Adaptive Control for Resistance Welding
The PRC7000 control for resistance welding provides precise adjustment of the welding current to eliminate spatter and rework. Innovative software tools and a modular design enable up to 90 percent faster commissioning. The PRC7000 can store 10,000 welding programs that can be easily selected and built via a drag-and-drop graphical interface to program sophisticated welding sequences that can have 100 or more separate heat blocks. Through user-friendly programming tools, each heat block can be configured to handle specific weld criteria.
The system also features a new, Industry 4.0-ready dual-processor architecture for both process control and communications with higher-level automation systems. This enables high data transfer rates without affecting the process control; combined with an integrated web server, this supports wireless operator control and diagnostics via mobile devices.
Compared to previous systems, the PRC7000 reduces energy consumption by 30 percent in operating mode and up to 80 percent in idle mode. New performance electronics reduce power loss and enable the use of smaller, more compact cooling systems to minimize the system’s footprint.
Advances in hardware and software address key developments in automotive manufacturing, such as an increased use of high-strength steel, aluminum and next-generation materials in vehicle bodies and parts. The controller can adjust the quality of the weld within a millisecond time frame. A force feedback system reads the expansion of aluminum due to heat and can regulate the weld through adaptive control of the weld tip pressure and the current being applied.
