iPAK

Medium Frequency DC Inverter Controls

iPAK is an integrated timer/controller/inverter system for MF resistance welding. The control section is housed in a cassette-type casing, which simply mounts onto the power pack for ease of maintenance. Millisecond precision, constant current and constant power operation, with comprehensive monitoring, assures weld quality.
