PRESENTATION
INVERTER TECHNOLOGY
These current generators with inverters are
designed to work under unstable voltages.
The use of power components and elec-
trolytic condensers with higher voltage and a
particular control circuit ensure high stability
of the welding current even in the event of
power variations. These inverters allow for
welding with coated electrodes (MMA - DC)
and using scratch start, with infusible electro-
des (TIG - AC/DC), some equipped with HF.
Thanks to the technology used in their ma-
nufacturing, the generators make it particu-
larly easy to use the two MMA-TIG functions
right from the start. These inverter generators
consist of a power control board, a switching
transformer and an impedance. The board
includes several electronic functions to im-
prove the arc trigger and the dynamic action
of the welding, in order to obtain perfect wel-
dings with both applications.
An IGBT bridge ensures quick reaction and
maximum accuracy, together with a remar-
kable reduction of the magnetic components.
As a consequence, the weight of the genera-
tor is reduced. All these features, other than
their low power consumption, make these ge-
nerators perfect for all kinds of welding. They
are also equipped with a handle for easy mo-
vement.
For satisfying results, and in accordance with
all safety standards, users must be familiari-
zed with:
MMA (DC) and TIG (AC/DC) welding;
Regulation of welding parameters;
Welding performance.
