Starting A Weld Cycle

All weld cycles must be initiated from the

RUN

screen

after the machine is initialized and with the press at the
top-of-stroke position. If not already on this screen,
press the

RUN

button first (see Figure 5-2). If you had

powered down the welder or pressed the Abort button,
the screen may instruct you to press the

RESET FAULT

button and then reset the machine by activating the

RUN

switches. After the reset process is completed, the

welder is ready to run a cycle, which is indicated by
the smiley face in the upper left corner of the screen.
If a frowning face appears instead, it signifies that
the welder is not ready for one of several reasons (for
example, the part presence sensor is not activated if the
Part Present option is enabled).

To run a cycle, press both

RUN

switches simultaneously.

The press will begin to descend and spin motor will
accelerate. Both servos will reach their programmed
weld speeds by the time the press reaches the trigger
position (defined in

SETUP

>

PRE-TRIGGER

tab >

TRIGGER

Position

). The Trigger Indicator (see Figure

4-1) will turn on when the weld starts, which occurs
at the Trigger position if the Torque Trigger Option
is disabled, or when the trigger torque is sensed if the
Torque Trigger Option is enabled. The weld phase
continues until the selected welding parameter (time,
number of rotations, vertical distance, or energy) has
been reached, at which point the Trigger Indicator turns
off. The spin motor then stops and the welder begins the
hold phase, during which the press moves according to
the settings defined in the

Hold Setup

menu. To complete

the cycle, the press retracts to the top-of-stroke position
and the

RUN

screen is populated with weld process data

results. The base switches must remain actuated until
the start of the hold phase; otherwise, the cycle will be
aborted and no weld data will be displayed.

If a weld cycle completes successfully, the smiley face
appears to indicate that the machine is ready to run
another cycle. If a cycle terminates abnormally, a fault
message will be displayed on the screen describing
the error condition. The fault must be cleared and the
welder reset before another cycle can be initiated.
