Section B Operation
Weldhead Calibration
The software program in the orbital welding power-supply provides for
weldhead rotor speed and motor controller calibration. This calibration
program consists of driving the rotor at two predetermined speeds:
1.0 and
0.5 RPM. The start and end of each rotation are detected by the passage of
the reed switch or “home” sensor in the weldhead. The rotation is clocked by
the computer and, by process of adjusting and recalculating, provides very
accurate and consistent speeds.
NOTE: IT IS MANDATORY THAT THE WELDHEAD BE
CALIBRATED EACH TIME THE SYSTEM IS TURNED ‘ON’.
FAILURE TO CALIBRATE THE WELDHEAD MAY RESULT IN THE
WELDHEAD OPERATING AT A “ROUGH” ADJUSTMENT THAT
MAY NOT PROVIDE CORRECT ROTOR SPEED AGAINST THE
CONTROLLERS’ DEMAND SPEED.

The report generated by this unit is not as elaborate as the report from the
ACL, however; it does show some very important information. It shows both
the MOTOR and TACH gain values. The calibration and adjustment is still
the same. The Zero Offset for both the MOTOR and TACH is also shown:
MOTOR Calibration report
MOTOR gain: -4.6% Zero offset: 0.30 RPM
TACH gain: 1.9% Zero offset: 0.02 RPM
Should these MOTOR & TACH gain values return with number of 0.00% and
0.00 RPM, the calibration was invalid and should be re-run.
Results containing all zeros are an indication that the weldhead is in need of
service:
MOTOR Calibration report
MOTOR gain: 0.0% Zero offset: 0.00 RPM
TACH gain: 0.0% Zero offset: 0.00 RPM
NOTE: If all values for MOTOR or WELDER calibration are zeros, it means
that weldhead calibration did not complete successfully and is not valid.
A recalibration is highly reccomended at this time.
Section C Accessories
Table Edge Benchmount
The DiamondBack™ weldhead can be used while held in the operator’s
hand. However, due the weight and size of the weldhead, at times it
may be necessary for the operator to use both hands to manipulate parts
within the weldhead and which requires the use of a Table Edge Weldhead
Benchmount. This Table Edge Benchmount, P/N 005-0680, can be affixed
to any table or counter edge and can hold the DiamondBack™ Model 5006
orbital weldhead.
Extension Cable
When longer weldhead cables are needed, a weldhead extension cable is
also available in a 25’ length. The extension cable (P/N 005-0635) has all
the connections needed to connect the DiamondBack™ to the CobraTig
®

welding leads, gas, and control interface.
