2 GENERAL DESCRIPTIONS

The welding machine is a system suitable for synergic
MIG/MAG and pulsed synergic MIG/MAG welding, devel-
oped with inverter technology. It is equipped with a 4-roll-
er gearmotor.This welding machine must not be used to
defrost pipes.

2.1 EXPLANATION OF TECHNICAL SPECIFICATIONS

This machine is manufactured according to the following
international standards:
IEC 60974-1 / IEC 60974-5 / IEC 60974-10 (CL. A) / IEC
61000-3-11 / IEC 61000-3-12.
No. Serial number. Must be indicated on any re-
quest regarding the welding machine.

frequency converter.
MIG Suitable for MIG/MAG welding.
U0. Secondary open-circuit voltage.
X. Duty cycle percentage.
The duty cycle expresses the percentage of
10 minutes during which the welding ma-
chine may run at a certain current without
overheating.
I2. Welding current
U2. Secondary voltage with I2 current
static transformer-rectifier
U1. Rated supply voltage.
3~ 50/60Hz Three-phase 50 or 50 Hz power supply.
I1 Max Max. absorbed current at the corresponding
I2 current and U2 voltage.
I1 eff This is the maximum value of the actual cur-
rent absorbed, considering the duty cycle.
This value usually corresponds to the capac-
ity of the fuse (delayed type) to be used as a
protection for the equipment.
Protection rating for the housing. Grade 3
IP23S
as the second digit means that this machine
may be stored, but it is not suitable for use
outdoors in the rain, unless it is protected.
S
Suitable for use in high-risk environments.
NOTE:
The equipment has also been designed for use in environ-
ments with a pollution rating of 3. (See IEC 60664).

2.2 PROTECTION DEVICES

2.2.1 Block protection
In case of welding machine malfunction, the display
screen A will show the message WARNING to identify the
type of fault. If this message does not disappear when the
machine is switched off and back on, contact the after-
sales service.
2.2.2 Thermal cutout
This welding machine is protected by a thermostat
which prevents machine operation whenever acceptable
temperatures are exceeded. In these conditions, the fan
continues to operate and the display screen A shows the
message WARNING tH in flashing mode.
2.2.3 Positioning on sloping planes.
Since this welding machine is equipped with wheels
without brake, do not position it on sloping planes, to
prevent machine tilting or uncontrolled movement.
