Gullcos new microprocessor control not only provides improved speed regulation to Gullcos proven "GP" range of positioners. It also allows the positioner to be expanded into a fully automated welding cell. The control uses a tach feedback system to ensure smooth and accurate rotation of the workpiece and has the ability to activate pneumatic welding gun holder and wire-feed/arc activation signals, based on an operator defined welding cycle. The programmable microprocessor also provides adjustable positioning timing cycles, amount of weld rotation and weld on/off through 360°.
