protective glass according to standards (degree of
protection DIN 10).
- warn people in the vicinity not to look directly at
the arc.
PREVENTION OF FIRE
Welding produces splashes of molten metal.
Take the following precautions to prevent fire:
- ensure that there is a fire extinguisher in the
welding area.
- remove all inflammable material from the
immediate vicinity of the welding area.
- cool the welded material or let it cool before
touching it or putting it in contact with combustible
material
- never use the machine for welding containers of
potentially inflammable material. These containers
must be completely cleaned before they are
welded.
- ventilate the potentially inflammable area before
using the machine.
- do not use the machine in atmospheres
containing high concentrations of powders,
inflammable gases or combustible vapours.
GENERAL
CHARACTERISTICS
This new series of welding machines with
electronic
regulation
controlled
by
a
microprocessor ,allows you to achieve excellent
welding
quality,
thanks
to
the
advanced
technologies applied. The microprocessor circuit
controls and optimises the transfer of the arc
irrespective of the load variation and of the
impedance of the welding cables.
The controls on the front panel allow easy
programming of the welding sequences depending
on the operating requirements.
The inverter technology used has allowed the
following to be obtained:
- machines with extremely low weight and compact
dimensions;
- reduced energy consumption ;
- excellent dynamic response;
- very high power factor and yields;
- better welding characteristics;
- viewing of the data and of the set functions on the
display.
The electronic components are enclosed in a
sturdy structure that is easy to carry and cooled
with forced air by fans with low noise production.
N.B. This welding machine is not suitable for
thawing pipes.
