5.0 TRANSPORT - UNLOADING

Never underestimate the weight of the equip-
ment, see technical characteristics.
Never make the cargo pass or leave it suspended
over people or things.
Neither let the equipment or the single unit fall,
nor put it down with force.
Once it has been removed from the packing, the
power source is supplied with an belt which can be
used to move it in the hand.

6.0 INSTALLATION

Choose an adequate installation area by following
the criteria provided in Section "1.0 SAFETY" and
"2.0 ELECTROMAGNETIC COMPATIBILITY (EMC)".
Do not position the power source and the equip-
ment on surfaces with inclination exceeding 10°
with respect to the horizontal plane.
Protect the installation from heavy rain and sun.

6.1 Electric connection to the supply mains

The equipment is provided with a single electric connection with
a 2m cable positioned in the rear part of the power source.
Size table of the power source input cables and fuses:
Rated voltage 115 V ± 15%
Voltage range 98 - 133 V
Delayed fuses* 16 A 250 V
Power supply cable 3x1,5 mm2
*: Fuses with a 20A rating are required to be able to carry out
100 A electrode welding continuously and to make maximum
use of the potential of the power source. 16 A fuses are suffi-
cient for welding, with a normal use factor (40%).
WARNING
* The electrical system must be made by skilled technicians
with the specific professional and technical qualifications
and in compliance with the regulations in force in the
country where the equipment is installed.
* The welding power source supply cable is provided with a
yellow/green wire that must ALWAYS be earthed. This yel-
low/green wire must NEVER be used with other voltage
conductors.
* Verity the existence of the earthing in the used plant and
the good condition of the socket/s
* lnstall only plugs that are homologated according to
the safety regulations.

6.2 Connecting the equipment components

Connection for MMA welding

7.0 PROBLEMS - CAUSES

230 V ± 15%
195,5 - 264,5 V

7.1 Possible faults in the MMA welding

16 A 250 V
3x1,5 mm2
Fault
Excessive spatter
Craters
Inclusions
Insufficient penetration
Sticking
Blow-hole and porosity
Cracks
Keep to the safety regulations contalned in section
"1.0 SAFETY".
Connect the componente carefully, in order to
avoid power losses.
The connection shown in the figure produces
reverse polarity welding. To obtain straight polarity
welding, invert the connection.
Fig.3
Cause
1) Long arc
2) High current
1) Fast movement of the
electrode away from piece.
1) Poor cleanliness or distri-
bution of the passes
2) Defective movement of
the electrode
1) High progression speed
2) Welding current too low
3) Narrow chamfering
4) Deseaming failure on top
1) Arc too short
2) Current too low
1) Humidity in electrode
2) Long arc
1) Current too high
2) Dirty materials
3) Hydrogen in weld
(present on electrode
coating)
