2.3 DESCRIPTION OF PROTECTIVE DEVICES
2.3.1 Thermal protection
This machine is protected by a thermostat, which prevents
the machine from operating if the allowable temperatures are
exceeded. In this condition the display will show the error
code E1.

3 INSTALLATION

Only skilled personnel should install the machine. All con-
nections must be carried out according to current regula-
tions, and in full observance of safety laws (regulation CEI
26-10 - CENELEC HD 427).
1. Place the welding machine in a stable and safe position.
Air must circulate freely, both incoming and outgoing,
and the welding machine must be protected from entry
by liquids, dirt, metal filings, etc.
2. Make sure that the supply voltage matches the voltage
indicated on the specifications plate of the welding
machine. When mounting a plug, make sure it has an
adequate capacity, and that the yellow/green conductor
of the power supply cable is connected to the earth pin.
The capacity of the overload cutout switch or fuses
installed in series with the power supply must be equiv-
alent to the absorbed current I1 of the machine.
Any extension cords must be sized appropriately for the
absorbed current I1.
