shows the MIG welding wire speed.
LED C Thickness. The display M shows the recom-
mended thickness based on the current and wire
speed set for MIG welding.
LED D PROG.
Selected via the button V , and using the knob I sets:
The numbers of the programs for MIG welding and TIG
and MMA welding processes.
