Fronius USA LLC expanded the range of functions of its intelligent TPS/i Robotics power source. This system can now be equipped with the stable Cold Metal Transfer (CMT) welding process using a new additional package. The power source consists of interconnected and fully synchronized components. It has a high-performance processor and a high-speed bus, enabling data to be exchanged quickly. Two synchronized wire feeders ensure dynamic and precise wire feeding and, thus, high process stability.
