Engine driven welders designated with the acronym “DSP” - Digital Signal Processor -
represent a new generation of engine driven machines, which operate at high frequency.
The control of the welding processes is done by a microcomputer (DSP) using patented MOSA
software, which controls the welding current or welding voltage cycle by cycle.

The high speed of the DSP allows almost instantaneous control of welding parameters,
translating into a highly stable output current or welding voltage.

DSP engine driven welders have only four main components: a chopper diode bridge, the

The optional polarity change consists of a power change-over switch and of a special program
for the polarity change-over.
