Before using the equipment you should
carefully read the instructions included in this
manual. In order to get the best performance
6
from the system and ensure that its parts last
as long as possible, you must strictly follow the
usage instructions and the maintenance
6
regulations included in this manual. In the
interest of customers, you are recommended
to have maintenance and, where necessary,
6
repairs carried out by the workshops of our
service organisation, since they have suitable
equipment and specially trained personnel
7
available. All our machinery and systems are
subject to continual development. We must
therefore reserve the right to modify their
8
construction and properties.
Description
8
Rainbow 180 is the latest evolution in inverter
8
technology generators for welding.
The most advanced materials and components
have been used to design and produce it such
as:
9
• Main planar transformer with extremely low
load loss
• Electronic auxiliary feeder
9
• Voltage doubler ensuring precision striking,
constant arc and very low electrical input
from the main supply by the welder
9
• Extremely high frequency power INVERTER
with very latest type of IGBT to reduce
switching losses to a minimum
9
• High electric efficiency (> 0,8)
• Selector with 3 weld procedures
• Basic electrodes with "hot start" and "arc
51
force" device
• Stainless steel electrodes with special
characteristics for a soft arc
52
• TIG welding with thermal controlled (TCS)
"lift" type striking reducing tungsten
inclusions to a minimum and allowing to
53
also strike on sharp edges
The generator also conforms to all European
Union standards and directives in force

The general technical data of the system are
summarized in table 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 12 max 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 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 signal
light. After several minutes the overheat cut-
off rearms automatically (and the yellow signal
light turns itself off) and the welder is ready for
use again. Do not weld in the rain. This
generator is constructed in compliance with the
IP 23 protection level.
GENERAL SAFETY STANDARDS
These products must be used for
welding and not for other improper
uses. Their use is permitted only by
trained and experienced persons.
The operator must observe the CEI 26.9 HD
407 safety standards in order to guarantee his
safety and that of third parties.
