DESCRIPTION OF THE MACHINE

REV.0-01/16

The engine driven welder is a unit which ensures the function as:

a) a current source for are welding

b) a current source for the auxiliary generation

The welding generator set is a source of DC electric power, driven by an internal combustion engine, which

allows to perform arc welding processes with different types of electrodes and, with the CC/CV version,

also wire welding. Besides, the generation set can provide ac 50 Hz auxiliary power, both three-phase

and single phase, usable for the various needs associated with the welding. The engine which drives the

generator set is a two-cylinder diesel type, air cooled, while the alternator is an asynchronous three-phase

type. The welding current control is performed by means of a high frequency (20 kHz) “Chopper System”

, while the regulation board is implemented with analogue technology.

From a mechanical viewpoint, the machine is composed of a bunded basement and a roll-bar, which sup-

port the engine-alternator assembly. The canopy includes a protection cover for the front panel and two

lateral doors intended to allow the routine maintenance operations. For the extraordinary maintenance

the canopy can be removed in a fairly simple way.

On the front panel there are the engine protection unit (EP7) and the welding control unit (WAC). Loca-

ted on EP7 there are the start key and a few indicator lights which monitor the engine status. The WAC

hosts the regulation knob of the welding current (which regulates also the welding voltage in the CC/CV

version) and the arc force knob. The auxiliary power sockets and the welding sockets are also placed on

the front panel.
