Torque Trigger Option
This option specifies a torque level to sense when the
upper and lower parts make contact. Prior to contact,
the motor is spinning the tool in the air using a very low
amount torque. At contact, there is an increase in the
torque required to maintain a constant angular velocity,
at which point the weld is considered to start (i.e. the
weld timer and counter are started). Note that the welder
begins to sense the torque after reaching the TRIGGER
Position. To enable this option, press the
button and then the

torque level at which the weld will start. The
value specifies the amount of time the welder will
(s)
wait between reaching the TRIGGER Position and the
sensing of the torque trigger. If torque trigger does not
occur within this time, the machine will abort the cycle
and display an error. The

For this option to work properly, the torque trigger value
must be set above the torque required to keep the spin
tool running before part contact (i.e. in free air). To set
the torque trigger value correctly, follow these steps:
1. Program all welder settings as desired (refer to
other sections in this manual if needed).
2. Disable the
