Description

Mosa DSP 500 YS CC/CV Diesel Welder Generator

The DSP 500 YS CC/CV is an Italian made 500A industrial water cooled diesel welder generator.  A constant current and constant voltage (CC/CV) machine, the DSP 500 YS is suitable for stick welding, carbon arc gouging and running a wire feed unit for MIG welding too.

A 60 litre fuel tank allows 19 hour running time and 3 auxiliary sockets are equipped providing single and 3 phase power, perfect for running lighting, grinders and other site equipment.

Features WDC (Welding digital control) and designed for rigorous welding applications. This welder generator is from a range of heavy duty, multi process welder-generators, made by MOSA. Heavy duty construction with a solid chassis and roll bar, also with a long run time on one tank of fuel. Offers 5 welding programmes for contact TIG DC, MMA Stick with 3 Arc Force settings including cellulose pipe electrodes plus a programme for CV MIG welding using the optional MOSA WF4 wire feed unit.

The engine driven Mosa welder DSP 500 YS is a Constant Current (CC), Constant Voltage (CV) professional machine with electronic control of the welding current.  CC and CV welding output modes are selectable:

  • In Constant Current (CC) Mode, it is possible to choose between a characteristic with adjustable arc force, suitable for MMA and TIG welding (With Scratch Start).
  • In Constant Voltage (CV) mode it is possible to MIG weld using the optional WF4 Mosa Wire Feed Unit.  Capable of Wire welding both Solid and Flux Cored wires.

 

The DSP range of engine driven welders operate at high frequency using the Digital Signal Processor. The welding voltage or current is controlled, cycle by cycle,using patented technology. An innovative microcomputer within the machine is programmed with this sophisticated software.  This DSP technology creates an extremely stable output of welding current or voltage by almost instantaneous control of the welding parameters.

All of this is achieved using just four main components; A HALL sensor very accurately measures the welding current, a small reactance and a chopper diode bridge which is controlled by the digital welding control.

There is also a power change-over switch which allows for polarity change if this is a desired option. A special programme makes this possible.

The DSP series provides a very high quality welding output. Very few component parts reduces the number of required connections to a minimum so increasing this output further more.

Suggested applications for this engine driven welder include; mining and quarrying, pipeline construction, ship repair & construction, steel fabrication and construction, steel fabrication and construction, refinery and petrochemical construction, heavy plant maintenance and shutdown.

The Welding Digital Control functions include; GTAW (Gas Tungsten Arc Welding – TIG), SMAW (Sheilded Metal Arc Welding), GMAW (Gas Metal Arc Welding – MIG), FCAW (Flux Cored Arc Welding).

The Mosa DSP series welder generators are a complete power solution. Mains welding or cutting machines can be powered directly from this DSP series of machine driven welders using AC Multi voltage auxiliary power.

TECHNOLOGY

FEATURES

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

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.
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.
MIG MAG – It is dedicated to WIRE welding, WITH GAS or FLUX CORED. This welding process is performed at constant voltage (CV).

 

Mosa DSP 500 YS Control Panel

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
