control for motor rotation. A suitable working pressure
when cutting usually lies between 100 and 130 bar, but
varies depending on how many wheel sets are used in
the magazine, how much wire is in use and the
hardness of the material to be cut.
9. When material is cut away the working pressure can
drop, which is shown on the display, and the magazine
must be tensioned. Do this by turning the knob on the
pressure reduction block clockwise.
10.The output tension on the magazine is shown by an
indicator on the machine (shown in the min position).
When the magazine cylinder is fully tensioned, the
machine must be stopped and the wire must be wound
around a new wheel set. Then continue to cut as
above.
CAUTION
Always clean all the equipment at the end of
the working day.
