These welding positioners are positive drive rotary turn tables complete with mounting flange, drive and tilt mechanisms which incorporate a microprocessor-based pulse width modulation motor control. A low-voltage permanent magnet motor and gear head power unit assembly drives the welding positioners. The microprocessor motor control enables the operator interface of start, stop, clockwise rotation and infinitely variable control of the speed, within the range of the model.
Rotation speed is electronically controlled using an optical tachometer on the gear motor's back. Speeds within the range of the model are infinitely variable in both clockwise and counter-clockwise directions through a rotary speed adjustment potentiometer located on the remote control. Table tilt is manually set at any desired angle, from 0° through 90°, quickly and easily. Safety is greatly enhanced with Gullco's low-voltage (24 V) control and power supply system.
