2 GENERAL DESCRIPTIONS

2.1 SPECIFICATIONS
The MultiMig 522 is an equipment suitable for synergic
pulsed MIG/MAG, synergic not pulsed MIG/MAG and
conventional MIG/NAG welding, developed with inverter
technology. The power source is equipped with a 2-roller
wire feeder.
This welding machine must not be used to defrost pipes.
2.2 EXPLANATION OF TECHNICAL SPECIFICATIONS
N°. Serial number. Must be indicated on any
request regarding the welding machine.
Single-phase
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 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
capacity of the fuse (delayed type) to be used
as a protection for the equipment.
IP21S Protection rating for the housing.
static transformer-rectifier
S
Suitable for use in high-risk environments.
NOTE: The welding machine has also been designed for
use in environments with a pollution rating of 3.
(See IEC 60664).
2.3 PROTECTIONS
2.3.1 Block protection
In the event of a malfunction, a flashing number may
appear on the display AM, 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
electrode and the material to be welded.
Shut the machine off and turn it back on. If different
numbers appear on the display, contact technical service.
2.3.2 Overload cut-out
This machine is protected by a thermostat, which prevents
the machine from operating if the allowable temperatures
are exceeded. In these conditions the fan continues to
operate and the display AM flashes the abbreviation "tH."
3 DESCRIPTION OF POWER SOURCE (Fig. 1)
A – Socket (-): this is where the earth cable is to be
connected.
B – Central adapter : Connect the welding torch.
B1 – Central adapter.
This is where the welding torch or the Push-Pull system
torch (EL900005) is to be connected.
C – Connector : For connecting remote controls and the
welding control cable Push–Pull (EL900005).
D - Selector switch:
Central adapter B1 is operated by selecting position
( ) with the selector switch knob, on the contrary, by
selecting position (
F - Connector : Connector type DB9 (RS232 serial line) to
use for updating the microprocessor programs.
L - ON/OFF switch.
M – Power cable.
N – Gas hoses.
) central adapter B is operated.
