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
The Inverter power source supplies adjustable
continuous current to provide maximum cutting
performance.
The Inverter has been designed with the latest
advanced technology available, providing the
following advantages:
- Low weight to allow maximum ease of handling.
- The inverter technology allows a stable arc to be
obtained, which ensures high cutting quality for a
great variety of metals and thicknesses.
- The pilot arc can perforate painted or rusty
metals.
- The continuous pilot arc allows easy cutting of
perforated materials; the pilot arc is transferred to
the piece that is to be cut when the torch is about 3
mm. away from the cutting surface.
- The regulating potentiometer, positioned on the
front panel, sets the cutting current of the machine.
- The Inverter operates with compressed air .
The air used must be free from impurities, oil or
other polluting substances.
