1.2 Safety precautions

NOTE!

The unit is tested by ESAB in a general set-up. The responsibility for safety and

function, of the specific set-up, lies with the integrator.

Users of ESAB equipment have the ultimate responsibility for ensuring that anyone who

works on or near the equipment observes all the relevant safety precautions. Safety

precautions must meet the requirements that apply to this type of equipment. The following

recommendations should be observed in addition to the standard regulations that apply to

the workplace.

All work must be carried out by trained personnel well-acquainted with the operation of the

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

when it is started up

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

unit for stand-alone usage (stand-alone unit) or

presentation usage (presentation unit). The presence of a W8

unit within the welding system

determines which unit that is to be used.

4 INSTALLATION

0460 971 301

- 10 -

The stand-alone unit is used when there is

no W8

unit in the system.

The presentation unit is used when there

is a W8

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

stand-alone unit to a presentation unit before it

is used together with a W8

unit.

4.3.1 Save your stored data

1. Connect the U8

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

memory to a USB memory (see chapter

Export/Import in the U8

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"

4 INSTALLATION

3. Open the cover on the left-hand end of the

control panel.

4. Insert the enclosed USB-memory into the

USB connector.

5. Close the cover.

6. Turn ON the main switch on the power

source. One “beep” indicates that convert

process is started. It is finished when two

“beeps” are heard.

7. Turn OFF the main switch on the power

source.

8. Open the cover and remove the enclosed

USB memory.

9. Close the cover. The unit is now ready to be used together with a W8

unit.

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.

5 OPERATION

0460 971 301

- 15 -

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.

6 MAINTENANCE
