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 posi-
tioning of parts, the replacement of wire and underflushing opera-
tions etc. This welder is dimensioned to supply a I
current in complete safety for a period of work of 20% of the to-
tal usage time. The regulations in force establish the total usage
time to be 10 minutes. The work cycle is considered to be 20% of
this period of time. If the permitted work cycle 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 overheat cut-off rearms automatically (and the
yellow LED turns itself off) and the welder is ready for use again.
This generator is constructed in compliance with the IP 23 S pro-
tection level, meaning:
• That it is protected against the penetration of solid foreign bod-
ies 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 carrying
it by hand.
NOTE: These hoisting and transportation devices conform to Eu-
ropean standards. Do not use other hoisting and transportation
systems.

Open the packaging

The system essentially consists of:
• RAINBOW 183 cell vrd weld unit.
• Accessory kit comprising clamp and earth cables, a brush-ham-
mer 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 bod-
ies are blocking the air circulation.

Installation

The installation site for the system must be carefully chosen in or-
der to ensure its satisfactory and safe use.
Before installing the system the user must take into consideration
the potential electromagnetic problems in the work area. In particu-
lar, 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.
The welder must not be rested on a slant of more than 10°.
These welding machines are cooled through air forced-circulation.
That is why they must be disposed to facilitate the suction and the
emission of air through the slots of the frame.
The welding unit is characterized by the following classes:
• IP 23 S protection class indicates that the generator can be used
in both interior and exterior environments.
• The "S" usage class indicates that the generator can be em-
ployed in environments with a high risk of electrical shocks.

Connection to the electrical supply

Before connecting the welder to the electrical supply, check
that the machine's plate rating corresponds to the supply volt-
age 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 mak-
ing the "EARTH" connection.
Connect a suitable load of normalised plug (2p + e) to the
power cable and provide for an electrical socket complete
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 supply
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 suitable
diameter, and absolutely not of a smaller diameter than the spe-
cial 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 voltage.
