Loading the Wire Spool
Maximum 5kg spools. Accepts plastic, steel and fiber
spools onto 51mm spindle. It is possible to use other
spools after using the appropriate adapter, which can be
purchased separately (see "Accessories" chapter).
Loading the Electrode Wire
Turn the input power OFF.
Open the spool wire case.
Unscrew the locking nut of the sleeve [13].
Load the spool wire on the sleeve so that the spool
turns clockwise when the wire is feed into the wire
feeder.
Make sure that the spindle brake pin goes into the
fitting hole on the spool.
Screw in the locking nut of the sleeve.
Open the wire drive door.
Put on the wire roll with the correct groove
corresponding to the wire diameter.
Free the end of the wire and cut off the bent end
making sure it has no burr.
WARNING
Sharp end of the wire can hurt.
Rotate the wire spool clockwise and thread the end
of the wire into the wire feeder as far as the Euro
Socket.
Adjust force of pressure roll of the wire feeder
properly.
Adjustments of Brake Torque of Sleeve

19. Adjusting Screw M10.
20. Pressing Spring.
Turning the M10 screw clockwise increases the spring
tension and increase the brake torque
Turning the M10 screw anticlockwise decreases the
spring tension and decrease the brake torque.
After finishing of adjustment, you should screw brake
locking nut again.
Adjusting 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 weak, the roll will slide on the
wire. If the roll pressure is set too heavy the wire may be
deformed, which cause feeding problems in the welding.
The pressure force should be set properly. For this
purpose 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.
