equipment. Incorrect operation of the equipment may lead to hazardous situations which can
result in injury to the operator and damage to the equipment.
1. Anyone who uses the equipment must be familiar with:
○ its operation
○ location of emergency stops
○ its function
○ relevant safety precautions
○ welding and cutting or other applicable operation of the equipment
2. The operator must ensure that:
○ no unauthorised person is stationed within the working area of the equipment

WARNING!
Arc welding and cutting can be injurious to yourself and others. Take precautions
when welding and cutting.
ELECTRIC SHOCK - Can kill
• Install and ground the unit in accordance with instruction manual.
• Do not touch live electrical parts or electrodes with bare skin, wet gloves or
wet clothing.
• Insulate yourself from work and ground.
• Ensure your working position is safe
ELECTRIC AND MAGNETIC FIELDS - Can be dangerous to health
• Welders having pacemakers should consult their physician before welding.
EMF may interfere with some pacemakers.
• Exposure to EMF may have other health effects which are unknown.
• Welders should use the following procedures to minimize exposure to EMF:
○ Route the electrode and work cables together on the same side of your
body. Secure them with tape when possible. Do not place your body
between the torch and work cables. Never coil the torch or work cable
around your body. Keep welding power source and cables as far away
from your body as possible.
○ Connect the work cable to the workpiece as close as possible to the
area being welded.
FUMES AND GASES - Can be dangerous to health
• Keep your head out of the fumes.
• Use ventilation, extraction at the arc, or both, to take fumes and gases
away from your breathing zone and the general area.
ARC RAYS - Can injure eyes and burn skin
• Protect your eyes and body. Use the correct welding screen and filter lens
and wear protective clothing.
• Protect bystanders with suitable screens or curtains.
NOISE - Excessive noise can damage hearing
Protect your ears. Use earmuffs or other hearing protection.

source.
4.2 System description
It is possible to configure the U8
2
unit for stand-alone usage (stand-alone unit) or
presentation usage (presentation unit). The presence of a W8
2
unit within the welding system
determines which unit that is to be used.
4 INSTALLATION

The stand-alone unit is used when there is
no W8
2
unit in the system.
The presentation unit is used when there
is a W8
2
unit in the system.
During unit start-up it is possible to see if the unit is a presentation unit or not.
4.3 How to set-up the U82 for use with W82
NOTE!
It is necessary to change the U8
2
stand-alone unit to a presentation unit before it
is used together with a W8
2
unit.
4.3.1 Save your stored data
1. Connect the U8
2
stand-alone unit to a power source or a wire feed unit.
2. Turn ON the main switch on the power source.
3. Export weld data sets from the U8
2
memory to a USB memory (see chapter
Export/Import in the U8
2
instruction manual).
4. Turn OFF the main switch on the power source.
5. Remove the USB memory.
4.3.2 Convert the U82 stand alone unit to a presentation unit
1. Connect the enclosed USB memory to a PC. Make sure that the computer is set to show
file extensions.
2. Rename: "update.txt_" to "update.txt" and "reset.txt_" to "reset.txt"

7. Arc voltage monitoring (-), black banana socket
8. Fieldbus Connection for communication with robot system
9. Ethernet connection
5.2 Overheating protection
The control unit has overheating protection that operates if the temperature becomes too
high. When this occurs the welding current is interrupted and the orange lamp illuminates.
The overheating protection resets automatically when the temperature has fallen and the
light goes out.
5.3 Arc voltage feedback
To achieve a good welding result, the arc voltage feedback is a crucial factor. In MIG/MAG
welding, the power source is prepared to sense the arc voltage in the wire feeder.
Prerequisite for this functionality is that an ESAB wire feeder and an ESAB interconnection
cable is used! This method of measuring the arc voltage, compensates for the voltage drop
in the welding cable to the wire feeder. With an ESAB torch supporting "TrueArcVoltage", the
voltage drop all the way to the contact tip is compensated.

WARNING!
The external arc voltage inputs (the red and black banana sockets) at the back
end of the WeldCloud™ top box should not be used, unless the equipment has
been configured for this setup by authorised ESAB service personnel.
NOTE!
To compensate the voltage drop in the return cable, the power source can be
configured (by authorised ESAB service personnel) to use an external arc voltage
sense wire from the workpiece.
