General description
The machine has been specially designed for extracting
and/or filtering fumes and gases that are released
during the most common light and medium welding
processes.
With its wheels, the handle and its compact design the
machine is extremely suited to be used in relatively
small workshops or near sources of pollution without a
fixed location.
4.2
Operation
The machine works in accordance with the
recirculation principle.
The extracted fumes pass the air intake and enter the
pre-separator in which primary filtration takes place
and where sparks, if any, are separated. Subsequently
the air passes the prefilter and the main filter, in which
most of the fume particles are filtered out. Finally, the
fan blows the air into the HEPA filter where the
remaining fumes are separated. The cleaned air is
returned into the workshop via the outlet grid. With the
optional hose connection HCH-45 the air can be
discharged elsewhere, for example into the
atmosphere.
The welding fumes can be extracted at source in the
following ways:
A by the supplied extraction hose Ø 45 mm
connected to the welding torch

;
B by the supplied extraction hose Ø 45 mm
connected to the extraction nozzle
