3 INTRODUCTION

The Feed 302 wire feed unit with control panel M11 is

intended for MIG/MAG--welding together with step

controlled welding power sources.

They come in different variants, see the spare parts list on

page 13.

The wire feed units are sealed and contain two--wheel

drive wire feed mechanisms as well as control electronics.

They can be used together with wire on ESAB’s

MarathonPact, or on wire bobbin (standard Ø 300 mm, accessory Ø 440 mm).

The wire feed unit can be installed either at the power source, suspended above the

workplace, on a support arm or on the floor with or without wheel set.

ESAB’s accessories for the product can be found on page 16.

3.1 Equipment

The Feed 302 wire feed unit is supplied with:

SInstruction manual

SStickers with recommended wear parts.

Instruction manuals in other languages can be downloaded from the website,

Duty cycle

The duty cycle refers to the time as a percentage of a ten--minute period that you can weld at a cer-

tain load without overloading. The duty cycle is valid for 40˚C.

Enclosure class

The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid

objects or water. Equipment marked IP23 is designed for indoor and outdoor use.

Equipment marked IP2X is designed for indoor use.

5 INSTALLATION

The installation must be executed by a professional.

CAUTION!

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 Lifting instructions

Ordering number for the lifting eye can be found on page 16.

Note! If another mounting device is used, this should be insulated from the wire feed

unit.

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!

To prevent the reel from sliding off the hub: Lock the

reel in place by turning the red knob as shown on the

warning label attached next to the hub.

WARNING!

Rotating parts can cause injury, take great care.

WARNING!

There is a risk of tipping if the wire feed unit is fitted with a counterbalance arm.

Secure the equipment, especially if used on an uneven or sloping surface.

NOTE! When moving the equipment use intended handle. Never pull on the gun.

wer source (cooling unit)

5Connection BLUE, with ELP* for cooling

water to the welding gun 11 Connection BLUE for cooling water from

6Connection RED for cooling water from

welding gun 12 Connection for shielding gas

NOTE! Cooling water connections only available on certain models.

* ELP = ESAB Logic Pump, see point 6.2.

6.2 Water connection

When connecting a water--cooled welding gun, the power source’s main power

supply switch must be in the Off position and the cooling unit switch must be in

position “ELP/0”.

The wire feed unit with water connection is equipped with a detection system ELP

(ESAB Logic Pump) which checks that the water hoses are connected. When

connecting a water--cooled welding gun, the water pump starts.

Detection only works with power sources that are equipped with ELP.

6.3 Function explanations

Burnback time

Burnback time is a delay between the time when the wire starts to brake until the

time when the power source switches off the welding voltage. Too short burnback

time results in a long wire stickout after completion of welding, with a risk of the wire

being caught in the solidifying weld pool. Too long a burnback time results in a

shorter stickout, with increased risk of the arc striking back to the contact tip.

Creep start

Creep start means that the wire is fed at low speed until it comes into electrical

contact with the workpiece and then the speed increases to the set speed.

2stroke

With 2 stroke, the gas flow and wire feed start when the trigger switch is pressed in

and end when it is released.

4stroke

With 4 stroke, the gas flow starts when the trigger switch is pressed in and the wire

feed starts when it is released. The welding process continues until the switch is

pressed in again, the wire feed stops and when the switch is released the gas stops

flowing.

Wire feed speed

This sets the required feed speed of the filler wire in m/minute.

6.4 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).

6.5 Changing / loading 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.

6.6 Changing feed roller

SOpen the side panel.

SDisconnect the pressure sensor (1) by folding it

backwards, the pressure rollers slide up.

SCompletely undo the socket head cap screw

(2) in the centre.

SRemove the washer.

SCompletely undo the two outer socket head cap screws

(3).

SPull out the feed rollers (4).

During installation, repeat the above in the reverse order.

Choice of tracks in the feed roller

Turn the feed roller with the dimensioning mark for the required track towards you.
