EN6001 Constant Current AC Controls

The EN6001 is a versatile Single Phase AC control. Among its many features, 64 Weld programs, that can be executed as single sequences or chained to produce a variety of sequences. Constant Current – using primary or secondary sensor. The EN6001 provides 3 valve outputs can be used for multi-welding, or other functions depending on application requiring outputs before/after the weld. In additional 6 Programmable inputs and 4 Programmable outputs allow selection of assigned functions such as Retract, Parts counter management, Lockout. The EN6001 Includes a USB port for updates or backups. An Optional Ethernet adapter is available for automation using Ethernet IP control, or Modbus TCP/IP or full data exchange and I/O control. ENLINK 6001 Software is available for programming and monitoring via PC.
