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 Allen screw M8,
which is placed inside of the sleeve frame after
unscrewing the fastening cap of the sleeve.

2. Adjusting Allen screw M8.
3. Pressing spring.
Turning the Allen screw M8 anticlockwise increases the
spring tension and you can increase the brake torque
Turning the Allen screw M8 clockwise 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
The pressure arm controls the amount of force the drive
rolls exert on the wire.
Pressure force is adjusted by turning the adjustment nut
clockwise to increase force, counterclockwise to
decrease force. Proper adjustment of pressure arm
gives the best welding performance.
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
Turn the welding machine off.
Depending on welding process, connect the proper
gun to the euro socket, the rated parameters of the
gun and of the welding machine should be matched.
Remote the nozzle from the gun and contact tip or
protection cap and contact tip. Next, straighten the
gun out flat.
Turn the welding machine on.
Depress the gun trigger to feed the wire through the
gun liner until the wire comes out of the threaded
end.
When trigger is released spool of wire should not
unwind.
Adjust wire spool brake accordingly.
Turn the welding machine off.
Install a proper contact tip.
Depending on the welding process and the type of
the gun, install the nozzle (MIG process) or
protection cap (FCAW-SS process).
WARNING
Take precaution to keep eyes and hands away from the
end of the gun while the wire is being come out of the
threated end.
Changing Driving Rolls
WARNING
Turn the input power off of the welding power source
before installation or changing drive rolls.
BESTER 210MP
is equipped with drive roll V0.8/V1.0 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 lever [1].
Unscrew the fastening cap [2].
Change the drive roll [3] with the compatible ones
corresponding to the used wire.
WARNING
Be sure that the gun liner and contact tip are also sized
to match the selected wire size.
Screw fastening cap [2].
Manually feed the wire from the wire reel, the wire
through the guide tubes, over the roller and guide
tube of Euro Socket into liner of gun.
Lock the pressure roll lever [1].
