Technical data

The general technical data of the system are summarized in
table 1.
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 I
nominal current in complete safety for a period of work of 20%
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 20% 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.
How to lift up the machine
This welding machine has a handle for picking it up and car-
rying it by hand.
NOTE: These hoisting and transportation devices conform to
European standards. Do not use other hoisting and transpor-
tation systems.

Open the packaging

The system essentially consists of:
• RAINBOW 180 weld unit.
• Accessory kit comprising clamp and earth cables, a brush-
hammer and a protective screen (optional).
• Neck strap / bag for carrying the welding machine (optional).
Upon receiving the system:
• Remove the welding generator and all relative accessories
and components from the packaging.
• Check that the weld machine is in good condition, if not report
any problems immediately to the seller-distributor.
• Make sure all ventilation grilles are open and that no foreign
bodies are blocking the air circulation.
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:
max
2
• 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). 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.
This system has been designed for nominal voltage 230 V -
50/60 Hz. It can however work at 220 V and 240 V - 50/60 Hz
without any problem. Connection to the power supply must be
carried out using the tripolar cable supplied with the system,
of which:
• 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.
Connect a suitable load of normalised plug (2p + e) to the
power cable and provide for an electrical socket com-
plete with fuses or an automatic switch. The earth terminal
must be connected to the earth conducting wire (YELLOW-
GREEN) of the supply.
Table 2 shows the recommended load values for retardant sup-
ply fuses chosen according to the maximum nominal current
supplied to the welder and the nominal supply voltage.
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.
