iPAK MPX Cascade

Medium Frequency DC Cascade Inverter Controls

iPAK MPX is an integrated timer/controller/inverter system for MF resistance welding which uses modular architecture to fire multiple MFDC power supplies. 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.
