(*) Mains supply Zmax: maximum impedance value allowed for the grid

WARNING: This equipment does not comply with EN/IEC 61000-3-12.
If it is connected to a public low voltage system, it is the responsibil-
ity of the installer or user of the equipment to ensure, by consultation
with the distribution network operator if necessary, that the equipment
may be connected.
Usage limits (IEC 60974-1)
The use of a welder is typically discontinuous, in that it is made
up of effective work periods (welding) and rest periods (for the
positioning of parts, the replacement of wire and underflushing
operations etc. This welder is dimensioned to supply a I2max
nominal current in complete safety for a period of work of 25%
of the total usage time. The regulations in force establish the
total usage time to be 10 minutes. The work cycle is consid-
ered to be 25% of this period of time. If the permitted work cy-
cle time is exceeded, an overheat cut-off occurs to protect the
components around the welder from dangerous overheating.
Intervention of the overheat cut-off is indicated by the lighting
up of yellow thermostat LED. After several minutes the over-
heat cut-off rearms automatically (and the yellow LED turns it-
self off) and the welder is ready for use again. This generator
is constructed in compliance with the IP 23 S protection lev-
el, meaning:
•
That it is protected against the penetration of solid foreign
bodies with diameters in excess of Ø 12 mm.
•
That it is protected against water spray hitting the surface
with an angle of incidence up to 60°.
• That the welding machine has been tested for withstanding
harmful effects due to water getting in when the moving parts
on the equipment are moving.
Installation
The installation site for the system must be carefully chosen in
order to ensure its satisfactory and safe use.
The user is responsible for the installation and use of the sys-
tem in accordance with the producer’s instructions contained
in this manual.
Before installing the system the user must take into consider-
ation the potential electromagnetic problems in the work area.
In particular, we suggest that you should avoid installing the
system close to:
• Signalling, control and telephone cables.
• Radio and television transmitters and receivers.
• Computers and control and measurement instruments.
• Security and protection instruments.
Persons fitted with pace-makers, hearing aids and similar
equipment must consult their doctor before going near a ma-
chine in operation. The equipment’s installation environment
must comply to the protection level of the frame i.e. IP 23 S
(IEC 60529 publication). The system is capable of working in
environments where working conditions are particularly hard.
This system is cooled by means of the forced circulation of air,
and must therefore be placed in such a way that the air may
be easily sucked in and expelled through the apertures made
in the frame.
Connection to the electrical supply
Before connecting the welder to the electrical supply,
check that the machine’s plate rating corresponds to the
supply voltage and frequency and that the line switch of
the welder is in the “O” position.
Use the welder’s own plug to connect it up to the main pow-
er supply. Proceed as follows if you have to replace the plug:
•
2 conducting wires are needed for connecting the machine
to the supply
•
The third, which is YELLOW GREEN in colour is used for
making the “EARTH” connection.
PROJECT 1800 HF works with circuit breaker or fusible pow-
er switches.
Table 2 shows the recommended load values for retardant sup-
ply fuses.

NOTE 1: Any extensions to the power cable must be of a suit-
able diameter, and absolutely not of a smaller diameter than
the special cable supplied with the machine.
NOTE 2: It is not advisable to plug up the welder to motor-driv-
en generators, as they are known to supply an unstable volt-
age.
