iPAK2

Medium Frequency DC Inverter Controls

iPAK2 is the next generation of our integrated timer/controller/inverter system for MF resistance welding. Like the original iPAK, the iPAK2 control section is housed in a cassette-type casing, which simply mounts onto the power pack for ease of maintenance and continues to deliver millisecond precision, constant current and constant power operation, comprehensive monitoring, along with new features to assure your weld quality. Please refer to the iPAK2 CPU Bulletin below.
