SECTION V - OPERATION
5.9 ROTATION CALIBRATION
5. Create or recall from the LIBRARY the appropriate Weld Schedule and
connect the Weld Head to be calibrated. Insure that the system is SAFE to
rotate and that the System Mode is in TEST. Note the starting position of the
Weld Head and Press Sequence Start. At the end of the Sequence the weld
head should have rotated the programmed amount.
6. If it has not rotated or moved the correct distance then adjust the Weld Head
Rotation Cal Potentiometer
7. Repeat 5 and 6 until the head is calibrated.
5.10 WIRE FEED CALIBRATION
NOTE
For proper operation, weld head Wire Feed 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 and the Weld Head
manual. Wire Feed calibration is done by feeding the wire and measuring actual
speed. Before proceeding CHECK THAT THE HEAD IS FREE TO FEED
WIRE 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:
