READ THIS FIRST
Maintenance and repair work should be performed by an experienced person, and
electrical work only by a trained electrician. Use only recommended replacement parts.
This service manual is intended for use by technicians with electrical/electronic training for
help in connection with fault--tracing and repair.
Use the wiring diagram as a form of index for the description of operation. The circuit
board is divided into numbered blocks, which are described individually in more detail in
the description of operation. All component names in the wiring diagram are listed in the
component description.
This manual contains details of all design changes that have been made up to and
including December 2010.
The Origo
TM
Mig 4002cw, Mig 4002c, Mig 5002cw, Mig 5002c, Mig 6502cw, Mig 6502c
are designed and tested in accordance with European standard EN 60974--1 and EN
60974--10.
On completion of service or repair work, it is the responsibility of the person(s) etc.
performing the work to ensure that the product does not depart from the requirements
of the above standard.
WARNING
Many parts of the power unit are at mains voltage.
INTRODUCTION
The Origo
TM
Mig 4002cw, Mig 5002cw, Mig 6502cw are MIG/MAG welding power
sources, which can also be used for MMA welding.
There are two variants of the power sources:
S Origo
TM
Mig xx02c without cooling unit
S Origo
TM
Mig xx02cw with cooling unit
The power sources are intended for use with the Aristo
TM
Feed 3004 or Aristo
TM
Feed 4804 wire feed units.
All the settings are made from the wire feed unit.
