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.

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.
