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.

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.
