Welding with MIG / MAG method in
Synergic mode (only WF24S)
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.
WARNING
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.
WARNING
For synergic welding mode the machine automatically
selects the proper wire feeding speed for each position of
the welding source. The automatic speed value can be
adjusted in the range of the 50% by the WFS Control
Knob [2].

Obeying the appropriate rules, you can begin to weld.
Water Cooler Control (only WF24S)
The WF24S wire feeder allows the water cooler to the
automatic work with 355S/425S, 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 )" position.
2

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 )" position – the water cooler has
2
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'' ").
English
The display "V" lights information about work mode of the
water cooler (5"/on) for 2 seconds after the supply of the
wire feeder is switched on.
Changing Driving Rolls
Turn the input power OFF at the welding power source
before installation or changing drive rolls and/or guides.
WF24 and WF24S are equipped with drive roll V1.0/V1.2
for steel wire.
For others wire sizes, is available the proper drive rolls kit
(see "Accessories" chapter) and follow instructions:

Turn the input power OFF.

Release the pressure roll levers [24].

Unscrew the fastening caps [25].

Open the protection cover [26].

Change the drive rolls [17] with the compatible ones
corresponding to the used wire.
Be sure that the gun liner and contact tip are also sized to
match the selected wire size.
For wires with the diameter larger than 1.6mm, the following
parts are to be changed:
● The guide tube of the feeding console [28] and [29].
● The guide tube of the Euro Socket [30].

Replace and tighten the protection cover [26] to the
drive rolls.

Screw fastening caps [25].

Manually feed the wire from the wire reel, the wire
through the guide tubes, over the roller and through
the guide tube of Euro Socket into liner of gun.

Lock the pressure roll levers [24].
