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.
5.1 Connections and control devices
Connecting control cable
When connecting the control cable, it is
important to secure the cable with the
load-removing grommet.
Ensure that the cover is properly screwed
into place.

5.2 Explanation of function
Wire feed speed
This sets the required feed speed of the filler wire in m/minute.
2 stroke
With 2-stroke, the gas flow starts followed by the wire feed when the trigger switch is
pressed in. The welding process is concluded when the trigger switch is released,
the wire feed stops and the gas stops flowing.
4 stroke
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.
Spot welding
Spot welding is used when you want to weld on short, repeated occasions with a
pre-set time.
When the trigger switch is pressed in, the gas flow starts for a period of time
governed by the printed circuit board. After this the welding process starts for the set
time. When the welding process is complete, the gas flow stops.
Cold wire feed
Cold wire feed is used to feed wire without welding voltage and gas flow.
Activation of cold wire feed: press in the trigger switch and the wire feed starts.
Gas purging
Gas purging is used to measure that 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.
Activation of gas purging: press in the trigger switch and gas purging starts.
Burnback time
Burnback time is a delay between the time when the wire brakes 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 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 50% lower speed until it comes into
electrical contact with the workpiece, at which point the speed increases to the set
speed.

5.3 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).
5.4 Replacing and inserting wire
WARNING
Risk of crushing when replacing the wire bobbin!
Do not use safety gloves when inserting the welding wire between the feed rollers.
S Open the side panel.
S Disconnect the pressure sensor by folding it backwards, the pressure arm is
folded up.
S Straighten out 10-20 cm of the new wire. File away 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 Fold down the pressure arm and secure it to the pressure sensor.
S Close the side pannel.

5.5 Changing feed roller Feed L302
S Open the side panel.
S Disconnect the pressure sensor (1) by folding it
backwards.
S Disconnect and remove the Allen screw (2) and the
washer.
S Pull out the feed roller (3).
During installation, repeat the above in the reverse
order.
Choice of track in the feed roller
Turn the feed roller with the dimensioning mark for the
required track towards you.
5.6 Changing feed roller Feed L304
S Open the side panel.
S Disconnect the pressure sensor (1) by folding it
backwards.
S Disconnect the feed rollers (2) by unscrewing the
nuts (3) and pulling out the rollers.
During installation, repeat the above in the reverse
order.
Choice of track in the feed roller
Turn the feed roller with the dimensioning mark for the
required track towards you.
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.

The brake hub
The hub is adjusted when delivered, if
readjustment is required, follow the instructions
below. Adjust the brake hub so that wire is slightly
slack when wire feed stops.
S Adjusting the braking torque:
S Turn the red handle to the locked position.
S Insert a screwdriver into the springs in the hub.
Turn the springs clockwise to reduce the braking torque
Turn the springs counter-clockwise to increase the braking torque. NB: Turn
both springs the same amount.
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.
Feed L302 / Feed L304 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.
