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 M8, which is
placed inside of the sleeve frame after unscrewing the
fastening cap of the sleeve.
21. Fastening cap.
22. Adjusting screw M8.
23. Pressing spring.
Turning the screw M8 clockwise increases the spring
tension and you can increase the brake torque.
Turning the screw M8 counterclockwise decreases the
spring tension and you can decrease the brake torque.
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.
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 methods
Welding with MIG / MAG method
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].
According to selected welding mode and material
thickness set the proper welding voltage with knob [3]
and the wire feeding speed with WFS knob [2].
Obeying the appropriate rules, you can begin to weld.
Welding with MMA (SMAW) method
The LF33S wire feeder enable Manual Metal Arc welding
process that uses a consumable electrode coated in flux
by cooperating with CC (constant current) power sources
like DC 400, DC 655 or V350 PRO.
In order to start welding process with MMA method you
should:
Connect the wire feeder to over mentioned CC power
source by the combined cable.
Connect welding torch into output socket [9].
Switch the power source in CC mode.
Set required welding current by adjusting knob [3].
Obeying appropriate rules you can begin to weld.
