3.1 MAINS FEATURES AND TECHNICAL DATA
3. OVERALL FEATURES
The new inverter GLOBUS175HF and Globus 225HF have been designed to
work with unstable input voltages. The use of power components and of
electrolytic capacitors with higher voltage and a special control circuit grant
a high welding current stability in spite of the mains voltage fluctuations. This
units allow coated electrode (MMA) welding by scratch starting tungsten inert
gas (TIG) welding with or without HF. The technology used to manufacture
the generators, combined to both MMA and TIG functions, makes them
particularly easy to be used since the beginning. The generators are composed
by a control and power p.c. board, by a switching transformer and a levelling
inductance. In the p.c.board are included different electronic functions in order
to improve the arc striking and the dynamic of the welding, so that we can
achieve an optimum weld with any type of electrode and top simplicity of
performance.
An IGBT bridge guarantees a fast speed of response and greater precision,
together with a drastic reduction of all magnetic components with a consequent
great reduction of the generator weight. All the above characteristics, including
a handle that enable the unit to be carried easily, and the low electricity
consumption, make these generators ideal for all types of welding applications.
In order to obtain satisfactory results, in conformity with all safety standards,
the operator should have a good knowledge of the following:
Stick/Tig process.
Welding parameter adjustments .
