AUTOMATIC HEIGHT CONTROL

With the CAS-0100 the actual weld current is sensed continuously by means of a current shunt, 50mV full scale. The signal is filtered, amplified and compared to a set point value. Any error is fed to a second order control loop which sends a velocity signal to the height adjustment drive. The control holds the error to zero for a flat piece of work, or for a weld with a uniform rise along its length. The drive for the motor is a four-quadrant servo control which enables smooth accurate height corrections. Therefore, the control can easily follow contours. In addition to BUG-O carriages, the CAS-0100 can be used on fixtures or manipulators to provide constant wire stick-out length. It provides automatic control of welding torch-to-work distance with the following:• Multi-turn potentiometer, for adjusting current set point, which is directly read from a turn-counting dial. • Automatic shut-off of height-adjusting drive when current is off or falls below a pre-set lower limit. • Built-in time delay after arc is struck before drive activation. • Manual up-and-down height adjustment buttons which override automatic controls, and function when drive is either active or inactive. • Speed potentiometer sets adjustment speed in manual mode and also limits top speed in automatic mode. • Self-contained control, independent of the rest of the equipment, such as drives, power sources, wire feeders, etc. NOTE: CAS-0100 requires a 50mV Current Shunt (500 amp min.)
