SECTION V - OPERATION
5.9 ROTATION CALIBRATION
NOTE
For proper operation, Weld Head rotation speed must be calibrated for the power
supply it is connected to. If weld heads are switched they must be re-calibrated on
that system before welding commences .
1. Insure that the weld head is connected per section III. Rotation calibration is
done by moving the torch and measuring actual speed. Before proceeding
CHECK THAT THE WELD IS FREE TO ROTATE SAFELY.
2. To manually calibrate the user will need to have a Weld Schedule in the Library
programmed in accordance to the Calibration Procedure contained in the
operation manual for the particular Weld Head being used.
3. A MANUAL calibration schedule will always be run in TEST Mode and usually
contains the following:
PRE-PURGE-POST UP-SLOPE-DOWN ROT-DLY
000 000 00.0 00.0 CCW 00.0

4. LEVEL 1 TIME needs to be set for the time it will take to rotate ONE
REVOLUTION at the selected LEVEL 1 PRI--RPM rate. The RPM rate is
usually set at a rate that the head is most frequently used at
LEVEL 2 is added with ROTATION turned OFF. This is to allow the operator
time to see if 1 revolution was completed before the “Return to Home”
functions engages at the end of the Sequence. LEVEL 2 CAN BE OMITTED
FOR WELD HEADS THAT DO NOT HAVE A RETURN HOME
