The engine-driven welder DSP 500 PS is a professional multi process machine with digital adjustment of the welding parameters DSP (Digital Signal Processor) and welding circuit with Chopper System (high frequency 20 kHz) capable of delivering up to 500 A with a duty cycle of 60%.
Equipped with a Perkins series 400 water cooled diesel engine and an asynchronous alternator, it can be used simultaneously as a welder and as a three-phase and single-phase electrical generator up to 20 kVA.
Thanks to the lower engine speed (1500 rpm) it is suitable for continuous operation in all conditions. Designed to meet the requirements of professional welding in direct current, a selector switch allows the operator to choose between 5 different welding programs:
- LIFT ARC TIG – TIG welding by controlling start-up in "Lift Arc" mode. The arc begins with a simple contact of the electrode on the workpiece and lifting the tungsten electrode from the workpiece initiates the arc without inclusion.
- MMA STICK (3 PROGRAMS) – Specific for MMA ELECTRODE (CC) welding, they offer three different levels of arc force, with increasing short-circuit currents including cellulosic.
- MIG MAG – Dedicated to SOLID WIRE OR FLUX-CORED WELDING, providing employing a constant voltage (CV) welding process with optional MOSA WF4 Wire Feed Unit.
