PROTECT YOURSELF AND OTHERS!
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 such locations, due to conducted as
well as radiated disturbances.
NOTE!
Dispose of electronic equipment at a recycling
facility!
To conform with the European Directive 2012/19/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.
CAUTION!
Read and understand the instruction manual before
installing or operating.
ESAB can provide you with all necessary welding protection and accessories.
W82is a control unit and it exists in two different chassis:
2.1Equipment
Aristo® W8
2
W82is a control unit that adjusts the communication between
welding equipment and automation equipment, such as robots and
computers. Communication protocols: DeviceNet, Profibus,
CANopen and Ethernet.
W82is used together with ESAB's CANbus equipped power sources
for welding automation. For power source and wire feed unit
handling, see the relevant instruction manual.
Retrofit Aristo® W8
2
Retrofit Aristo® W82is retrofitted on top of supported ESAB power
sources. It connects to the CANbus internally. Communication
protocol: WeldLink.
For information about supported power sources, contact your ESAB
sales representative.
Aristo® W8
2
•W82DeviceNet, W82Profibus, W82CANopen and W82Ethernet are supplied with USB
memory and an instruction manual.
•W82Integrated is supplied with an instruction manual.
Retrofit Aristo® W8
2
•Retrofit Aristo® W82is supplied with the WeldLink software and an instruction manual.
Measurement cable kit and connection cables for different power sources are available as
accessories, see "ACCESSORIES" chapter and separate spare parts list.
Instruction manuals in other languages can be downloaded from the Internet:
The installation must be carried out by a professional.
See the service manual for Aristo® W82.
4.1Electrical supply
NOTE!
Mains supply requirements
High power equipment, due to the primary current drawn from the mains supply,
may 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, in consultation
with the distribution network operator if necessary, that the equipment may be
connected.
4.2Assembly instruction
Connection of Aristo® W82 to ESAB's Mig 5000i power source
1. Remove the rear handle of the welding
power source by removing the screws.
2. Put the W82onto the welding power
source.
3. Screw the W82and the handle into place
in the same screw holes.
Connection of Retrofit Aristo® W82
For instructions on how to connect the Retrofit Aristo® W82, see the Service manual for W8
or contact the nearest ESAB Service Center or distributor.
Connection of Aristo® W82 to ESAB's Mig 3001i, Mig 4001i and Mig 6502c power
sources
Connect the W82with a 6.5ft (2 m) cable and place it on the floor or on a stand next to the
power source.
It is possible to configure the U82unit for standalone usage (standalone unit) or presentation
usage (presentation unit). The presence of a W82unit within the welding system determines
which unit is to be used.
The standalone unit is used when there is
no W82unit in the system.
The presentation unit is used when there
is a W82unit in the system.
It is necessary to convert the U82standalone unit to a U82presentation unit before it is used
together with a W82unit.
During unit startup it is possible to see whether or not the unit is a presentation unit.
4.4How to setup the U82 for use with W82
NOTE!
It is necessary to change the U82stand-alone unit to a presentation unit before it
can be used together with a W82unit.
4.4.1Save your stored data
1.Connect the U82standalone unit to a power source or a wire feed unit.
2.Turn on the power source's main switch.
3.Export weld data sets from the U82memory to USB memory (see chapter Export/Import
in the U82instruction manual).
General safety regulations for handling the equipment can be found in the "SAFETY"
chapter of this manual. Read it through before you start using the equipment!

attempts any work to rectify any faults in the product during the warranty period.
6.1Inspection and cleaning
Regularly check that the control unit is in electrical contact with the power source and that
the connections are fault free and connected correctly.
W82is designed and tested in accordance with the international and European
standards 60974-1 and 60974-10. It is the obligation of the service unit that carried out
