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.
Decrease the 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.
WARNING
Take precaution to keep eyes and hands away from the
end of the torch while feeding wire.
WARNING
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 24M 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 24M
PRO)
The wire feeder LF 24M PRO can work with below
power sources in synergic mode:
•
Powertec 305S.
•
Powertec 365S.
•
Powertec 425S.
•
Powertec 505S.
The feeder is set for co-operation with Powertec 425S
(factory default).
If it is necessary to change the power source, you
should:
English
•
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 "S").
•
Use the knob [2] to set the proper welding source on
display:
• 305 S
• 365 S
• 425 S
• 505 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
(305S/365S/425S/505S) for 2 seconds after the supply
of the wire feeder is switched on.
Welding with MIG / MAG method in
Synergic mode (only LF 24M 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 ±50% by the WFS Control Knob [2].
•
Obeying the appropriate rules, you can begin to
weld.
Water Cooler Control (only LF 24M
PRO)
The LF 24M PRO wire feeder allows the water cooler to
the automatic work with Powertec 365S/425S/505S, i.e.:
