. Check that the wire runs through the correct groove of
the pulley.
4. Fold down the pressure arms
E2
and return the clamping nuts
E1 to the
vertical position.
5. Adjust the pressure of the clamping nut to ensure smooth movement of the
wire without deforming the wire. Press button
A13
, located in the feed area
of the machine, to start the feed motor. The adjustment screw is located
under the plastic screws
E1
.
6. The coil brake is set by the manufacturer. If necessary, it can be adjusted
with screw
D4
so that when the feed stops, the coil stops in time and the
wire does not become too loose. However, an over-tightened brake puts
unnecessary stress on the feeding mechanism and can cause the wire to
slip in the pulleys.

ADJUSTING THE CLAMPING FORCE OF THE FEED PULLEYS
The amount of clamping force of the feed pulleys is important for the reliable
operation of the feeding mechanism.
The amount of force depends on the type of welding wire, for aluminium or
tubular wire we choose a smaller clamping force.
If the clamping force is insufficient, the pulleys slip and the feed rate becomes
irregular.
If the pressure force is too high, the mechanical wear of the bearings increases,
the pressure mechanism does not fulfil its protective function and in case of
increased resistance of the wire feed (damaged or contaminated bovden, baked
wire in the grommet, etc.), the wire does not slip and there is a risk of the wire
being displaced to the side. In the extreme case, the motor may be completely
blocked and the gearbox will be unduly mechanically stressed, the electric motor
and the power output of the controller will be overloaded and may be damaged.
Clean the pulleys of canned oil before starting.
