WARNING

Read and understand the instruction manual before installing or operating.

Arc welding and cutting can be injurious to yourself and others. Take precautions when welding and

cutting. Ask for your employer's safety practices which should be based on manufacturers' hazard

data.

ELECTRIC SHOCK - Can kill

S Insulate yourself from earth and the workpiece.

S Ensure your working stance is safe.

FUMES AND GASES - Can be dangerous to health

S Keep your head out of the fumes.

S 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.

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

clothing.

S Protect bystanders with suitable screens or curtains.

FIRE HAZARD

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

NOISE - Excessive noise can damage hearing

S Protect your ears. Use earmuffs or other hearing protection.

S Warn bystanders of the risk.

MALFUNCTION - Call for expert assistance in the event of malfunction.

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 those locations, due to conducted

as well as radiated disturbances.

MIG/MAG welding with robotic equipment.

The wire feed unit consists of a drive unit (RoboFeed 3004HW) and a separate

electronic unit (FeedControl 3004HW).

NOTE!

The wire feed unit utilizes the robot's safety system to obtain maximum interference protection.

ESAB's accessories for the product can be found on page 22.

4 INSTALLATION

The installation must be carried out by a professional.

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

4.1 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 (U8

2

), which

has an integral terminating resistor.

The other end is at the FeedControl and must be fitted with

the terminating resistor, as shown on the right.

If U8

2

is used together with W8

2,

the terminal resistor in

the W8

2

must be disconnected, see the instruction

manual for the W8

2.

4.2 Example of a robotic welding system

Note! A mounting kit and a cable kit are required for mounting to a robot, please

contact your local ESAB dealer for more information.

Symbol and function explanations

Inlet spatter removal air

Shielding gas

Outlet spatter removal air

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

Gas purging

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.

Inching

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

Shielding gas out

5.2 Replacing and inserting wire

S Open the side panel.

S Disconnect the pressure sensor by folding it backwards, the pressure rollers

slide up.

S Straighten out the new wire 10-20 cm. File off any burrs and sharp edges from

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

S Make sure that the wire goes properly into the feed roller's track and into the

outflow nozzle or wire guide.

S Secure the pressure sensor.

S Close the side panel.

WARNING

Risk of crushing when replacing the wire bobbin!

Do not use safety gloves when inserting the welding wire between the feed rollers.

5.3 Changing feed rollers

S Open the side panel.

S Disconnect the pressure sensor (1) by

folding it backwards, the pressure rollers

slide up.

S Disconnect the pressure rollers (2) by

turning the axle (3) 1/4 turn clockwise and

pulling out the axle. The pressure rollers

disconnect.

S Disconnect the feed rollers (4) by

unscrewing the nuts (5) and pulling out the

rollers.

During installation, repeat the above in the

reverse order.

5.4 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 MAINTENANCE

Regular maintenance is important for safe, reliable operation.

CAUTION

All guarantee undertakings from the supplier cease to apply if the customer attempts any

work to rectify any faults in the product during the guarantee period.

6.1 Inspection and cleaning

Wire feed unit

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

S Cleaning 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

S The welding gun's wear parts should be cleaned and replaced at regular

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

regularly and clean the contact tip.

7 ORDERING SPARE PARTS

Repair and electrical work should be performed by an authorised ESAB service

technician. Use only ESAB original spare and wear parts.

RoboFeed 3004HW is designed and tested in accordance with the international and

European standards IEC/EN 60974-5 and IEC/EN 60974-10. It is the obligation of the

service unit which has carried out the service or repair work to make sure that the pro

duct still conforms to the said standard.

Spare parts may be ordered through your nearest ESAB dealer, see the last page of

this publication.
