READ THIS FIRST

Maintenance and repair work must 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 boards

are divided into numbered blocks, which are described individually in more detail in the

description of operation. Component names in the wiring diagram are listed in the

component description.

Use the spare parts list as a guide to where the components are located in the equipment.

The spare parts list is published as a separate document, see the "SPARE PARTS" chapter

in this manual.

This manual contains details of design changes that have been made up to and including

August 2018.

The manual is valid for:

• Mig U5000i and Mig 5000i with serial no. 803- and 950-xxx-xxxx

• Mig U5000i WeldCloud™ and Mig 5000i WeldCloud™ with serial no. 608-, 613- and

834-xxx-xxxx

NOTE!

Mig U5000i and Mig 5000i with serial numbers 304-, 445-, 524-, 620-, 640- and

802-xxx-xxxx differ from the description in this manual. For those power sources

there is another service manual with file name 0740 800 158.

The Mig 5000i and Mig 5000i WeldCloud™ are designed and tested in accordance with

international and European standards IEC/EN 60974-1 and IEC/EN 60974-10. On

completion of service or repair work, it is the responsibility of the person(s) performing the

work to ensure that the product still complies with the requirements of the above standard.

The Mig 5000iw and Mig 5000iw WeldCloud™ are designed and tested in accordance with

international and European standards IEC/EN 60974-1, IEC/EN 60974-2 and IEC/EN

60974-10. On completion of service or repair work, it is the responsibility of the person(s)

performing the work to ensure that the product still complies with the requirements of the

INTRODUCTION

The Mig U5000i and Mig U5000i WeldCloud™ are MIG/MAG welding current power

sources, which can also be used for MMA and HF-TIG welding. The Mig 5000i and Mig

5000i WeldCloud™ can be used for MIG/MAG and MMA welding.

There are two variants of the Mig 5000i and Mig 5000i WeldCloud™ power sources: with

cooling unit or without cooling unit. This service manual describes a power source with

cooling unit.

The Mig U5000i and Mig U5000i WeldCloud™ power sources are available with a cooling

unit.

The power sources are intended for use with the Feed3004 or Feed4804 wire feed units. All

the settings are made from the wire feed unit or control box U8 or U8

2

.

Design structure of the power source

The power source is transistor-controlled, operating on the inverter principle. It consists of a

number of function modules, as shown in the block diagram on next page. Each module has

a module number, which is always included as the first part of the name/identification of

components in the module. The modules have the following main functions:

1 MMC module

The control panel and welding data unit, which control the power source functions.

2 Mains module

Mains interference suppressor, mains switch, auxiliary transformer, contactor.

15 Power module

This module is a dual forward converter inverter, operating at a switching frequency of 2 × 27

kHz. IGBT transistors are used as the switching elements. All power semiconductors are built

into modules in order to ensure a robust design suitable for use in the demanding welding

environment.

20 Processor board module (controler module)

This is the controller board, 20AP1, with a microprocessor, that monitors and controls the

voltage and current. It is served by relay board 20AP2, which handles input and output

signals to/from the controller board. Further information on the modules can be found in the

component and function descriptions.

Block diagram of the power source

WeldCloud™

For information about WeldCloud™, see WeldCloud™ instruction manual.

The WeldCloud™ unit connects the welding power source to a remote WeldCloud™ server

through Wi-Fi, Wired LAN or 3G. The WeldCloud™ unit can have a GPS unit to track the

location of the welding power source.

The WeldCloud™ unit Wi-Fi is enabled after power up of the power source. It will start as a

hotspot with a default hotspot name. This hotspot appears as an available Wi-Fi network.

After establishing the connection, it is possible to access the web interface of the power

source.

CAUTION!

STATIC ELECTRICITY can damage circuit boards and

electronic components.

• Observe precautions for handling electrostatic

sensitive devices.

• Use proper static-proof bags and boxes.

MMC option for MIG power sources

The CAN bus distribution board connected to a Mig 5000i.

The MIG power sources are normally delivered without MMC module. If the accessory 'MMC

kit' is used, the MMC module can be moved from the wire feed unit to the power source.
