1 GENERAL DESCRIPTIONS

1.1 SPECIFICATIONS
Before using this device all people authorised to its
use, repair or inspection, should read the book
"Safety rules for using
"Instruction manual" specific for every machine.
Contact your distributor if you have not understood

1.3 BEFORE CONNECTING THE WELDING MACHINE
Before connecting and switching on the unit follow all
safety rules and instructions as indicated in this manual.
Make sure that the airflow on cooling slots
obstructed and then proceed as follows :
1) Unpack the machine.
2) Take care that the unit is not placed before a wall or
in a position which might cut off the air; moreover, do
not cover the unit's source with plastic materials,
metal or paper sheets because they cause the
decrease of the airflow.
3) Make sure that the air temperature does not exceed
+40°C.
4) Do not place any filtering device over the intake air
passages of this welding machine.
Warranty is void if any type of filtering device is used.
2 INSTALLATION
2.1 SET-UP
All connections must be made in compliance with current
regulations and in full respect of safety laws (see
CENELEC HD 427 standard).
Assemble the parts supplied with the welding machine.
To lift the machine use the two upper eyebolts, placing
the ropes as shown in fig.1.
The handle must NOT be used for lifting.
