Lincoln Electric LINC FEED 22 Manuel D'utilisation page 11

Take precaution to keep eyes and hands away from the
end of the torch while feeding wire.
Once the wire has finished feeding through the welding
gun turn the wire supply off before replacing to contact
tip and gas diffuser.
Welding with MIG / MAG method in
Manual mode
To begin welding process with MIG/MAG method in
manual mode you should:
•
Switch ON the machine which supplies the wire
feeder.
•
Insert the electrode wire into the torch using "Cold
Inch" switch [15].
•
Check gas flow with "Gas Purge" switch [15].
•
Set knob [11] (only LF 24 PRO) in Manual position
(verify that the panel [4] has lit the Manual mode).
•
According to selected welding mode and material
thickness set the proper welding voltage and the
wire feeding speed with WFS knob [2].
•
Obeying the appropriate rules, you can begin to
weld.
Welding Source Select (only LF 24
PRO)
The wire feeder LF 24 PRO can work with below power
sources in synergic mode:
•
Powertec 300S.
•
Powertec 360S.
•
Powertec 420S.
•
Powertec 500S.
The feeder is set for co-operation with Powertec 420S
(factory default).
If it is necessary to change the power source, you
should:
•
Switch the supply of the wire feeder off.
•
Set the knob of the choice wire diameter selection
[10] in "1.6 CORE" position. Set the knob of the
choice welded material and gas mixture [11] in
"MANUAL" position.
•
Switch the supply of the wire feeder on.
•
Within 15s switch the knob of the choice wire
diameter selection [10] in "0.8" position and the
knob of the choice welded material and gas mixture
[11] in "STEEL (80%AR 20%CO
that the display "V" has lit "u5").
•
Use the knob [2] to set the proper welding source
according to below list:
•
u4 - Powertec 360S.
•
u5 - Powertec 420S.
•
u6 - Powertec 500S.
•
u7 - Powertec 300S.
•
Save the selected value through switch the knob of
the choice wire diameter selection [10] in "1.6
CORE" position – the wire feeder is ready to work.
The display "V" lights the selected source number
(4/5/6/7) for 2 seconds after the supply of the wire feeder
is switched on.

Welding with MIG / MAG method in
Synergic mode (only LF 24 PRO)
To begin welding process with MIG/MAG method in
synergic mode you should:
•
Switch ON the machine which supplies the wire
feeder.
•
Insert the electrode wire into the torch using "Cold
Inch" switch [15].
•
Check gas flow with "Gas Purge" switch [15].
•
Set the knob of the choice wire diameter selection
[10] in the position corresponding to the diameter of
the used wire.
•
Set the knob of the choice welded material and gas
mixture [11] in the position corresponding to the
used material.
If the selected welding process does not have
synergic mode, three horizontal dashes will appear
on the display "A".
•
According to the selected welding mode and
material thickness, set the proper welding voltage
on the welding source.
For synergic
automatically selects the proper wire feeding speed
for each position of the welding source.
automatic speed value can be adjusted in the range
of the ±25% by the WFS Control Knob [2].
•
Obeying the appropriate rules, you can begin to
weld.
Water Cooler Control (only LF 24 PRO)
The LF 24 PRO wire feeder allows the water cooler to
the automatic work with Powertec 360S/420S/500S, i.e.:
•
When a weld is started, the Cooler is automatically
switched on.
•
When the weld is stopped, the Cooler continues to
run for about 5min., after this time, it is automatically
switched off.
•
If the weld is restarted in a time lower than 5min.,
the Cooler continues to run.
The wire feeder has the possibility to switch the
automatic work of the water cooler off and set it in
continuously work. If it is necessary to change the water
cooler kind of work, you should:
•
Switch off the machine which supplies the wire
feeder.
•
Set the knob of the choice wire diameter selection
[10] in "1.0" position. Set the knob of the choice
welded material and gas mixture [11] in "CRNI
(98%AR 2%CO
•
Switch the supply of the wire feeder on.
•
Within 15s switch the knob of the choice wire
diameter selection [10] in "1.2" position and the
knob of the choice welded material and gas mixture
[11] in "STEEL (100%CO
cooler has been switched on and the display "V"
has lit "on".
If it is necessary to return the automatic work of the
water cooler you should do the foregoing actions again
(the display "V" has lit " 5'' ").
