SProtect your ears. Use earmuffs or other hearing protection.

SWarn bystanders of the risk.

MALFUNCTION - Call for expert assistance in the event of malfunction.

PROTECT YOURSELF AND OTHERS!

WARNING

Do not use the power source for thawing frozen pipes.

CAUTION

Read and understand the instruction manual before

installing or operating.

CAUTION

This product is solely intended for arc welding.

CAUTION

Class A equipment is not intended for use in residential locations where

the electrical power is provided by the public low-voltage supply system.

There may be potential difficulties in ensuring electromagnetic

compatibility of class A equipment in those locations, due to conducted

as well as radiated disturbances.

Dispose of electronic equipment at the recycling facility!

In observance of European Directive 2002/96/EC on Waste Electrical and Electronic

Equipment and its implementation in accordance with national law, electrical and/or

electronic equipment that has reached the end of its life must be disposed of at a

recycling facility.

As the person responsible for the equipment, it is your responsibility to obtain

information on approved collection stations.

For further information contact the nearest ESAB dealer.

ESAB can provide you with all necessary welding protection and accessories.

2 INTRODUCTION

The Mig U4000i is a MIG/MAG / TIG welding power source, which can also be used

for MMA welding.

The power source is 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.

ESAB's accessories for the product can be found on page 21.

Duty cycle

The duty cycle refers to the time as a percentage of a ten-minute period that you can weld or cut at

a certain load without overloading. The duty cycle is valid for 40°C.

Enclosure class

The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid

objects or water. Equipment marked IP23 is designed for indoor and outdoor use.

Application class

The symbol indicates that the power source is designed for use in areas with increased

electrical hazard.

4 INSTALLATION

The installation must be carried out by a professional.

Note

Mains supply requirements

High power equipment may, due to the primary current drawn from the mains supply, influence the

power quality of the grid. Therefore connection restrictions or requirements regarding the

maximum permissible mains impedance or the required minimum supply capacity at the interface

point to the public grid may apply for some types of equipment (see technical data). In this case it

is the responsibility of the installer or user of the equipment to ensure, by consultation with the

distribution network operator if necessary, that the equipment may be connected.

4.1 Lifting instructions

Power source Trolley and power source Trolley2 and power source

4.2 Placing

Position the welding power source such that its cooling air inlets and outlets are not

obstructed.

4.3 Mains power supply

Check that the unit is connected to the correct mains power

supply voltage, and that it is protected by the correct fuse sizes.

A protective earth connection must be made, in accordance

with regulations.

NB:

The mains cable areas and fuse sizes as shown above are in accordance with

Swedish regulations. They may not be applicable in other countries: make sure that

the cable area and fuse sizes comply with the relevant national regulations.

4.4 Terminating resistor

In order to avoid communication interference, the ends

of the CAN bus must be fitted with terminating

resistors.

One end of the CAN bus is at the control panel, which

has an integral terminating resistor. The other end at

the power source must be fitted with the terminating

resistor, as shown on the right.

4.5 Connection of multiple wire feed units

With control unit and wire feed units without control panel it is possible to manage up

to 4 wire feed units from one power source.

It is possible to choose between the following connections:

S1 TIG-torch and 1 MIG-gun (Universal power source required)

S2 MIG/MAG-guns

S1 TIG-torch and 3 MIG/-guns (Universal power source required)

S4 MIG/-guns

When welding with water-cooled MIG/-guns on all wire feed units, it is recommended

to connect a separate cooling unit for the 2 extra guns.

We recommend connecting the guns in parallel.

Two wire feed units

A connection kit is required when connecting two wire feed units, see accessories on

page 21.

Four wire feed units

Two connection kits and an extra cooling unit are required when connecting four wire

feed units, see accessories on page 21.
