Torque Mounting Bolts

E-STOP
1. Press .
2. Disconnect and lockout the AC power.
3. Close and lockout the machine air.
4. Ti g h t e n t h e u p p e r t o o l i n g t o t h e s p r i n g
bridge with a torque wrench to 100 ft-lbs.
NOTE
: 100 ft-lbs = 13.83 Kg-m = 136 Nt-m
5. Tighten the lower tooling bolts to the table with a
torque wrench set to 100 ft-lbs.
6. Attach and secure any air lines or sensor wiring to
the tooling.

Final Tooling Prep

1. Turn on the AC power.
2. Apply the compressed air.
3. Clear any E-STOP.
4. Press the E-STOP RESET button.
5. Press the HYDRAULIC PUMP ON push button.
6. Load the program for the currently installed tool-
ing. Refer to Figure 6 -29 and Section 8 - Machine
Operation, Selecting a Setup File
7. Initiate a Machine Reset procedure.
See Figure 7–5.
8. Retract tooling stanchion alignment pins. See Figure
7–11.
9. Remove any protective parts from tooling.
10. Install any mounting bolts that were inaccessible
with the tool closed. Torque them to 100 ft-lbs.

Tune Drive to Tooling

During the Autotune process, the machine seeks the
operating frequency that optimizes the drive to the load
presented by the upper tooling assembly. If an Autotune
is not performed, the drive will be fighting the natural
resonance of the tooling. The results: wasted energy and
possible inferior welding.

CAUTION
Make sure to retract the stan-
chion alignment pins before
proceeding to tune the drive
heads.
Failure to retract the pins may result in dam-
age to the tooling. See Figure 7-11 for a
picture of a stanchion with the alignment
pin retracted.

It is important to perform an
Autotune every time the tool-
ing is changed. Each set of
tooling has its own unique
resonant frequency. Even tooling sets that
are designed to be identical will have a
slightly different tuning load due to machin-
ing and bolt torquing stresses.
