DSP 600 PS

Diesel Engine driven welder - PERKINS 1103A - 33G1 Engine -  Three-phase asyncronous alternator  - Three-phase generation 30 kVA - Single-phase generation 15 kVA - Max welding current: 600A

The engine-driven welder DSP 600 PS is a professional machine with digital adjustment of the welding parameters DSP (Digital Signal Processor) and welding circuit with Chopper 
System (high frequency 20 kHz). Equipped with a Perkins series 1103 diesel engine and an asynchronous alternator, it can be used simultaneously as a welder and as a three-phase and single-phase electrical generator.

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:

  1. 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.
  2. 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.
  3. 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.

The DSP 600 PS is a super-silent engine-driven welder with compact canopy, suitable for a wide range of applications, including large metal fabrications, oil pipelines and use in construction sites.

DSP Program

sample powersafe TECHNOLOGY

The acronym DSP, which is referred to this line of MOSA welders, stands for "Digital Signal Processor", and identifies the fact that the regulation of the welding parameters is performed by means of a digital technique. More precisely, in the DSP controller reside the programs which perform the regulation of the different welding processes supported.

The implementation of the control is accomplished by a power converter of the "Chopper" type (Chopper Technology), which operates at high frequency (20 kHz).

The high frequency conversion allows to obtain superior welding performances in comparison with more conventional techniques at low frequency.

FEATURES

Via a rotary selector you can choose between 5 different welding programs.

  1. LIFT ARC TIG – This program performs  a TIG welding with a "Lift Arc" start. With this feature the arc is started simply by touching the piece, without scratch.
  2. STICK (3 PROGRAMS) - They are specific for the electrode welding (CC), being characterized by three different arc force levels with increasing short circuit current from 1 to 3.
  3. MIG MAG – It is dedicated to WIRE welding, WITH GAS or FLUX CORED. This welding process is performed at constant voltage (CV).

The front panel of the DSP control unit is provided with a military type circular connector which can be connected to a MOSA remote control unit or wire feeder, for MIG MAG. When plugging an external connector the control is automatically switched from the front panel knob to the knob on the remote unit. All the machines of this series are equipped with digital meters to monitor the welding current and voltage. The software of the control unit, depending on the version of welder on which it is installed, can handle various functions, including:

a) Power Optimizer - A function that prevents overloading of the engine during welding
b) VRD - (Voltage Reduction Device) a function that reduces the open circuit voltage to a safe value when  not welding
c) Reverse polarity – In the models where this function is present , a switch on the panel commands the contactor which implements the polarity reversal.

The DSP controller also implements some security features:
  • Chopper converter overtemperature
  • Overcurrent during welding (due to failure or malfunction)
  • Current sensor not connected
  • Malfunction of the supply voltage
