TOP OF STROKE Position
This button is used to set the vertical position to which
the welder head returns after completing a weld cycle,
as shown in Figure 5-7. A position of 0 corresponds to
the highest position (which is also the machine “home”
position). A non-zero setting indicates that the Top of
Stroke (TOS) position is lower than the home position
by the programmed amount. The TOS position can be
entered directly by pressing the
Position (mm ) field.
Alternatively, the TOS position can be “taught” by first
pressing the
DOWN button and selecting the VERT . Jog
Speed (Low, Medium, or High) , then activating the RUN
switches to jog the head to the desired position, and
finally pressing the
Transfer button to assign the current
jog position (displayed in the Jog Pos . (mm) field) as the
TOS Position.
The Move To button is used to move the head to the value
displayed in the Position (mm) field. After pressing this
button, activate both RUN switches and wait for the
value in the Jog Pos . (mm) field to match the Position
(mm) value.
TRIGGER Position
This button is used to set the vertical position at which the
spin tool and machine head reach the programmed weld
speeds, as shown in Figure 5-8. If Torque Triggering is
disabled (see below), the weld starts at the
TRIGGER
Position. This position should be set slightly higher than
the position at which the parts to be welded start to come
in contact. Above this position, the spin motor is being
accelerated from rest to the weld RPM and the head
is moving rapidly down. After reaching this position,
the spin RPM and vertical speeds are maintained at the
programmed values. The
TRIGGER Position can be
entered directly into the Position (mm) field or taught
by jogging the head as described in setting the
TOP OF
STROKE Position.
