SEnsure your working stance is safe.

FUMES AND GASES -- Can be dangerous to health

SKeep your head out of the fumes.

SUse 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.

SProtect your eyes and body. Use the correct welding screen and filter lens and wear protective

clothing.

SProtect bystanders with suitable screens or curtains.

FIRE HAZARD

SSparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.

NOISE -- Excessive noise can damage hearing

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!

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

5 INSTALLATION

The installation must be executed by a professional.

WARNING!

This product is intended for industrial use. In a domestic environment this product may cause radio

interference. It is the user’s responsibility to take adequate precautions.

WARNING!

When welding in an environment with increased electrical danger, only power sources intended

for this environment may be used. These power sources are marked with the symbol .

5.1 Terminating resistor

The ends of the CAN bus must be fitted with terminating

resistors to avoid communication interference.

The terminating resistor is delivered with the power source.

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

has an integral terminating resistor. The other end is at

the wire feed unit and must be fitted with the

terminating resistor, as shown on the right.

6 OPERATION

General safety regulations for the handling of the equipment can be found on

page 3. Read through before you start using the equipment!

WARNING!

Assure that the side panels are closed during operation.

WARNING!

Rotating parts can cause injury, take great care.

Symbol and function explanations

Inlet spatter removal air (10)

Shielding gas (13)

Outlet spatter removal air (6)

Used for spray--cleaning the contact tip on the welding gun.

Gas purging (2)

Used to measure the gas flow or to flush the gas hoses to clean them of any air and

moisture before commencing welding. Gas purging is carried out with the voltage

and wire feed switched off.

Reversed wire feed (3)

Used to reverse the wire, for example when replacing the wire bobbin.

Inching (4)

Used when wire is to be fed without switching on the welding voltage.

6.2 Gas flow guard (if installed)

The gas flow monitor interrupts the ongoing welding process if the gas flow drops

below 3.5 l/min. When this occurs, an error message is displayed via the control unit.

6.3 Wire feed pressure

Start by making sure that the wire moves smoothly through the wire guide. Then

set the pressure of the wire feeder’s pressure rollers. It is important that the

pressure is not too great.

Fig 1 Fig 2

To check that the feed pressure is set correctly, you can feed out the wire against

an insulated object, e.g. a piece of wood.

When you hold the gun approx. 5 mm from the piece of wood (fig. 1) the feed

rollers should slip.

If you hold the gun approx. 50 mm from the piece of wood, the wire should be

fed out and bend (fig. 2).

6.4 Replacing and inserting wire

SOpen the side panel.

SDisconnect the pressure sensor by folding it backwards, the pressure rollers

slide up.

SStraighten out the new wire 10--20 cm. File away burrs and sharp edges from the

end of the wire before inserting it into the wire feed unit.

SMake sure that the wire goes properly into the feed roller’s track and into the

outflow nozzle or wire guide.

SSecure the pressure sensor.

SClose the side panel.

6.5 Changing feed rollers

SOpen the side panel.

SDisconnect the pressure sensor (1) by folding it

backwards, the pressure rollers slide up.

SDisconnect the pressure rollers (2) by turning the

axle (3) 1/4 turn clockwise and pulling out the axle.

The pressure rollers disconnect.

SDisconnect the feed rollers (4) by unscrewing the nuts

(5) and pulling out the rollers.

During installation, repeat the above in the reverse order.

Choice of track in the feed rollers

Turn the feed roller with the dimensioning mark for the required

track towards you.

7 MAINTENANCE

Regular maintenance is important for safe, reliable operation.

Note!

All guarantee undertakings from the supplier cease to apply if the customer himself

attempts any work in the product during the guarantee period in order to rectify any

faults.

7.1 Inspection and cleaning

Wire feed unit

Check regularly that the wire feed unit is not clogged with dirt.

SCleaning and replacement of the wire feed unit mechanism’s worn parts should

take place at regular intervals in order to achieve trouble--free wire feed. Note

that if pre--tensioning is set too hard, this can result in abnormal wear on the

pressure roller, feed roller and wire guide.

Welding gun

SCleaning and replacement of the welding gun’s wear parts should take place at

regular intervals in order to achieve trouble--free wire feed. Blow the wire guide

clean regularly and clean the contact tip.

8 ORDERING SPARE PARTS

RoboFeed 3004w is designed and tested in accordance with the international and Eu-

ropean standards IEC/EN 60974--5 and 60974--10. It is the obligation of the service unit

which has carried out the service or repair work to make sure that the product still

conforms to the said standard.
