2. Projection height applications which are controlled by spindle stops.
(Spindle rotation must stop at same moment that axial travel stops.)
If a LANCER is used on a torque
application, the power source must have a torque control feature.
Even though the LANCER was originally
designed for use on projection height applications, when properly equipped,
the LANCER has proven itself to be an effective method for
driving studs to a torque requirement.
Unlike the SENTINEL series of stud drivers,
the LANCER does not include a clutch mechanism to control the driving
torque of the studs. Torque control must be achieved by
one of the following methods:
● Controlling the stall torque of the power tool.
● Electronically monitoring and controlling the torque.
● Mechanically interrupting the power source at the desired level. When used on a torque application
care should be taken to insure that all rotational force is eliminated
before
the LANCER is removed from the stud. Failure to do
this could result in damage to the stud or stud driver. This
could also cause the jaws to lock onto the stud thus
preventing easy removal of the LANCER at the end of the drive
cycle.
