Resistance Brazing System

Miyachi Unitek Corporation offers the IPB-5000A inverter power supply to provide metallurgical bonding of tin-plated copper ribbon and buss bar interconnects for PV panel manufacturing. The resistance brazing system, which consists of a power supply, transformer and brazing head, is easily integrated into most PV panel manufacturing operations.
The IPB-5000A offers 5 kHz fast feedback for the best welding control, as well as a full-color LCD to show all parameter traces for easy understanding of the welding process. The system operates in constant current, voltage or power feedback modes and is also capable of welding in combination mode to address even the most challenging application or process conditions. A pre-check function determines resistance prior to the weld, while comparator and envelope functions monitor the weld to ensure quality.
“The IPB-5000A has been successfully integrated into PV manufacturing facilities on a global basis since 2003.  Its eight-year track record has delivered the measured results and process control not achievable with other technologies,” said John DiGiacomo, Miyachi Unitek Regional Sales Manager.
