Adjustments of Brake Torque of Sleeve
To avoid spontaneous unrolling of the welding wire the
sleeve is fitted with a brake.
Adjustment is carried by rotation of its screw M10, which
is placed inside of the sleeve frame after unscrewing the
fastening cap of the sleeve.
Figure 8.
21. Fastening cap.
22. Adjusting screw M10.
23. Pressing spring.
Turning the screw M10 clockwise increases the spring
tension and you can increase the brake torque.
Turning the screw M10 counterclockwise decreases the
spring tension and you can decrease the brake torque.
After finishing of adjustment, you should screw in the
fastening cap again.
Adjusting of Force of Pressure Roll
Force
Pressure force is adjusted by turning the adjustment nut
clockwise to increase force, counterclockwise to decrease
force.
WARNING
If the roll pressure is too low the roll will slide on the wire. If
the roll pressure is set too high the wire may be deformed,
which will cause feeding problems in the welding gun. The
pressure force should be set properly.
pressure force slowly until the wire just begins to slide on
the drive roll and then increase the force slightly by turning
of the adjustment nut by one turn.
Inserting Electrode Wire into Welding
Torch
Connect the proper welding torch to the Euro socket, the
rated parameters of the torch and of the welding source
shall match.
Remove the gas diffuser and contact tip from the welding
torch.
Set the wire feeding speed in the position of about
10m/min by the WFS knob [2].
Switch the Cold Inch / Gas Purge switch [15] in the
position "Cold Inch" and keep in this position until the
electrode wire leaves the contact tip of the welding torch.

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 WF24S) 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 WF24S)
The wire feeder WF24S can work with below power
sources in synergic mode:

355S.

425S.
The feeder is set for co-operation with 425S (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
display "V" has lit "S").

Use the knob [2] to set the proper welding source on
display:
- 355 S
- 425 S

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
(355S/425S) for 2 seconds after the supply of the wire
feeder is switched on.
