Entron Controls for Resistance Welding EN2000

Dual Schedule/Dual Sequence S2H Controls

The EN2000 Series Control is ideal for programming schedules for most welding applications for ferrous and some non-ferrous metals, multiple thickness of materials and special part configurations.

  • Store Two Schedules
  • Every parameter of each schedule individually accessible
    Each schedule can store 5 distinct and totally different parameters
    All schedules retained in memory with power off

  • Single contactor circuit
  • Single valve circuit
    Contactor failed detection

  • Control can be INTERFACED with external Programmable Logic Control (PLC)


  • Simple to Program
  • Direct Reading Digital Data Display
