VOLTAGE CHANGE
All the equipment from the GALA INDUSTRIAL
series have two voltages (standard version at
230/400 V). Therefore it is necessary to check that
the voltage selected on the equipment coincides
with the mains voltage.

2.2. INSTALLATION OF AUTO-COOLED MODULATE MIG SYSTEM (WITHOUT COOLING).
The wire-feed unit must be connected to the power source. Fig. 4 describes the installation process of GALA
INDUSTRIAL equipment without cooling.
The connection is made with the connection extension A (see table 4). The installation is comprised of the
following elements:
B- CONTROL hose.
C- Shielding GAS line.
D- POSITIVE supply pole.
E- Shielding gas hose.
F- Pressure reducing valve.
G- Welding torch.
H- Earth taps.
M- Welding earth clamp.
N- Power supply hose
O- Connection plug.

E, which is connected to the rear of the power source.
The gas flow can be controlled with the pressure
reducing valve F to a recommended value between 10
and 12 l/min. (wide range depending on wire)
letter H. We must place earth J to a tap, which will be
chosen depending on the thickness to be welded (see
section 3.1).
Standard equipment leaves the factory with the
voltage selected at 400 V.
voltage place screw T in position 2. To connect the
equipment move indicator to 230 V position.
DO NOT FORGET TO FIT THE EARTH
CONNECTION INTO THE PLUG.
MAKE SURE THE MAINS VOLTAGE
COINCIDES WITH
THAT ESTABLISHED IN THE MACHINE.
